GB\/T8162 Seamless Steel Pipe Description<\/strong><\/b><\/h2>\n

GB\/T8162\u00a0is a\u00a0standard seamless pipe, suitable for seamless pipes in general structures and mechanical structures.\u00a0The parts after quenching and tempering of\u00a0GB\/T8162\u00a0seamless steel pipe have good comprehensive mechanical properties and are widely used in various important structural parts, especially those connecting rods, bolts, gears and shafts that work under alternating loads. However, the surface hardness is low and not wear-resistant. Quenching and tempering, as well as surface quenching can be used to improve the surface hardness of the parts.<\/p>\n
