We can do large diameter forged steel disc. The OD is from 120mm-1500mm.
The forged disc can be manufactured as per customers' drawings. And our technologists also can design the drawings for customers.
Quality first is our principle. Our national level II lab can control the quality( chemical composition inspection, mechanical properties inspection,hardness inspection.
Forged Steel Disc
Our forged steel disc is made of material 826M40， 30CrNiMo8 .
Materials can be as per customers' requirement.
