SW4Cr13ESR Corrosion Resistant Plastic Mold Steel
Manufacturing Process
EAF → LF-VD → Hydrogen protection ingot casting → Electroslag metallurgy → Multi-directional forging → Heat treatment → Ultrasonic flaw detection → Finished product inspection and storage
Product Features
Electroslag process produces high purity, low impurity content, fine structure and uniform hardness
Excellent rust and acid resistance, high hardenability, excellent polishing and wear resistance
Excellent dimensional stability during quenching
Delivered in spheroidized (soft fire) state, excellent processing performance
Product Use
Plastic molds with high requirements for corrosion resistance and rust resistance, such as PVC pipe fittings and other corrosive plastic injection molds and compression molds.
Injection molding materials with high requirements for mold wear resistance and fatigue resistance, such as thermosetting injection molding molds with large wear during use or electronic parts, food packaging and medical equipment molds that work for a long time.
Injection molding and blow molding molds with high surface quality requirements, such as optical products, transparent parts molds, etc.
