What are the differences between 304 stainless steel and 410 stainless steel


304 stainless steel and 410 stainless steel have significant differences in terms of chemical composition, mechanical properties, corrosion resistance, and application fields. The following are the specific differences between the two types of stainless steel: 

Chemical composition:

- 304 stainless steel belongs to austenitic stainless steel, containing a relatively high amount of chromium (about 18%-20%) and nickel (about 8%-10.5%), as well as less carbon (up to 0.08%) and manganese (up to 2%).

- 410 stainless steel belongs to martensitic stainless steel, containing a relatively high amount of chromium (about 11.5%-13.5%), carbon (up to 0.08%), and a small amount of nickel and molybdenum (nickel up to 0.6%, molybdenum up to 0.75%). 

2. Mechanical Properties:

- 304 stainless steel has good elongation and plasticity, making it suitable for processing into shapes or bending.

- 410 stainless steel has a high tensile strength and hardness, but its elongation is low, indicating poor toughness. 

3. Corrosion Resistance:

- 304 stainless steel, due to its high content of nickel and molybdenum, has excellent corrosion resistance, especially stronger resistance to corrosive media.

- 410 stainless steel has relatively poorer corrosion resistance because it has a lower content of nickel and molybdenum. 

4. Application fields:

- 304 stainless steel, due to its corrosion resistance and malleability, is suitable for manufacturing pressure vessels, medical devices, food processing equipment, and chemical equipment, etc.

- 410 stainless steel, because of its high strength and hardness, is suitable for making items that require high wear resistance and strength, such as knives, bearings, valves, etc. For occasions with higher corrosion resistance requirements, 410 stainless steel is not the best choice.
