AISI 440C steel is a high carbon chromium stainless steel providing stainless steel properties with optimum hardness after heat treatment. AISI 440C stainless steel can achieve a hardness of up to 60 Rockwell HRc. AISI 440C stainless resists corrosion in normal domestic environments and very mild industrial enviroments, with optimum cossision resistance of 440C achieved with a temper below about 400°C. For 440C to achieve best cossosion resistance, surfaces must be free of scale, lubricants, foreign particles, and coatings applied for drawing and heading. With its high carbon content 440C annealed stainless machines similar to a high speed steel annealed grade.
