Martensitic stainless steels typically contain 12 to 17% chromium and nickel in a range of 0 to 5%.
The low nickel content ( compared to austenitic stainless steels ) offers the secondary advantage of a lower material cost.
They fall into 4 subgroups.
1. Fe-Cr-C steels, there were the first grades put into use and still widely used in engineering and in wear resistant applications.
2. Ni-bearing grades, in which Ni replaces some of the C. Compared to the previous group, they offer a higher toughness particularly at low temperatures. Their higher Chromium content leads to a higher corrosion resistance. Molybdenulm additions in groups 1 and 2 improve further the corrosion resistance.
3. Precipitation hardening stainless steels, offer the best combination of strength and toughness.
4. Creep resisting steels, with about 11% chromium, differ from subgroup 1 by additions of Co. Nb,
V and B which increases of high temperature strength and creep resistance up to 650℃.
