Choosing the right steel for the job
Grade Application
Alu-c Cast Aluminium-special heat treatment to enhance stability and machinability
Alu-x Forged Aluminium-largest sizes available – highly polishable
4140 Lower cost mould application or mould bases
HB Holder block free machining for mould bases
Mold Die Higher hardness Core and cavity – consistent reprodducibility in texturing& polishing (P-20)
Mold Die Premtum Vacuum Arc Remelted Mold Die – lens quality P-20
Hi-Hard (P-20) Long run core and cavity – with the same reproducibility as Mold Die
LR Super long run core and cavity, not needing perfect mirror finish
DC High hardness, long run moulds(H-13)
DC-Xtra Premtum Vacuum Arc Remelted DC–lens quality
DCF Strong , heat resistant , free machining , pre-hardened to 43-47 HRc
420M 420 Stainless steel mold – Molybdenum modified for increased corrosion
resistance
420MB 420 Stainless steel – free machining – mould base
420M Premium Vacuum Arc Eomelted 420M – lens quality
Mar-X Corrosion resistant,precipitation hardening,very stable,lens quality
DRX High quality shock resistant tool steel(S7)
CupreX Machines 2-3 times faster than P-20.Longer runs than aluminium,greater
thermal conducrivity than P-20
TVX Corrosion resistant-great for long run glass/plastic molds
RA-40 Premium Weldable.machinable,precipitation hardening(40 HRc)
| HOT WORKING DIE STEELS/RAMS/PISTON RODS,ETC |
CX Very ductile,great for warm and precision forging
EX An excellent overall steel –a perfectly balanced Ni-Cr–Mo alloy
WF One of the best,long run die steels produced in the world
Shell Die Super heat and wear resistance-excellent for reverse extruders(h-11)
DC Super heat and wear resistance –press applications(H-13)
ShelleX Better wear,tempering and thermal fatigue resistance than H-11 or H-13
Press Die Precipiutation hardening –great for presses or upsetting
with long dwell
times
| PRESSURE DIE CASTING DIE STEELS |
Shell Die Heat and wear resistant
Shell Die premium Vacuum Arc Remelted shell Die
DC Heat and wear resistant
DCF Strong ,heat resistant ,free machining,pre-hardened to 43-47HRc
DC-Xtra Premium Vacuum Arc Remelted DC-better thermal fatigue resistance than H-11 or H-13
ShelleX Better wear ,tempering and thermal fatigue resistance than H-11 or H-13
ShelleX Premfum Vacuum Arc Remelted shelleX-tougher and cleaner than H-11 or H-13
