 40CrNiMoA 
 Alloy structural steel referred to as structural steel, 40CrNiMoA is one of structural steel, also known as alloy steel, which is high-quality carbon structural steel, based on the appropriate join one or more alloying elements (total content of not more than 5%) and made of steel. Bearing parts after heat treatment common quality defects are: quenched microstructures overheating, due to heat, quenching cracks, hardness is not enough, heat deformation, surface decarburization, soft points. 
 Implementation of standards GB/T3077-1999. 
 Unified digital code A50403; 
 Grades 40CrNiMoA; 
 Chemical composition (%): 
 Carbon C: 0.37 ~ 0.44 
 Si Si: 0.17 ~ 0.37

 Sample size: Sample size is 25mm rough 
 Heat treatment: (quenching 850 degrees; cooling agent: oil; tempering temperature of 600 degrees; coolant: water, oil); 
 High-temperature annealing or tempering of steel supply status Brinell hardness GBW ≤ 269; 
 Delivery status: to heat treatment (normalizing, annealing, or tempering) or heat treatment delivery, delivery status should be indicated in the contract. 
 Uses: used for high strength, high toughness, cross-section of a larger size and more important conditioning parts, such as horizontal forging machine drive eccentric shaft, forging press 
 Crankshaft. Quenched after use, requirements for the production of plastic, high strength and large size of the important parts. If the high load of heavy machinery in the shaft, turbine shaft diameter greater than 250mm, blade, high-load transmission parts, fasteners, crankshaft, gears, etc. In addition, nitriding treatment can be used to make specific performance of the important parts.
