|Classification||Main ingredient||Metallographic structure
|Cr-based stainless steel||13%Cr (SUS410-based)||Martensite (body-centered cubic structure)||Strongly magnetic||All sorts of industries|
|14%Cr (SUS430-based)||Ferrite (body-centered cubic structure)||Strongly magnetic|
|Cr-Ni-based stainless steel||25%Cr (SUS329-based)||Austenite/ferrite||Magnetic|
|18%Cr-8%Ni (SUS304-based)||Austenite (face-centered cubic structure)||Non-magnetic|
- Others: Austenite/ferrite-based (SUS329-based): High resistance to chlorine.
Precipitation hardened (SUS630-based): High strength.
- Note: Even if stainless steel is non-magnetic, only the superficial layer is magnetized when subjected to strong cold working.
