304 Stainless Steel Welded Round Pipes Tube

SS 304 Tubes Stainless steel pipe is a type of hollow round steel widely used in industrial conveying pipelines and mechanical structural components such as petroleum, chemical, medical, food, light industry, and mechanical instruments. In addition, with the same bending and torsional strength, it is lightweight and therefore widely used in the manufacturing of mechanical parts and engineering structures.

Product Introduction

1. Heat treatment process
The solution treatment temperature of 304 stainless steel welded pipe is 1080-1100℃, and the cooling method is water cooling or air cooling. The annealing temperature in the middle of cold processing is mostly 850-970℃, and the water is cooled after holding for a certain time. The structure of the steel after solution treatment is austenitic structure, and sometimes there is a small amount of ferrite.
Step 2: Welding
304 stainless steel welded pipe inhibits carbide precipitation during welding, and can be welded by a general method. Manual arc welding, containing carbon 0.04%-0.06% thin section size of 304 stainless steel can be used O 002 electrode, after welding does not produce intergranular corrosion tendency, for thick section, to maintain the resistance to intergranular corrosion after welding, need to carry out post-welding heat treatment, if not heat treatment, should be changed to 304L stainless steel or stable austenitic stainless steel.
It's a combination of two things, so it's very popular.
