316L elbow is a stainless steel material grades, AISI 316L is the corresponding US label, sus 316L is the corresponding Japanese label. China's unified digital code S31603, the standard grade 022Cr17Ni12Mo2 (new standard), the old brand is 00Cr17Ni14Mo2, that contains mainly Cr, Ni, Mo, the number that probably contains the percentage. 316L because of its excellent corrosion resistance in the chemical industry has a wide range of applications, 316L elbow is a type of 18-8 austenitic stainless steel derivatives, add 2 to 3% Mo element. On the basis of the 316L, also derived a lot of steel, such as adding a small amount of Ti derived 316Ti, add a small amount of N derived from 316N, increase the Ni, Mo content derived 317L.

High-quality products



 



 



 


Stainless steel stamping elbow electrode has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, petroleum, medical machinery manufacturing.tainless steel elbow are mainly used for connecting two pipes.  all the fittings in the piping system use , 80% proportion  is elbow. Typically,we  choose different elbow forming process according to different wall thickness and different materials. Currently, manufacturers of seamless elbow forming process commonly use hot push, stamping, extrusion.
