Forged steel shafts are use in industry, such as forging equipment; power plant equipment; hydraulic equipment; rolling mill equipment; petroleum machinery, etc.
The production process as "EF + (LF) + (VD) + ESR + forging and annealing (or normalizing) + heat treatment (quenching and tempering) + Machining + packaging + delivery. "
Quality control: chemical analysis, optical spectrum instrument, Mechanical properties for tensile strength, yield stress and elongation. Hardness testing, impact testing, coordinate measuring machine (CMM), metallographic analysis, magnetic flaw detector, Ultrasonic flaw detector.
