The Difference Between Stainless Steel and Mild Steel

Over the years of publishing blogs, we have covered the differences between a lot of metals. From ferrous and non-ferrous metal, to hot-rolled and cold-rolled steel, expanded metal and perforated metal, and a few more here and there. But today, we will cover a very basic level of metal acumen: the difference between stainless steel and mild steel.

Continue reading learn how these two types of steel compare to one another, as well as, how you can make some fast cash by recycling your steel scrap.

Steel Matters Because it is Useful and Reusable

Since steel is one of the most widely used metals in the world, it makes sense to learn all the facts surrounding its properties and applications. This is especially true for those who are confused on the different grades and sub-categories available. For instance, many consumers often wonder if there is a significant difference between mild steel and stainless steel. Continue reading to learn the various attributes and qualities of both of these metals.

Stainless Steel Properties

Stainless steel, also known as inox steel or just inox, is an alloy that has a minimum of 10.5% chromium content and a maximum of 1.2% carbon content. Some of the most admired qualities of stainless steel is its resistance to staining, corrosion, and oxidation (rust). For this reason, it is often used in kitchens and food processing plants, as well as industries like medical, electrical, petrochemical, manufacturing, automotive, and more.

Stainless steel comes in many grades and finishes, all of which offer their own unique appeal or performance. Compared to carbon steel, stainless steel has a much higher chromium content, so when exposed to conditions that would otherwise make it rust or corrode, it instead forms a passive coating of chromium oxide that prevents further deterioration. Not only does it not corrode and does not require a protective coating, it is also easy to clean and sterilize.

Properties of Mild Steel

Mild steel is also known as carbon steel, and as mentioned, has a much less chromium content than stainless grades. In fact, The American Iron and Steel Institute officially delineates carbon steel as having no more than 2% carbon, and no other appreciable alloying element. Regardless of its low chromium content, mild steel makes up the majority of the steel production industry around the world because it has such a wide scope of applications.

Mild steel is strong, firm, and ferromagnetic, which means it also contains iron. Because of these properties, mild steel is widely used in manufacturing motors and electrical appliances. On the other hand, carbon steel is less resistant to corrosion, which means it requires a protective treatment of galvanizing or coatings if its application places it in a corrosive environment.

A Comparison of the Two Steel Metals

When it comes to the primary differences between stainless steel and mild steel, it all comes down to strength, ductility, hardness, aesthetics, and cost. Stainless steel contains additional alloying elements, including chromium, nickel, and molybdenum, all of which enhances the mechanical and chemical properties and makes it resistant to corrosion. Mild steel is less brittle, but can be strengthened more by adding carbon.

Common Categories of Corrosion Resistant Alloys

Corrosion resistant alloys are also referred to as “CRA’s”, and they are a popular material in the world of welding and construction due to their high resistance to, you guess it, corrosion. There are various beneficial properties of corrosion resistant alloys, all of which have their own unique applications and functions in various industries all across the nation.

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.
