316Ti Stainless Steel

316Ti stainless steel contains a small amount of titanium element based on 316 Austenitic stainless steel, titanium content is typically around 0.5%, adding the titanium can stabilise the structure of the 316 at temperatures over 800°C. it prevents carbide precipitation at the grain boundaries and protects the metal from corrosion. The main advantage of 316Ti is that it can be held at higher temperatures for a longer period without sensitisation (precipitation) occurring.

316Ti stainless steel is a derivate of 316 stainless steel, and retains physical and mechanical properties similar to standard grades of 316。

316Ti, 316, 316L And 316H

澳门凯发娱乐316 is basic grade of this group, 316L is low carbon content of 316, dual certified 316/316L is required for actual uses, 316H carbon element range from 0.04 to 0.1%, 316Ti stainless steel is grade to add titanium based on 316 stainless steel.

But 316Ti is not as common as 316 and 316L stainless steel to use, although with a higher carbon content, 316Ti have no mechanical property advantage, in many case, 31/316L dual certification is possible alternative grade of 316Ti.

316Ti stainless steel resist temperatures around 600-900°C, high temperature service (above 1000° F), but compared to 316H, there is no advantage in using 316Ti for high temperature。
