Stainless steel description
Stainless steel is an alloy of iron that contains chromium and other alloying metals like nickel, molybdenum, titanium, copper,carbon, and nitrogen. Stainless Steel Tubing is used in aircraft hydraulic lifts, factories, mills, production lines, fuel and heat industries, military, nuclear development, etc. The stainless steel pipes & tubes available in various grades such as 304, 316L, 309S, 310S, 317L, 321, 321H, 347H, 316Ti are used for manufacturing.
Stainless Steel Seamless Pipes & Tubes are formed by using Water Hydraulic Hot Extrusion Press that uses hot extruded hollows or pipes as raw material. They are used in various fields like heat exchangers, Nuclear Power Plants, Oil & Gas, Petrochemical & Refinery, Chemical & Fertilizer, etc.
Stainless steel seamless pipe is a kind of hollow long steel profile, mainly used in petroleum, chemical, medical, food, construction,mechanical instrumentation and other industrial transmission pipes and mechanical structural components. For seamless, outside diameters are from 6mm to 1400mm with wall thickness from 0.5mm to 70mm. The annual output capacity is 35,000 tons.
