The boiler steel pipe has excellent anti-oxidation and corrosion performance: the general steel pipe is easy to be corroded under high temperature and produces harmful substances, but the boiler steel pipe has no such worries. The high-precision material and wall thickness of the boiler steel pipe can effectively prevent the corrosion. Good tensile strength of differences between a573 gr.70 and a515 gr.70 steel, boiler steel pipe: it can keep the original state well without affecting its quality after being heated and stretched.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the differences between a573 gr.70 and a515 gr.70 steel quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After differences between a573 gr.70 and a515 gr.70 steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our differences between a573 gr.70 and a515 gr.70 steel office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase differences between a573 gr.70 and a515 gr.70 steel 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.
