316 stainless steel pipe is a kind of hollow long circular steel, mainly widely used in petroleum, electronics, medical machinery and other industries. 316 stainless steel pipe is a kind of universal stainless steel material, rust resistance is stronger than 200 series stainless steel material. High temperature resistance is also relatively good, can reach 1000-1200 degrees.
From the perspective of metallography:
304 is susaturated solid solution structure, 310 is subcooled austenite structure. 317 is a completely quenched martensite structure; 321 is a typical tempered sorbite + ferrite biphase structure. 309 is a metastable or Bayes type.
313 is similar to 347; 324 is similar to 333; 347 is similar to 310; 332 is similar to 333.326 is a type of super Austrian duplex stainless steel. 329 is a biphasic composition of ferrite and pearlite.
Application field:
Decorative steel pipes for building decoration, steel pipes for vehicle manufacturing, scaffolding and other industrial distribution pipes, precision steel pipes for agricultural engineering equipment, steel pipes for chemical distribution pipes, thick wall seamless steel pipes for thermal equipment, various boiler tubes for other industries, special tubes for special purposes, high-quality thin and thick wall seamless steel pipes
