Factory

Production Technology

Process Type	Specific Process Description
Hot Working	Forging temperature: 870–1175 °C Avoid working in low temperatures and high-sulfur environments to prevent hot brittleness
Cold Working	Applicable processes: cold rolling, cold drawing, cold forging Intermediate annealing (870–980 °C) is required to eliminate work hardening
Machining	Use carbide cutting tools, low speed and high feed rate Cutting fluid lubrication is recommended to avoid tool sticking
Welding	Recommended methods: TIG (GTAW), MIG (GMAW), Shielded Metal Arc Welding (SMAW) Filler metal: ERNiCu-7 (AWS A5.14) Preheat to 150–200 °C for large cross-section welding
Heat Treatment	Annealing: 870–980 °C, rapid cooling (water quench or air cool) Stress relieving: 510–650 °C, slow cooling
Other Processes	Grinding: suitable for precision machining Polishing: electro-polishing to improve corrosion resistance
