What is the BBN Steel JIS SM490C plates quotation

Steel pipe refers to the steel with openings at both ends and hollow section, and its length is larger than that of surrounding steel. According to the processing technology, it can be divided into seamless steel pipe and welded steel pipe, JIS SM490C plates. The production methods mainly include hot rolling, cold rolling, extrusion, cold drawing, forging, welding, etc. The size range of steel pipe is very wide, from capillary with small diameter to large diameter pipe with several meters. Steel pipe can be used for pipeline, thermal equipment, mechanical industry, petroleum geological exploration, container, chemical industry and special purpose.

The company specializes in producing high-strength low-temperature resistant low alloy plates Q345C, Q345D, Q345E, SM400, JIS SM490C plates, SM490, S355J2 + N;bridge plates Q345qC / qD / qE, Q370qE high-strength structural plates, etc. Z-direction performance (Z15, Z25, Z35). Above materials have high yield strength, high tensile strength, Brinell hardness, and Rockwell hardness; and low temperature resistance, they also can be maintained at high temperatures of -60 ℃.

We have a stable system and professional human resource management work as the support, from the six aspects of guidance, cohesion, incentive, constraint, radiation and stability, we continue to introduce, modify and train employees from concept to action, and shape employees through constant guidance of common values.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as JIS SM490C plates. 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.
