All the time corrosion-resistant martensitic They can be hardened by appropriate heat treatment. In practice, they are used, among other things, to produce components requiring increased strength, hardness, or wear resistance. Their corrosion resistance is not the same as 316L austenitic steels.

Martensitic steels and heat treatment
Hardening and tempering affect hardness, impact strength, and corrosion resistance. Mechanical properties cannot be determined solely based on the grade designation without considering the delivery condition and the requirements of the relevant product standard.
Not to be confused with PH
Steel 1.4542 / 17-4PH should be classified separately as precipitation hardened steel, although in certain states it has a martensitic structure. More in comparison of martensitic and PH steels.
