Summary

- Contains a minimum of 16% chromium and 6% nickel
- Most widely used stainless steels in the world

- Amount of chromium ranges between 10.5% to 18%
- Low nickel content (up to 1%) makes it especially cost effective
- Lower thermal expansion coefficient and higher thermal conductivity than austenitic stainless steel

- Chromium content ranges between 10.5% and 18%, with 0.15% carbon and 0.1% manganese
- Carbon content enables tempering and hardening

- High chromium and low nickel content
- Combines the best of the austenitic and ferritic families
- Annealed structure is 50% austenitic and 50% ferritic
- Low nickel content means low cost

- Contains 17% chromium and 4% nickel
- Strength can be developed by adding titanium, aluminium and other alloys

Characteristics

- Excellent corrosion resistance
- Excellent performance at both high and low temperatures
- Non magnetic when annealed
- Superb hygienic qualities with outstanding cleanability

- Good corrosion resistance
- Magnetic
- Resists stress corrosion cracking

- Corrosion resistance in mild environments
- Magnetic
- Inability to be cold formed

- Excellent pitting-and-crevices corrosion resistance
- High resistance to stress corrosion cracking
- High yield strength
- Poor formability and machinability
- Magnetic

- Good to excellent corrosion resistance
- Can develop high strength with simple heat treatments
- Welding can reduce corrosion resistance by over-aging and sensitisation
- Magnetic

Use

Stainless Steel Grade Chart

Below includes the composition of stainless-steel grades.

A word about standards: The American Iron and Steel Institute (AISI) and the Society of Automotive Engineers (SAE) each devised steel specifications for years, which were often interchangeable. Due to the similarities, they were combined into one, overlapping AISI/SAE system. The AISI designation is no longer officially used, but the name is still used informally. EN are the standard for European stainless-steel grades, though AISI/SAE is extremely popular.
