EF + LF + VD Ship Forged Steel Shaft ASTM EN DIN GB , Hot Roll / Cold Roll Shaft Forging
Forged alloy steel rolls;forging white cast iron rolls, bending rollers, hot roll, cold roll, backup roll
Gear shaft, pinion shaft, gear axle, shaft forging
Quick Detail:
1. Forged alloy steel rolls; forged steel rolls half; forging semi-high speed steel rolls; forging white cast iron
rolls, bending rollers, hot roll, cold roll, backup roll.
2. Common cold roll rolls of material to work there 9Cr, 9Cr2, 9Crv, 8CrMoV so cold roll requires surface
hardening, hardness HS45 ~ 105. Hot roll commonly used materials 55Mn2, 55Cr, 60CrMnMo, 60SiMnMo etc.
3. Mature production capacity, good quality, good service, short delivery time
