Common types and characteristics of stainless steel


Common types of stainless steel include: austenitic stainless steel including 304, 316, 321, etc.; ferritic stainless steel including 430, 409, 439, etc.; martensitic stainless steel including 17-4PH, etc.

Features of stainless steel:

1. Corrosion resistance: Stainless steel has good corrosion resistance and can work stably for a long time in harsh environments such as atmosphere, water, acid and alkali.

2. Good mechanical properties: Stainless steel has high strength and hardness, good plasticity and ductility, and is easy to process and form.

3. Excellent thermal performance: Stainless steel has good thermal stability and heat resistance at high temperatures, and is not easy to deform and melt.
