| ASTM 5115 GB 15Cr | It can be used to manufacture various carburized parts with high surface wear resistance, high core strength and toughness, high working speed but less than 30mm section size, such as crank pin, piston pin, piston ring, coupling, small camshaft, pinion, slide valve, piston, bushing, bearing ring, screw, rivet, etc., and can also be used as hardened steel. It can also be used to manufacture small parts with certain strength and toughness, but wide deformation requirements. |
| ASTM 5120 GB 20Cr | It is used to manufacture various carburized or carbonitriding parts with small section (less than 30mm), simple shape, high speed, small load, surface wear resistance and high core strength, such as pinion, pinion, valve, piston pin, bushing ratchet, tray, cam, worm, tooth clutch, etc. For parts with small heat treatment deformation and high wear resistance requirements, general quenching or high-frequency quenching shall be carried out after carburizing, such as small module (less than 3mm) gear Spline shaft, shaft, etc. can also be used as quenched and tempered steel for manufacturing parts with low speed and medium load (impact). |
| ASTM 5130 GB 30Cr | It is used to manufacture various wear-resistant or impacted parts, such as gears, rollers, shafts, levers, rocker rods, connecting rods, bolts, nuts, etc. It can also be used as high-frequency surface hardening steel to manufacture wear-resistant and high-hardness parts. |
| ASTM 5135 5132 GB 35Cr | It is used for manufacturing gears, shafts, rollers, bolts and other important quenched and tempered parts. Its purpose is basically the same as that of 5130. |
| ASTM 5140 GB 40Cr | After quenching and tempering, it is used to manufacture parts with medium speed and medium load, such as machine tool gear, shaft, worm, spline shaft, thimble sleeve, etc. After quenching and tempering and high-frequency surface quenching, it is used to manufacture parts with high surface hardness and wear resistance, such as gear, shaft, main shaft, crankshaft, mandrel, sleeve, pin, connecting rod, screw, nut, intake valve, etc. After quenching and medium temperature tempering, it is used to manufacture parts with heavy load and medium speed impact, such as oil pump rotor, slide Gears, spindles, collars, etc. are used to manufacture heavy-duty, low-impact and wear-resistant parts after quenching and low-temperature tempering, such as worms, spindles, shafts, collars, etc. After carbonitriding treatment, transmission parts with large size and high low-temperature impact toughness, such as shafts, gears, etc. |
| ASTM 5145 GB 45Cr | Similar to 5140, it is mainly used for manufacturing high-frequency surface hardened shafts, gears, sleeves, pins, etc. |
| ASTM 5150 GB 50Cr | It is used to manufacture heavy-duty and wear-resistant parts, such as hot-rolled rolls, transmission shafts, gears, thrust rings below 600mm, mandrels of backup rolls, connecting rods and tappets of diesel engines, tractor clutches and bolts, wear-resistant and high-strength oil film bearing sleeves and gears in heavy mining machinery, as well as high-frequency surface-hardened parts, moderately elastic springs, etc. |
