Rubber Mold Steels
PX5
- Welding
Superior mold quality after welding. Low hardness of heat affected zone eases
post-weld cutting and grinding operations and minimizes mold distortion, etch
unevenness, and differences in luster upon mirror finishing. Unique
composition eliminates weld cracking.
- Machining
Rough machines up to 50% faster than P20 (30% overall) to a superior surface
with negligible dimensional change. Use of PX5 assures the longest cutting
tool life of any 30 HRc, P20-type material. Consistent hardness and
microstructure allow dependable, unattended machining.
- EDM
EDM surface hardness is about 70% of that produced by typical P20-type steels.
Post EDM grinding and polishing operations are simpler and more consistent,
and problems such as surface layer cracking or peeling are reduced.
- Stability
Uniform hardness and refined grain structure assure the highest level of
dimensional stability (after machining) of any P20-type mold steel.
- Surface Enhancements
Can be ion-nitrided to produce a surface hardness over 60 HRc with negligible
distortion or dimensional change.
- Texturing and Polishing
Uniform microstructure and hardness give PX5 the best surface-finish
characteristics of any P20-type material. Low chemical segregation eliminates
the occurrence of photo etch unevenness.
- Toughness
Exceptional toughness reduces cracking problems in molds
