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.
