Steel Forging Workflow (Simplified)
Raw material verification → Section cutting → Uniform preheating under controlled temperature → Open die forging followed by heat treatment → Preliminary quality check of forged blanks → Rough machining for dimensional shaping → Non-destructive testing (UT/MT) and hardness measurement → Quenching and tempering for mechanical strength → Comprehensive final inspection → Precision finish machining → Product identification, marking, and protective packing → Warehousing and delivery to customer
