LSAW Steel Pipe

　　We all know that 304 stainless steel pipe for pressure pipe components, for the production of relatively high demand, the general cold forming temperatures are not up to the production requirements, so the need for 304 stainless steel pipe heat treatment process, the industry collectively referred to as solution treatment. To achieve the heat treatment process is divided into the following steps: 　　1.304 stainless steel heat treatment - annealing 　　The stainless steel tube heated to a certain temperature and heat for a period of time, and then make it slowly cooling, called annealing. Steel annealing is the steel heated to a phase change or partial phase transition temperature, after cooling slowly cooling after the heat treatment method. 　　2.304 stainless steel heat treatment - normalizing 　　Normalizing is the heating of stainless steel to a critical temperature above, so that all stainless steel into uniform austenite, and then naturally cooled in air heat treatment. It ca...
