Finally emphasis on the importance of surface treatment in the production, strictly control the process parameters when anti rust.

For the ferritic stainless steels, grain growth in the heat affected zone, welding joint ductility and toughness sharp decline, brittle, easy to form cold cracks in the welding residual stress.

Stainless steel, with its excellent corrosion resistance, abrasion resistance, heat resistance, and its shiny, luxurious surface, and are widely used in various fields of the national economy.

We know that the stainless steel seamless pipe has a quality demanding for seamless pipe in the environment of high temperature and pressure.
