• Friction components.
• Cutting blades in corrosive environments.
• Surgical instruments.
• Mould components for synthetic material processing.
• Martensitic stainless steel combining remarkable corrosion resistance, a high level of hardness, very good abrasion resistance and excellent cutting properties.
• Treatments including tempering at 180°C are recommended to obtain maximum resistance to corrosion. Treatments including double tempering at 500°C are used for hot applications or in case of surface treatments involving a rise in temperature of up to 500°C.
• From some applications the steel may be core treated to obtain a strength of 900 to 1200N/mm2 with the aim of subsequently undergoing induction surface hardening to obtain 59HRC.
