ASTM A285M GR.B Black Seamless Steel Tube

The main use of alloy steel pipes is for high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters and reheaters. Made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. , after hot rolling (extrusion, expansion) or cold rolling (stretching). Alloy steel pipe is a kind of seamless steel pipe, and its performance is much higher than that of general seamless steel pipe, because this steel pipe contains Cr, and its high temperature resistance, low temperature resistance, corrosion resistance and other properties are unmatched by other non-pipe joints. It is more widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries.
