440C stainless steel is a member of the 400 series of stainless steels. It has the highest carbon content among them. The standout properties of this type of steel are its hardness, mechanical strength and fatigue resistance. This combination of properties makes it useful in the production of cutting tools. Due to its high carbon content, it does not have outstanding corrosion resistance, but it can still be used for applications that require moderate corrosion resistance such as surgical instruments.
440C stainless steels typically have a composition of 78 – 83.1% iron, 16 – 18% chromium, 1 – 1.2% carbon, 1% (max) silicon, 1% (max) manganese, 0.8% molybdenum, 0.04% phosphorus and 0.02% sulphur. They have a martensitic grain structure, and they are primarily hardened through solid solution strengthening with chromium and precipitation hardening of molybdenum carbides

-
Excellent resistance to corrosion, including:
-
Pitting corrosion
-
Crevice corrosion
-
Stress corrosion cracking
-
-
Strong performance in chloride-rich and sour environments
-
Chromium: ~24–26%
-
Nickel: ~6–8%
-
Molybdenum: ~3–4%
