Grades of Steel: The Building Blocks of a Sustainable Future

As one of the most versatile and widely used materials in modern society, steel comes in various forms and grades. These grades are classified based on their composition, properties, and intended use, making them essential building blocks for many industries. For recycling purposes, it’s important to note that not all steels are created equal. Some grades are easier to recycle than others, while some require specialized processes that can be costly and energy-intensive. Therefore, understanding the different grades of steel is crucial in maximizing the efficiency of the recycling process.

Basic Carbon Steels

Basic carbon steels make up a significant portion of the world’s steel production. They consist mainly of iron and carbon, with small amounts of other elements such as manganese, phosphorus, and sulfur. These steels are relatively easy to recycle, using traditional methods such as electric arc furnaces. Due to their high recyclability and versatility in applications, they play a crucial role in the circular economy.

Alloy Steels

As the name suggests, alloy steels are made by adding various alloying elements to basic carbon steels. These elements alter the properties of the steel, making it stronger, more resistant to corrosion, or heat-resistant. While they offer improved performance in applications, their complex composition makes them trickier to recycle. Specialized processes are required to extract these alloying elements, which can be energy-intensive and costly.

Stainless Steels

Stainless steels are a type of alloy steel that contains at least 10.5% chromium, making them highly resistant to corrosion. They also contain varying amounts of nickel, manganese, and other elements to enhance their properties. Due to their high resistance to corrosion and heat, they are widely used in industries such as construction, transportation, and food processing. However, the recycling process for stainless steel is more complex and energy-intensive compared to basic carbon steels.

Steel Manufacturing: A Resource-Intensive Process

The production of steel involves high temperatures, large amounts of energy, and a variety of raw materials. The traditional method for manufacturing steel is through the blast furnace process, which uses iron ore, coal, and limestone as the main inputs. This process releases carbon dioxide and other greenhouse gases, making it a significant contributor to climate change.

However, with the advancements in technology and growing concerns for the environment, there has been a shift towards greener methods of steel production. Electric arc furnaces powered by renewable energy sources such as solar or wind are becoming more prevalent. These furnaces can recycle scrap steel and reduce the need for raw materials and energy.

Environmental Benefits of Recycling Scrap Steel

The benefits of steel recycling go beyond reducing the demand for raw materials and minimizing greenhouse gas emissions. It also saves water, reduces air pollution, and conserves energy. The World Steel Association reports that recycling just 1 ton of scrap steel can save 1.5 tons of iron ore, 0.5 tons of coal, and 0.3 tons of water. Additionally, recycling steel can save up to 75% of the energy required to produce it from raw materials.

Moreover, scrap steel recycling also helps in waste management by diverting scrap metal from landfills, reducing their environmental impact. It also creates job opportunities in the recycling industry and promotes a circular economy where resources are reused instead of discarded.

The Future of the Steel Recycling Industry

The demand for steel is expected to continue rising as economies grow and infrastructure development continues. Therefore, the need for sustainable practices in steel manufacturing and recycling will only become more crucial. With advancements in technology and a growing awareness of environmental issues, we can expect to see even more efficient and greener methods of steel production and recycling.

As we strive towards a sustainable future, steel recycling stands as a shining example of how industry and the environment can work together for the greater good.  So, let’s continue to pivot towards green manufacturing, one recycled steel at a time.

Soft Steel Versus Hard Steel

Different types of steel are produced according to the properties required for their application. The strength of steel can be increased by adding alloys such as manganese, chromium, vanadium, and molybdenum. Steel with a low carbon content is known as soft steel, while higher-carbon steels are referred to as hard steels. The hardness of a steel is usually increased by heat treatment, which involves heating the steel to a high temperature and then cooling it rapidly. This process increases the steel’s strength and hardness, but it can also make the steel more brittle.

Most Prominent Grades of Steel

There are many different grades and types of steel, each with its own properties and applications. The most common steels are low-carbon steel, high-carbon steel, tool steel, alloy steel, spring steel and stainless steel.

Low-carbon steels are the most widely used type of steel. They have a carbon content of less than 0.25% and are very ductile. They are used for making auto parts, machine parts, pipes, railway tracks etc.

High-carbon steels have a carbon content of 0.55-1.0%. They are very strong and hard, but also brittle. They are used for making knives, cutting tools, springs etc.

Tool steels are high-carbon steels that contain one or more alloying elements (manganese, chromium, vanadium, or tungsten) in addition to carbon. They are very hard and tough, and are used for making cutting tools, drill bits etc.

Alloy steels are steels that contain one or more alloying elements (manganese, silicon, nickel, titanium etc.) in addition to carbon. They have different properties from carbon steels, and are used for making auto parts, machine parts, pipes etc.

Spring steels are low-carbon or medium-carbon steels that are used for making springs. They have a high carbon content (0.5-1.0%) and are very strong and tough.

Stainless steels are alloys of iron, chromium, and sometimes other elements (nickel, molybdenum, titanium etc.), that resist corrosion and oxidation. The chromium content of stainless steel ranges from 10% to 30%. Stainless steels are used for making kitchen utensils, surgical instruments, food processing equipment etc.

Corrosion Resistant Alloys (CRA’s)

Corrosion resistant alloys are a type of metal that is specially designed and manufactured to resist deterioration, discoloration, degeneration, and other kinds of corrosion. There are many kinds of CRA’s to choose from, all of which ranging in level of resistance. Elements and condition like temperature, CO2, Sulphur, environmental pH, and chloride ion concentration all affect resistance capabilities. These factors in turn affect the passive film’s stability (commencement of overall corrosion or pitting), re-passivation ease of initiated pits, dissolution rates or metal from pits, and the stress corrosion cracking (SCC) risk.

Common CRA’s on the Market:

There are various kinds of Corrosion resistant alloys available on the market today, however, there are 3 in particular that seem to take the lead on current trend. These include 316L (austenitic stainless steel), alloy 22, and Zeron® 100.

316L (Austenitic Stainless Steel) – The most common applications for 316L CRA include clad line pipe building, surface piping, and vessel cladding. One downfall is that it will pit of exposed to oxygen.

Alloy 22 – Alloy 22 is a CRA that is used for conditions that require resistance to oxidizing acid chlorides, wet chlorine, mixtures containing nitric acid or oxidizing acids with chlorine ions, formic and acetic acids, ferric and cupric chlorides, brine, salt water, and even reducing acids like sulfuric acid and hydrochloric acid.

ZERON® 100 – ZERON® 100 is highly resistant to both pitting and corrosion in the presence of salt water, stress corrosion cracking, and similar elemental conditions.

There are several styles, grades, and sizes of steel to choose from. In fact, one of the most common questions among steel consumers involves the different types of steel. In order to know which steel best suits your metalwork project, you must first understand their differences. If you were to ask the American Iron and Steel Institute (AISI), they would tell you that steel can be categorized into four basic groups according to their individual chemical compositions.

These four groups include carbon steel, alloy steel, stainless steel, and tool steel. All steel is composed of both iron and carbon, but vary in type depending on certain physical, chemical, and environmental properties; all of which are determined by the amount of carbon and any additional alloys. Below are the descriptions of the four categories of steel, and facts about each.

Carbon Steel

Carbon steel can be further categorized into three groups: 1) Low carbon, 2) Medium carbon, and 3) High carbon. Low carbon, also called mild steel, is one of the largest categories of carbon steel, and generally contains anywhere from 0.04% to 0.30% carbon content. Depending on its intended use, other additives and alloys can be added to create desired properties. Medium carbon generally contains anywhere from 0.31% to 0.60% carbon content, as well as, a range of 0.60% to 1.65% of manganese content. High carbon steel is informally known as “carbon tool steel” and contains 0.61% to 1.50% carbon content. It is difficult to manipulate, and becomes very brittle when heat-treated.

Alloy Steel

Alloy steel also contains carbon, since all steel contains both carbon and iron. But alloy steel also contains a marginal amount of additional elements, such as Nickle (Ni), Chromium (Cr), and Manganese (Mn). This type of steel is popular and commonly used due to their wide availability, economical costs, ease of processing, and quality mechanical properties. In comparison to carbon steel, alloy steel is more responsive to mechanical and heat treatments. Heated alloy steel comes in wither annealed or normalized.

Stainless Steel

Stainless steel contains added alloys that make is extremely resistant to corrosion in comparison to carbon and alloy steel. This is why it is commonly used in the medical/surgical industries, appliance industry, hardware manufacturing industry, food processing/handling industry, architectural industry, and more. It contains both carbon and iron, as mentioned before, but stainless steel generally contains other alloys as well, such as Chromium (Cr), Molybdenum (Mo), or Nickel (Ni).

Tool Steel

Tool steel is a general term to describe a variety of steels that retain high-hardness and abrasion-resistance properties. Specific applications for tool steel include stamping, extrusion, dies, cutting, mold-making, or impact applications (i.e. hammers).
