Grade 440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys.

These tables are intended for estimating purposes only and lists typical chemical properties for a variety of 300 and 400 series stainless steel grades. All values shown indicate the maximum percentage unless otherwise noted. * Stock Grade Technical Data SheetTests have shown that the corrosion resistance of ATI 15-5 precipitation hardening stainless steel is comparable to that of Type 304 stainless steel in most media. In general, the corrosion resistance of ATI 15-5 alloy is superior to that of the hardenable 400 series stainless steels.
- Ferritic Stainless Steel Grade 430Strength of Ferritic Stainless SteelsHardness of Ferritic Stainless SteelsTypes 410, 420, 425 Mod, and 440AFor maximum hardness and strength, a hardening heat treatment is necessary. The stainless steel alloys shown in the table on Page 3 were heated as sheet samples for 60 minutes per inch of thickness at 1800°F (982°C) for Type 410 and at 1900°F (1038°C) for Types 420, 425 Modified, and 440A, and then air cooled to room temperature. The as 400 Series Stainless Steel Overview, Properties, and The 400 series group of stainless steels typically have an 11% chromium and 1% manganese increase, above the 300 series group. This stainless steel series tends to be susceptible to rust and corrosion under some conditions although heat-treating will harden them. The 400 series of stainless steels have a higher carbon content, giving it a martensitic crystalline structure that provides the end product with
