High Carbon AISI 440C Stainless Steel Sheet And Plate UNS S44004

AISI 440A/440B/440C EN 1.4109/1.4112/1.4125 UNS S44002/S44003/S44004

The 440 grades form a series of high carbon martensitic stainless steels.

They have basic corrosion resistance and extremely high hardness and wear resistance.

Approximate Composition – 16% Cr, 0.60-1.0% C plus Mo and V in EN grades.

This grade combines the following characteristics:

  • Basic corrosion resistance. Lower than other martensitic grades like 431
  • Very high hardness increasing with carbon content. 440C capable of 60 Rockwell HRC (~700 HV)
  • Very high strength up to 2000 MPa UTS, 1900 MPa 0.2% PS
  • Low elongation 4%
  • Low toughness 10J
  • Very high wear resistance
  • Difficult to weld
  • Difficult to machine

This series of grades give the highest level of strength/hardness in any martensitic stainless steel.

Consequently, they are used where a basic level of corrosion resistance is required coupled with high

wear resistance or blade sharpness. They are usually supplied in the annealed condition for improved

machinability and then hardened and tempered to develop the high hardness.

Applications which illustrate these features include:
Bearings, valves, knife blades, surgical instruments, tools, moulds, dies.

Composition of stainless 440C ( Nominal )
0.95/1.20 C, 1.00 Mn, 0.040 P, 0.030 S, 1.00 Si, 16.00/18.00 Cr, 0.75 Mo, Bal. Fe

Type 440C is capable of attaining very high hardness; approximately Rockwell C 60.

This stainless principally has been used in bearing assemblies, including bearing balls and races.
