Short Description:
China Wholesale Hot Rolled Seamless Pipe Sch40 Manufacturers - Q355d steel plate – Wenyue Detail:
Thickness
The steel grade of thick steel plate is basically the same as that of thin steel plate. In terms of products, in addition to bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, some varieties of steel plates, such as automobile girder steel plate (2.5 ~ 10mm thick), checkered steel plate (2.5 ~ 8mm thick), stainless steel plate, heat-resistant steel plate and other varieties are crossed with thin plates.
In addition, the steel plate also has material. Not all steel plates are the same. The material is different, and the place where the steel plate is used is also different.
Properties of alloy steel
With the development of science, technology and industry, higher requirements are put forward for materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion, wear and other special physical and chemical properties. Carbon steel can not fully meet the requirements.
Deficiency of carbon steel:
(1) Low hardenability. In general, the maximum diameter of water quenched carbon steel is only 10mm-20mm.
(2) The strength and yield strength are relatively low. Such as ordinary carbon steel and Q235 steel σ S is 235mpa, while low alloy structural steel 16Mn σ S is more than 360MPa. 40 steel σ s / σ B is only 0.43, much lower than that of alloy steel.
(3) Poor tempering stability. Due to the poor tempering stability, when the carbon steel is quenched and tempered, it is necessary to adopt a lower tempering temperature in order to ensure higher strength, so the toughness of the steel is low; In order to ensure better toughness, the strength is low when high tempering temperature is adopted, so the comprehensive mechanical property level of carbon steel is not high.
(4) It cannot meet the requirements of special performance. Carbon steel is often poor in oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic properties, which can not meet the needs of special performance.
