What are the super precision stainless steel tube processing techniques?

What are the super precision stainless steel tube processing techniques? Foshan Gang is stainless steel mainly explains two processing technology:

1. The annealing

Annealing refers to the heat treatment process of slowly heating ultra-precision stainless steel tubes to a certain temperature, keeping them for enough time, and then slowly cooling them (generally with furnace cooling). Its purpose is to reduce hardness and improve machinability; Eliminate residual stress, stabilize size, reduce deformation and crack tendency; It is a metal heat treatment process to refine grain, adjust microstructure and eliminate microstructure defects.

2, online bright solution

On-line bright solid solution refers to the heat treatment process in which the stainless steel is heated to 1100℃ and the solid solution is maintained at a constant temperature, so that the carbides are completely or basically dissolved, and then cooled to room temperature quickly to obtain the carbon supersaturated solid solution. This process improves toughness and corrosion resistance and eliminates stress and softening for further machining or molding.

Solid solution is generally used in the pipe has mechanical properties requirements of the product, that is to say, online solution is a process of making stainless steel pipe, in order to face foshan Gang is ultra precision stainless steel tube bending molding, expanding, shrinking and other processes.
