Martensitic stainless steels are heat treatable alloys for greater hardness and strength.
Heat treatment is critical in determining the mechanical performance of martensitic stainless steel.
Processes such as quenching and tempering significantly influence hardness, toughness, and corrosion resistance.
Proper heat-treatment creates a fully martensitic structure, ensuring high strength and wear resistance,
making the material suitable for demanding mechanical applications.
Our martensitic stainless steel products are supplied in annealed or cold worked conditions for use
in applications that require hardness, high strength and wear resistance, products such as high quality knives,
scissors,measuring tools, food blades, surgical instruments, springs, washers,
mechanical engineering parts, automotive components...
