What Are the Types of Stainless Steel Materials?

Stainless steel is the abbreviation for stainless and acid-resistant steel. What are the classifications of stainless steel materials? Here is an introduction to help everyone understand better.

Stainless steel material classifications are as follows:

1. Chemical Composition Classification:

  - Chromium series stainless steel (e.g., ferritic series, martensitic series)

  - Chromium-nickel series stainless steel (e.g., austenitic series, duplex series, precipitation hardening series)

2. Metallographic Structure Classification:

  - Austenitic stainless steel

  - Ferritic stainless steel

  - Martensitic stainless steel

  - Duplex stainless steel

  - Precipitation hardening stainless steel

3. Corrosion Resistance Type Classification:

  - Stress corrosion-resistant stainless steel

  - Pitting corrosion-resistant stainless steel

  - Intergranular corrosion-resistant stainless steel

4. Functionality Classification:

  - Free-cutting stainless steel

  - Non-magnetic stainless steel

  - Low-temperature stainless steel

  - High-strength stainless steel
