1.6582 Steel| DIN 1.6582 | 34CrNiMo6

WALDUN is one of the best 1.6582 steel Manufacturers and Exporters from China, supplied with round,square,flat,block,and shaft etc. DIN 1.6582/34CrNiMo6 a heat treatable, low alloy steel which contains  chromium,molybdenum and nickel as strengthening agents as per BS EN 10083-3:2006. It is known for its good strength,toughness, hardenability and capability of developing high strength in the heat treated condition while retaining good fatigue strength,but it is poor in weldability,usually this steel should be hardened and tempered before application.

1.6582 steel is used for the requirement of high strength, high toughness, large cross-sectional size and more important tempered parts, such as the drive eccentric shaft of horizontal forging machine, forging press crankshaft, etc.. Used after tempering, used to make important parts requiring good plasticity, high strength and large size. If the heavy machinery in the high load of the shaft, diameter greater than 250mm turbine shaft, blade, high load of transmission parts, fasteners, crankshaft, gears, etc.. In addition, nitriding treatment can also be used to make important parts with special performance requirements.
