In addition to iron and carbon, other alloy elements are added to alloy steel, which is called alloy steel. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. According to the different added elements and adopting appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance and non-magnetism can be obtained.

15Cr/1.7015/15Cr3/
5115/G51150/ SCr415 |
It is used to manufacture various carburized parts with high surface wear resistance, high core strength and toughness, high
working speed, but section size below 30mm, such as crank pin, piston pin, piston ring, coupling, small camshaft, pinion, slide valve, piston, bushing, bearing ring, screw, rivet, etc. It can also be used as quenched steel, manufacturing small parts with certain strength and toughness, but wide deformation requirements |
|
20Cr/A20202/20X/SCr420/5120 l/20Cr4
|
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) |

One of the most widely used steel grades of Zui is used to manufacture medium-speed and medium-load parts after quenching and
tempering, such as machine tool gears, shafts, worms, spline shafts, thimble sleeves, 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 gears, shafts, spindles, crankshafts, mandrels, sleeves, pins, connecting rods, screws, nuts, inlet valves, 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, sliding block, gear, main shaft, collar, etc., after quenching and low temperature tempering, it is used to manufacture heavy load, low impact, wear-resistant parts, such as worm, main shaft, shaft, collar, etc., after carbonitriding treatment Make transmission parts with large size and high low-temperature impact toughness, such as shafts and gears. The 40Cr substitute steels include 40MnB, 45MnB, 35SiNn, 42SiMn, 40MnVB, 42MnV, 40MnMoB, 40MnWB, etc |
