Characteristics

SUS630-S

  • Chemical composition is within JIS standard of SUS630 and modified to improve cold workability and machinability under solution heat treatment condition.
  • Compression property is 15~20% lower than SUS630 regarding stress-strain.
  • Hardness and corrosion resistance after precipitation hardening treatment is equivalent to SUS630.

DSP1H

  • High hardness is achieved by short precipitation hardening treatment.
  • Corrosion resistance is better than SUS420J2, lesser than SUS630.
  • Cold work hardening property is less and it is available for cold header.
