Forging supplies a variety of semi-finished forged steel products, the main materials are nickel-molybdenum steel, alloy steel, die steel, stainless steel and carbon steel. In addition to 35#, 45#, 42CrMo, 42CrMo4, 18CrNiMo7-6, 20CrNi2Mo, 30CrNiMo8 and other general steel grades, we can also formulate the required steel grades according to other national specifications or specified alloy compositions required by customers. The maximum length/weight of shaft forgings produced is 12m/15T, the maximum diameter/weight of gears and wheel forgings is 1.9m/9T, and we are particularly good at forging special-shaped forgings.
