Steel properties:
Plastic mould steel with additional sulphur, usually supplied in a quenched and tempered condition. Polishable, better machinibility compared to 1.2311. Similar to AISI P20+S.
Process: EAF +LF +VD +ESR +forged or hot rolled + heat treatment (optional)
Surface condition: Black/ round machine/ Turned
Inspection: Ultrasonic test, according to SEP1921D/d or customer requirements
Thermal Treatments
Forging: Heat slowly, allowing sufficient time for the steel to become heated through. Begin forging at 1050° C. Not forge below 930° C reheating if necessary. After forging, cool very slowly.
Stress Relieving: When dies are heavily marchined, recommend stabilishing just before finish machining in order to relieve machining strains. Heat to 460-500° C, Soak well and allow to cool in the air.
Annealing: Heat uniformly to 710-740° C. Soak well, cool slowly in the furnace.
Hardening: Heat to uniformly to until heaeted through. Quench in oil.
Delivery Condition
Forged + Annealed + Machining (Peeled/Turned)
