Product Description

 

Product Description

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.

Features and applications

Quenched and tempered steel, after quenching and high temperature tempering, has high tensile strength and yield strength, and can obtain fine grain structure. Its comprehensive mechanical properties are better than 40Cr steel. However, when the quenching temperature is not enough, the hardenability is poor. The cold deformation plasticity and machinability are medium, and the overheating sensitivity is small, but there is a tendency of temper brittleness and white spot sensitivity. It is generally used in the quenched and tempered state. It is used to manufacture various important parts with variable load and high load, such as locomotive connecting rod, crankshaft, push rod, propeller, cross beam, shaft sleeve bracket, stud, screw, non carburized gear, various gears and pins after nitriding treatment, high-pressure boiler water pump shaft (diameter less than 30mm), high-pressure cylinder, steel pipe and bolt (working temperature less than 420 ºC, 30MPa), etc. As tool steel, the steel can be used to make high-end hand tools, hardware tools, etc.
