316 And 316L Stainless Steel Grades

316 and 316L stainless steel grades

In order to promote stainless steel pipes, China has started from the 1990s to reduce the wall thickness and reduce the cost, to solve the technical problems of "high diameter wall ratio and high precision" thin-wall stainless steel pipes, so that stainless steel pipes have been promoted and applied, and have developed rapidly. A pipeline can be fully promoted and applied, without localization. At present, some domestic manufacturers have the ability to produce and further develop thin-wall stainless steel pipes and fittings.
