440C stainless steel is a member of the 400 series of stainless steels. It has the highest carbon content of all the stainless steel alloys and is hardened by heat treatment. 440C offers high strength, hardness, and excellent wear resistance. It’s often used in high-wear applications like cutlery, bearings and races, bushings, valve components, surgical instruments, and molds and dies. This stainless steel is not recommended for use at high temperatures (typically higher than 400°C) to avoid reduction of its corrosion and impact resistance.

Commercial use of the alloy is governed by industry standards such as: AMS 5618 (VAR), AMS 5630, AMS 5880, ASTM A276, AMS QQ-S-763, ASTM A493, ASTM A580, DIN 1.4125, BS EN 10088.
Because of 440C’s high strength, hardness and wear resistance, this stainless steel is often used in high-wear applications like:
- Gage Blocks and Measuring Instruments
- Cutlery (Knives, Forks, Spoons)
- Ball Bearings and Races
- Molds and Dies
- Surgical Instruments
