50Mn high elastic carbon structural steel plate is used to manufacture heat-treated parts with high wear resistance requirements and under high load, such as gears, gear shafts and mandrels with a cross-section below 80mm. The performance is similar to that of No. 50, but its hardenability is higher, and the strength, hardness and elasticity after heat treatment are slightly higher than that of No. 50 steel.

          Weldability is poor, and it has a tendency to overheat sensitivity and temper brittleness. Used as stress-bearing parts. Highly wear-resistant parts, high-stress parts, such as mandrels with a diameter of less than 80 mm. After high-frequency quenching, it can also manufacture train shafts, worms, connecting rods and automobile crankshafts, such as gears, gear shafts, friction discs, spindles, flat springs, etc.
