440C UNS S44004 stainless steel bar with hardness up to HRC60

  • 440C related specifications:
    • The US: ASTM A276-98b 440C/SAE 51440C AISI 440C/UNS S44004
    • Germany: W.Nr 1.4125 X105CrMo17
    • Japan: JIS G4303 SuS 440C
    • Australia: AS 2837-1986 440C
  • Overview of 440C stainless steel:
    • 440C stainless steel is a type of modern steel and famous for its high corrosion resistant, wear resistance, strength and hardness qualities, among all the stainless alloys, capable of attaining (after heat treatment) the highest hardness (60 HRC)
    • It has good resistance to the atmosphere, fresh water and mild acids
    • It has best resistance in the hardened, tempered and passivated condition
    • It allows creating a smooth polished surface and razor sharp edges
    • It is being used in cutting instruments, rolling element bearings, valve seats, high quality knife blades, surgical instruments, chisels, ball bearings and valve parts and most commonly used in the production of cutting tools, including haircutting scissors, daggers and swords
    • Grades 440A and 440B are identical except for slightly lower carbon contents (0.60 - 0.75% and 0.75 - 0.95% respectively), they attain lower hardness but have slightly higher corrosion resistances
    • Although all three versions of this grade are standard grades, in practice 440C is more available than the A or B variants
  • Applications of 440C stainless steel:
    • Ball bearings
    • Knives
    • Mold inserts
    • Nozzles
    • Surgical tools
    • Valves
    • Wear parts of pumps
