50Mn strength, elasticity and hardness are high, mostly used after quenching and tempering, poor welding performance. 50Mn round steel is used to manufacture heat-treated parts with high wear resistance and high load, such as gears, gear shafts and mandrels with a section below 80mm. The performance is similar to No. 50, Cutting Rule or Creasing Rule but its hardenability is higher, and the strength, hardness and elasticity after heat treatment are slightly higher than that of No. 50 steel. Poor weldability, with overheating sensitivity and tempering brittleness tendency. Used as stress-bearing parts, high-wear parts, high-stress parts, such as mandrel with a diameter of less than 80 mm.Flat Steel For Chain High-frequency quenching can also be manufactured after the train shaft, worm, connecting rod and automobile crankshaft, such as gear, gear shaft, friction disc, spindle, plate spring and so on.
