What are the mechanical properties of S30400 stainless steel?

- Yield strength σ0.2: ≥205MPa
- Tensile strength σb: ≥520MPa
- Elongation δ5 (%): ≥40%
- Hardness: ≤187HB; ≤90HRB; ≤200HV

What are the heat treatment properties of S30400 stainless steel?

S30400 can be solution treated in the temperature range of 800-900℃ and then rapidly cooled to increase the hardness of the material. However, it is easy to produce thermal cracks after cold processing, so the temperature and process must be carefully controlled during processing.

What are the corrosion resistance properties of S30400 stainless steel:

S30400 has good corrosion resistance and can maintain good performance under normal atmospheric conditions, water vapor and water quality conditions. However, it cannot work in a medium containing chloride ions and is prone to stress corrosion cracking.

Scope of use of S30400 stainless steel:

S30400 is suitable for food processing, chemical equipment, pressure vessels, pipelines and furniture, and is widely used in places requiring corrosion resistance.

S30400 stainless steel application cases

1. Food equipment industry: S30400 is often used in food processing equipment, pharmaceutical equipment and other fields because it will not cause pollution to food and has good corrosion resistance.
2. Chemical equipment industry: S30400 is suitable for manufacturing chemical equipment, containers, pipelines, etc., and has good corrosion resistance in media such as sulfuric acid and nitric acid.
3. Furniture manufacturing industry: S30400's bright appearance and good corrosion resistance make it a commonly used material in the furniture manufacturing industry.
