High alloy seamless steel pipe is a kind of seamless steel pipe. Its performance is much higher than that of ordinary seamless steel pipe. Because this steel pipe contains more Cr, its high temperature resistance, low temperature resistance and corrosion resistance are other seamless steel pipes. Steel pipes are not comparable, so alloy pipes are widely used in petroleum, chemical, electric power, boilers and other industries.

High alloy seamless steel pipe contains elements such as silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earths, etc.
High alloy seamless steel pipe is a long strip of steel with a hollow section and no joints on the periphery. Steel pipes have a hollow section and are used in large quantities as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, High alloy seamless steel pipe has a lighter weight when the bending and torsional strength is the same. It is a kind of economical cross-section steel. It is widely used in the manufacture of structural parts and mechanical parts, such as petroleum transportation and stair railing. , Bicycle racks and steel scaffolding used in construction. The use of High alloy seamless steel pipe to manufacture ring-shaped parts can increase the utilization rate of materials, simplify the manufacturing process, and save materials and processing man-hours. For example, rolling bearing rings, jack sleeves, etc., have been widely manufactured with steel pipes. High alloy seamless steel pipe is also an indispensable material for all kinds of conventional weapons. Gun barrels and barrels are all made of steel pipes. In addition, when the ring section is subjected to internal or external radial pressure, the force is more uniform. Therefore, most High alloy seamless steel pipes are round pipes.
