Stainless steel welded pipes used in mechanical structures usually refer to special stainless steel pipes for mechanical structures manufactured by arc welding or other automatic welding methods. Usage: Mechanical parts and structural parts for automobiles, motorcycles, bicycles, machinery, furniture, decoration, etc..
According to the main use in industry, stainless steel structure tube is divided into two categories: stainless acid-resistant steel structure tubes and heat-resistant steel.
A Stainless acid-resistant steel structure tube is divided into stainless steel and acid-resistant steel. The steel that can resist corrosion in the air is called stainless steel structure tube; Steel that can resist corrosion in a variety of corrosive media is called acid-resistant steel. Stainless steel is not necessarily acid-resistant, but acid-resistant steel has good rust performance.
In addition to the five elements (C, Si, Mn, P, S), this kind of structural tube mainly contains chromium and nickel alloy elements. Such as chromium steel (Cr13 type), chromium-nickel steel (18-8 type); And on the basis of chromium-nickel steel containing molybdenum, niobium, titanium, nitrogen, and other elements in one or more.
The round, plate, belt, wire, and tube made by this kind of structural tube are widely used in chemical equipment, medical equipment, food industry equipment, family cabinets, and decoration of hotels and restaurants.
B, Heat-resistant steel is divided into heat-resistant and non-peeling steel two kinds. At high temperatures resistance to medium erosion without peeling steel is called peeling steel; A structural tube that is resistant to medium erosion at high temperature and has sufficient strength without peeling is called a heat-resistant steel structure tube.
In addition to chromium and nickel in stainless acid-resistant steel, such structural tubes also contain one or more alloying elements such as aluminum (Al), tungsten (W), cobalt (Co), and vanadium (V). Its circles, plates, belts, and tubes are widely used in petrochemical equipment, power station boilers, gas turbines, and industrial heating furnace components, as well as components working at high temperatures.
