Astm 5120h Steel Plate Forging Common Defects And Preventive Measures - China

Common defects and preventive measures of ASTM 5120H Steel Plate

Surface cracks: The final forging temperature is too low and the deformation is too large, so the final forging temperature must be ≥850℃ and the single deformation must be controlled ≤40% Internal cracks: ASTM 5120H Steel Plate The heating speed is too fast and the core of the billet is not heated through.

Extend the preheating time to ensure uniform temperature inside and outside the billet Coarse grains: The heating temperature is too high or the insulation time is too long, so the initial forging temperature must be strictly controlled to be ≤1150℃ to avoid long-term high temperature stay Oxidation decarburization: The atmosphere in the heating furnace is highly oxidizing, so use less or no oxidation heating (such as controlling the carbon potential in the furnace or introducing protective gas) Songshun Company Website:
