Chemical composition % of the ladle analysis of grade 440C Stainless Steel and Standards
Type 440C Stainless Steel provides the ability to achieve and maintain exceptional hardness and wear resistance as well as good strength and moderate resistance to corrosion. On the Rockwell C hardness scale, type 440C Stainless Steel measures between 58 and 65. Due to these advantages, alloy 440C is most often used in ball bearings and races, gauge blocks, molds and dies, valve components, knives, cutlery, and measuring instruments. It is recommended to machine type 440C Stainless Steel in its annealed condition with carbide or ceramic tools. It is not typically welded as it is prone to air hardening. If welding is necessary, the work piece must be preheated to 500° F. After welding, treat the metal for 6 hours at a temperature between 1350° F and 1400° F. Then, to avert cracking, the stainless steel must be furnace cooled slowly. Stainless Steel alloy 440C stainless steel can only be marginally cold worked. When hot working, the metal must be kept at a temperature above 1700° F. Before beginning hot working, preheat the material to 1400° F and gradually increase to a temperature between 1900° F and 2200° F. After hot working, cool the work piece slowly until it reaches room temperature and then fully anneal it.

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
