Classification
Type Characteristics Applications
SUS
(JIS)
NSS
High Tensile
Type
(including precipitation hardening type)
  HT980
High strength can be obtained by quench hardening at 750℃ or higher temperatures.
steel belts,
high tension materials for welding
(632J1) HT1770
Workable at low hardnesses because of high hardenability obtainable with age-hardening.High workability and long mold life.
seat sensor parts,
punched springs
  HT1770M
High toughness,high strength and high fatigue strength can be obtained by adding molybdenum.
steel belts,
golf club head
  HT2000
High strength with ductility,toughness and fatigue strength.
ID saw blade,
flapper valve
Dual-phase
Type
  431DP2
Spring characteristics can be obtained by a short-time age-hardening.
automotive parts,
wrapping carrier,
press plate
