JIS carbon steel SM400A CS plate temper embrittlement

Q460 means that the plastic deformation will occur when the stress strength of steel reaches 460 MPa, that is, when the external force is released, the steel can only maintain the stress shape and can not return to the original shape, which is higher than the general steel. JIS carbon steel SM400A CS plate, Q460 steel grades include Q460C, Q460NC, Q460ND, Q460NE, Q460MC, Q460MD, Q460ME.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products JIS carbon steel SM400A CS plate are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

The company's business philosophy: customer satisfaction is the most important measure of our work performance; employees are the company's most important wealth; the improvement of employees' quality and professional knowledge is the growth of the company's wealth; employees' welfare and living standards are the concrete embodiment of the company's business performance; product and service quality are the lifeblood of the company's development; brand is the company's products and A mirror of service; recognition of the market is the foundation of the company's survival.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as JIS carbon steel SM400A CS plate. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.
