Martensitics stainless steels

• Carbon high level included between 0,10% and 1%
• Chromium modest content between 11,5% and 18%
• High mechanic characteristics: this is the only steel that can be quenched, the thermal treatment that increases the values of braking lead, yield strength, and hardness.
• It has good aptitude for plastic deformation
• It has poor resistance to corrosion due to the low "free" chromium content, which is responsible for the formation of the protective oxide.
• Magnetic

At UBB, we have recently realized a self-drilling screw in martensitic steel with hexagonal head for iron AISI 410 (1.4021) 6,3x19 with heat-treat and superficial coating GEOMET 321 A for the field of industrial refrigeration (HVAC & R).
