High strength, good elasticity, low cold deformation plasticity, medium machinability, poor weldability, no temper brittleness, low hardenability, easy to produce cracks during water quenching. It is usually used after normalizing, tempering after quenching, or high-frequency induction quenching. Used as mechanical parts with high wear resistance requirements and small dynamic load and impact effects, such as forged gears, pull rods, rollers, shaft friction discs, machine tool spindles, engine crankshafts, agricultural machinery plowshares, heavy load mandrels, etc., as well as less important damping springs, spring washers, etc

| 50 | High strength medium carbon structural steel has low cold deformation ability and medium machinability. Poor weldability, no temper brittleness, low hardenability, easy to crack during water quenching. Use status: normalizing, tempering after quenching, high-frequency surface quenching, applicable to mechanical parts with high wear resistance under the condition of small dynamic load and impact | Forged gears, pull rods, rollers, shaft friction discs, machine tool spindles, engine crankshafts, agricultural machinery ploughshares, heavy load mandrels and various shaft parts, as well as minor damping springs, spring washers, etc |
| 55 | It has high strength and hardness, poor plasticity and toughness, medium machinability, poor weldability, poor hardenability, and easy to crack when water quenched. It is mostly used after normalizing or tempering treatment, and is suitable for manufacturing high-strength, high-elastic and high-wear parts | Gear, connecting rod, wheel rim, rim, locomotive wheel rim, flat spring, hot rolling roller, etc |
| 60 | It has high strength, high hardness and high elasticity. During cold deformation, the plasticity is poor, the machinability is medium, the weldability is poor, the hardenability is poor, and the water quenching is easy to crack; Therefore, large parts shall be normalized. | Roll, shaft, wheel rim, spring coil, damping spring, clutch, wire rope |
