Typical applications of the various stainless steel types
| TypesTypical | Applications |
| 420 (martensitic) | Cooks and professional knives, spatulas etc |
| 430 (ferritic) | Table surfaces, equipment cladding, panel (ie components requiring little formability or weldability). Used for moderately corrosive environments (e.g. vegetables, fruits, drinks, dry foods, etc). |
| 304 (austenitic) | Vats, bowls, pipework, machinery parts (i.e. components requiring some formability or weldability). Corrosion resistance superior to 430. |
| 316 (austenitic) | Components used with more corrosive foods (e.g. meat/blood, foods with moderate salt contents), which are frequently cleaned, with no stationary solids and not under excessive stress. |
| 1.4539 (austenitic) | Used with corrosive foods (e.g. hot brine with solids that act as crevice forms, stagnant and slow moving salty foods). |
| 1.4462 (duplex) | Used with corrosive foods (e.g. hot brine with solids, stagnant and slow moving salty foods). Higher strength than austenitics. Good resistance to stress corrosion cracking in salt solutions at elevated temperatures. |
| 6%Mo. types (austenitic) | Used with corrosive foods (e.g. hot brine with solids, which act as crevice formers, stagnant and slow moving salty foods). Good resistance to stress corrosion cracking in salt solutions at elevated temperatures. Used in steam heating and hot work circuits, hot water boilers, etc |
