These stainless steels are iron, chromium and carbon alloys,

with typical compositions of C 0.10~1.0% and 13% chromium.

The stainless steel that characterises this group is AISI 420, UNS S42000

Martensitic stainless steels suffer structural changes at high temperatures;

therefore, they usually undergo hardening and tempering heat treatments.

After these treatments, these materials obtain high mechanical properties and sufficient corrosion resistance.

Their most typical application is blade.

Martensitic steel - AISI 420 is essentially a chrome-based alloy which contains minor quantities of other metals.
Martensitic steel is particularly suitable for applications requiring high mechanic and abrasion resistance,
along with a moderate corrosion resistance.
