Product description:

Hot-rolled and cold rolled seamless steel pipe points (written) seamless steel categories. Hot-rolled steel Steel tube sub-normal, low, medium pressure boiler pipe, high pressure boiler pipe, steel pipe, stainless steel pipe, oil cracking pipe, steel and other steel and other geological. Cold-rolled (allocated) seamless In addition to sub-general steel pipe, low pressure boiler pipe, high pressure boiler pipe, steel pipe, stainless steel pipe, oil cracking pipe, the other steel, but also includes carbon thin-walled steel, alloy thin-walled steel pipe, thin-walled stainless steel, special steel, hot rolled seamless pipe diameter is generally greater than 32mm, wall thickness 2.5-75mm, cold-rolled seamless steel pipe diameter can go to 6mm, wall thickness can be 0.25mm, outer diameter thin-walled tube to 5mm, wall thickness less than 0.25 mm, cold-rolled high dimensional accuracy than hot-rolled seamless steel pipe for general use: with 1,020,303,545 other high-quality carbon steel 16Mn, 5MnV low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn240MnB other alloy steel hot-rolled or cold-formed 1020 and other low-carbon steel seamless pipe is mainly used for fluid pipes. seamless 4540Cr like carbon steel used to manufacture mechanical parts, such as cars, tractors and the force components. General seamless steel pipes to ensure The strength and flattening test Hot-rolled steel hot-rolled state or heat treatment delivery; cold to heat treatment delivery.
