Stainless Steel 316Ti Flanges Manufacturer in India
SS 316ti stainless steel is a titanium-stabilized austenitic stainless steel grade that has been designed to increase its performance in a high temperature and corrosion environment. Titanium increases intergranular corrosivity resistance, eliminates carbide formation at high temperatures, and molybdenum increases pitting, crevice corrosivity, and chemical attack resistance. SS 316Ti Flanges are also commonplace in piping systems that require high thermal stability, corrosion resistance, mechanical strength and long life. The flanges are effective in high-temperature/high-pressure and chemically aggressive environments, and are provided with substantial structural integrity and leak free connection with high consistency in applications such as chemical processing, petrochemical plants, refineries, power generation, offshore installations pharmaceutical plants and other taxing industrial applications.

What Are SS 316Ti Flanges?
The SS 316Ti flanges can be manufactured in compliance with the standards of ASTM A182 F316Ti and are created out of forged and rolled stainless steel to be used as high-performance piping systems. Titanium is a stabilizing element in this grade with molybdenum which offers more resistance against corrosion, oxidation and chemical assault in harsh industrial settings. Titanium stabilization helps to avoid the formation of carbide during service and welding at high temperatures, and therefore SS 316Ti flanges are very suitable in long-term high temperature services. These flanges are made specifically for systems that are exposed to high temperature, pressure, and harsh industrial media. Chemical plants, refineries, petrochemical and heat exchangers, power plants, exhaust systems, offshore platforms, and other segments that require high thermal stability, corrosion resistance, and long-time durability are typical applications of SS 316Ti flanges.
