 Edit properties of this paragraph 
 50Mn strength, flexibility and hardness were higher than in the quenched and tempered use, welding performance is poor. 50Mn demanding round for the manufacture of wear resistance, high heat load under the action of parts such as gears, gear shaft and the cross section below the spindle in 80mm and so on. Performance with 50 similar, but its high hardenability, strength after heat treatment. Hardness elasticity are slightly higher than the 50 steel. Poor welding, heat-sensitive and has a tendency to temper brittleness. Withstand the stress components for High wear-resistant parts, high stress parts, such as less than 80 mm diameter mandrel. After quenching can also create high-frequency train shaft, worm, and automotive crankshaft connecting rod, such as gears. Gear shaft friction disc. Spindles. Flat springs.
