What Is The Difference Between 304 Stainless Steel And 410 Stainless Steel?

What is the difference between 304 stainless steel and 410 stainless steel?

304 stainless steel and 410 stainless steel are relatively common stainless steel materials, because these two materials are used more, so many friends want to figure out what is the difference between these two stainless steel materials, here from its chemical composition, mechanical properties, corrosion resistance and application fields of these four aspects to talk about it in detail.

Chemical composition

304 stainless steel is austenitic stainless steel, which has good corrosion resistance and plasticity, mainly composed of chromium (Cr) 18%-20%, nickel (Ni) 8%-10.5% and a small amount of carbon (C), manganese (Mn), carbon up to 0.08%, manganese up to 2%.

410 stainless steel is martensitic stainless steel, hardness and strength is relatively high, corrosion resistance is relatively poor, mainly composed of chromium (Cr) 11.5%-13.5%, carbon (C) 0.08%-0.15% and a small amount of nickel (Ni), molybdenum (Mo), nickel up to 0.6%, molybdenum up to 0.75%.
Mechanical property

When it comes to the composition, it has also been said that the elongation and plasticity of 304 stainless steel is relatively high, which is more suitable for processing molding or bending; The tensile strength and hardness of 410 stainless steel are high, but the elongation is low, that is to say, its toughness is relatively poor.
Corrosion resistance

The content of nickel and molybdenum in 304 stainless steel is higher, so the corrosion resistance is higher, especially the resistance to corrosive media is higher; The content of nickel and molybdenum in 410 stainless steel is low, so the corrosion resistance is not as good as other stainless steels.
Field of application

Combining its chemical composition, mechanical properties and corrosion resistance, you can know the application fields of 304 stainless steel and 410 stainless steel.

304 stainless steel with good corrosion resistance and plasticity, suitable for pressure vessels, medical equipment, food processing equipment, chemical equipment and other fields; 410 stainless steel with high strength and hardness is suitable for areas requiring wear resistance and strength, such as tools, bearings, valves and other fields, and 410 stainless steel is not suitable for occasions requiring high corrosion resistance.
