Martensitic stainless steel is a versatile steel that has many practical uses for various industries. This type of steel is very responsive to multiple forms of heat treatment that can increase strength, hardness, and corrosion resistance. Martensitic stainless steel's strength and corrosion resistance can be ideal for marine, industrial, and ...

Martensitic stainless steel has higher carbon content (0.12% to 0.35%) and lower nickel content than austenitic stainless steel, resulting in increased hardness and strength. Although its corrosion resistance is lower than other grades of stainless-steels, it finds diverse applications across various industries.

Martensitic transformation. Martensitic transformation of shape memory alloys is a shear-like mechanism which takes place below the transition temperature. The martensitic transformation can be induced by mechanical forces or by temperature changes in a cooling process.

Martensitic stainless steels typically contain between 11.5 to 18% chromium, up to 1% carbon, and other elements, such as nickel, selenium, phosphorus, vanadium, and sulphur are added in different grades to achieve specific properties. These steels have a face-centred cubic (FCC) structure at high tempe…

The areas of use of martensitic and martensitic–austenitic steels are naturally those in which the high strength is an advantage and the corrosion requirements are relatively low. The martensitic steels with low carbon contents and the martensitic–austenitic steels are often used as stainless constructional materials. The martensitic steels with high …

This paper reviews the strengthening mechanisms associated with the various components of martensitic microstructures in steels and other ferrous alloys. The first section examines the experiments and strengthening theories associated with Fe–Ni and Fe–Ni–C alloys, in which the martensite, because of subzero Ms temperatures, can be evaluated with …
