Commonly known as air, steam and water and other weak corrosive medium corrosion of steel for stainless steel, said acid, alkali, salt and other corrosive medium of chemical corrosive steel for acid resistant steel. Stainless steel and acid resistant stainless steel is the general name of stainless steel, referred to as stainless steel. Chromium is the main alloying element, in addition to the nickel, stainless steel pipe fittings, such as molybdenum, titanium, niobium, molybdenum, etc..
Stainless steel tube material mainly has austenitic stainless steel, ferritic stainless steel, martensite stainless steel, duplex stainless steel and precipitation hardening stainless steel. Stainless steel tube is widely used in petroleum, chemical, papermaking, chemical, automobile, aircraft, power plant, decoration and other fields.
Production method of stainless steel seamless pipe can be hot, hot extrusion, cold rolling and cold drawing. In recent years due to the progress of the technology of continuous casting and continuous rolling and welding technology and application to nondestructive detection technology, continue to raise the quality of stainless steel welded pipe can be in the field of use partial substitution of stainless steel seamless pipe, and the price than seamless pipe about 20%. Current industrial application of stainless steel pipe and stainless steel seamless pipe, respectively, 50%.
