3CR12 vs Mild Steel -What’s the Difference

3CR12 vs Mild Steel

If you’re in the market for a steel product, chances are you’ve come across two popular options: 3cr12 and mild steel. But which one is right for your project? In this blog post, we’ll break down the pros and cons of both materials so that you can make an informed decision about which is best for your needs.

3CR12 Steel

3CR12 is an alloy steel made from a combination of chromium, nickel and 12 per cent iron. The presence of these metals gives 3cr12 some unique features that help it stand out from other steels on the market. For starters, 3CR12 is corrosion resistant due to its high chromium content, making it ideal for wet and humid environments where other metals may not hold up as well. Additionally, it has a higher tensile strength than mild steel, meaning it can withstand more strain before breaking or bending. Finally, 3cr12 is cheaper than most other types of stainless steel, making it a cost-effective option for projects requiring high-quality alloys.

Mild Steel

Mild steel is a type of low-carbon steel that contains 0.25 per cent carbon or less. It has several advantages over other types of steel, including lower cost, greater malleability and weldability. Mild steel also has relatively good formability when compared to other steels – meaning that it can be easily reshaped without sacrificing its strength or durability – making it great for home improvement projects like metalworking or welding furniture frames together. However, unlike 3CR12, mild steel does not offer any corrosion resistance, so it should not be used in wetter environments unless treated with protective coatings like paint or varnish first.

Difference Between 3CR12 and Mild Steel

Chemical Composition

3CR12 stainless steel has a chemical composition of chromium, carbon and iron. Mild steel has a similar composition to carbon and iron but with lower chromium content. As a result, 3CR12 stainless steel is more resistant to corrosion than mild steel.

Tensile Strength

3CR12 stainless steel also has a higher tensile strength than mild steel. The tensile strength is the maximum amount of force that can be applied to a material before it breaks. As a result, 3CR12 stainless steel is more durable and can withstand more force without breaking.

Yield Strength

3CR12 stainless steel also has a higher yield strength than mild steel. The yield strength is the point at which a material starts to deform permanently under load. As a result, 3CR12 stainless steel can better withstand heavy loads without deforming.


3CR12 stainless steel is also more ductile than mild steel. Ductility is the ability of a material to deform under load without breaking. As a result, 3CR12 stainless steel can be formed into complex shapes that would otherwise be impossible with mild steel.


One downside of 3CR12 stainless steel is that it is more expensive than mild steel. However, the increased cost is offset by the improved durability and performance of 3CR12 stainless steel.


When deciding between 3CR12 vs mild steel for your next project, keep in mind their respective strengths and weaknesses. Both metals have their own unique properties, which make them suitable for different applications – 3CR12 offers superior corrosion resistance, while mild steel offers greater malleability at a lower price point, so consider what your primary needs are before choosing one over the other!
