Martensitic Stainless Steels — Materials Technology

Martensitic stainless steels optimized for razor blade applications are balanced to give an extremely fine dispersion of carbides in the delivery condition (Figure 3). This facilitates the dissolution of carbides during heat treatment and liberates enough carbon to make the martensite sufficiently hard.

Article: Martensitic Stainless Steels - bssa.uk

Martensitic stainless steels are similar to low alloy or carbon steels. They have a structure similar to the ferritics with a 'body-centred tetragonal' (bct) crystal lattice. Due to the addition of carbon, they can be hardened and strengthened by heat treatment, in a similar way to carbon steels.

What is the difference between austenitic, ferritic, and ...

These terms refer to the crystal structure of the metal. Regular steel (non-stainless) would be considered "ferritic" because the room-temperature microstructure is comprised of a mix of ferrite and pearlite. Ferrite is soft and ductile, while pearlite is hard and brittle. As the overall content of carbon increases, the proportion of pearlite becomes higher andRead more
