Stainless 446 is a high chromium ferritic heat resistant alloy with a high resistance to oxidation, sulfidation and other forms of hot corrosion. It has a high ductile-to-brittle impact transition temperature. 446 is the only heat resistant alloy that will tolerate molten copper and brass.
15-5 is a martensitic precipitation-hardening stainless steel that provides high strength, good corrosion resistance, good mechanical properties at temperatures up to 600°F (316°C) and good toughness in both the longitudinal and transverse directions in both base metal and welds. Alloy 15-5 is the ferrite-free version of Type 17-4 stainless steel. Both alloys are widely used […]
17-7 stainless steel is a stable, chromium-nickel-aluminum precipitation hardened stainless steel that provides high strength and hardness, excellent fatigue properties, moderately resistant to corrosion, good formability, and minimum distortion upon heat treatment.
Of the 400 series of stainless steels, 400C has the highest carbon content and moderate corrosion resistance and can heat-treat to the highest harness of RC 60. (In contrast, 416 is normally heat treated to RC 26/32)
