Martensitic stainless steel Family
Martensitic stainless steels are iron-chromium alloys that contain from 10% to 18% chromium

and can be hardened by heat treatment to high strength levels.
Type JIS SUS410, SUS420J1, SUS420J2, SUS440A, SUS440B, SUS440C stainless steels

are the basic stainless alloys in this group. 
Adding more carbon to the basic martensitic alloy increases hardness.
But, as carbon is increased, chromium content is also increased to as high as 18% to maintain

no less than 10% free chromium for corrosion resistance.
Martensitic varieties find major applications in products that must resist atmospheric oxidation,
mildly corrosive chemicals, and wet or dry corrosion environments found in steam and gas turbine parts,
bearings, and cutlery. The martensitic types are magnetic in all conditions.
 
Martensitic stainless Summary:

• Hardenable by heat treatment
• Magnetic
• High strength
• Moderate resistance to corrosion
