Pipes for petroleum, chemical, medical, food, light industry, mechanical instrumentation, and other industrial pipelines and mechanical structural parts are widely used as stainless steel welds.
In addition, when the bending and torsion strength are the same, the weight is lighter, which is also widely used in manufacturing mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils.
