Q690C steel plates are mainly used in heavy machinery, marine engineering, metal structures. BBN STEEL cooperated with Wugang to produce Q690C steel for use in its enterprise production and construction projects. The prospects for produts exporting to the United States, Canada, Australia, India, and Europe are promising. More than 10,000 tons A588 Grade B tempered and quenched steel products have been directly supplied to European customers.
A588 Grade B tempered and quenched steel, St52-3 steel is a low alloy, high strength structural steel which can be readily welded to other weldable steel. St52-3 steel’s mechanical properties is yield strength more than 355 MPa, tensile strength 490-630Mpa. For St52-3 steel, the C element content is 0.24%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.045% max, the S element content is 0.045% max.
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 A588 Grade B tempered and quenched steel 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.
