Forging steel is designed for manufacturing forged components including shafts, gears, flanges, fittings, rollers, and heavy machinery parts. We supply forging steel in round bar, square billet, and forged block forms in grades including 42CrMo4, AISI 4140, AISI 4340, 34CrNiMo6, and 40CrNiMoA. These grades offer excellent hardenability, toughness, and fatigue resistance after heat treatment. Material available in forged, rolled, or rough machined conditions with complete metallurgical documentation.
34CrNiMo6 (1.6582) is a high-strength Ni-Cr-Mo alloy forging steel with excellent toughness and deep hardenability. After Q+T, tensile strength reaches 900-1400 MPa. Available as forged round bars (80-1500mm), blocks up to 30T, and rings up to 5m OD for highly stressed shafts, gears, and energy sector components.
