Alloy Steel Pipe/Tube
Alloy steel pipes are divided into structural seamless pipes and high-pressure heat-resistant alloy pipes. Mainly different from the production standard of alloy pipe and its industry, the annealing and tempering of alloy pipe changes its mechanical properties. meet the required processing conditions.
Its performance is higher than that of ordinary seamless steel pipes. The chemical composition of alloy pipes contains more Cr, and it has high temperature resistance, low temperature resistance and corrosion resistance.
Alloy steel pipes are widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries.
Alloy steel metal is a versatile material that is well-suited to in major industry. Alloy steel is a particularly hard material that withstands heat and resists abrasion, and is available in a number of grades that are each suited to specific applications.
