This heat treatable martensitic, nickel-bearing grade has the best corrosion resistance properties of all the martensitic grades.
It has excellent tensile and torque strength, and good toughness, making it ideally suited to shafting and bolt applications.
It can be hardened to approximately 40HRC. Because of its high yield strength, this grade is not readily cold worked and is therefore not recommended for use in operations such as cold heading, bending, deep drawing or spinning.
Martensitic stainless steels are optimised for high hardness, and other properties are to some degree compromised.
Fabrication must be by methods that allow for poor weldability and usually also allow for a final harden and temper heat treatment. Corrosion resistance is generally lower than the common austenitic grades, and their useful operating temperature range
is limited by their loss of ductility at sub-zero temperatures and loss of strength by over-tempering at elevated temperatures.
