316L Stainless Steel Tube

Stainless Steel 316L Tube is made up of the 316 material with low carbon content. The 316 material is made up of chromium nickel alloy with the addition of molybdenum to the composition. This combination makes the material corrosion resistant to most hostile conditions. The Stainless Steel 316L tube is easy to weld upon and it is one of the most used stainless steels next to the 304 steel. The applications range from domestic to high end industrial applications. The material is especially corrosion resistant to chloride ion rich environments so that it is used mostly in the sea water desalination plants, water supply lines and in marine applications.

The SS 316L tubing produced by us is of high quality. We test the products according to international standards and supply to a very large customer base. Steel India Co. is also one of the leading manufacturers, stockiest and supplier or the ASTM A554 TP316L tube which is a variation of the 316 grade pipes. There are different nominal sizes in the ASTM A270 TP316L tube range and we produce them all. There are different manufacturing methods and types of the UNS S31603 tubing as well. You can buy the SS 316L seamless tubing or the welded tubing from us in any desired requirements.
