Simplex Fittings is one of India’s leading manufacturers of high quality Stainless Steel 321 /321H Pipes and Tubes as per international standard quality of raw materials which find application all over different sectors.

Stainless Steel 321 Pipes Tubes is an austenitic chromium-nickel product that contains Titanium content in it, which is generally suggested for the components that are being fabricated by welding which further cannot be subsequently annealed. Also referred as UNS S32100, these SS 321 Pipes Tubes is in fact a stabilized austenitic product similar to SS 304 but in the company of a titanium addition. Well, this titanium addition in it prevents or reduces carbide precipitation during welding and in the temperature range of 427 Deg Celsius to 816 Deg Celsius service.
