316Ti Stainless Steel  Description

Type 316Ti(UNS 31635) is a  Titanium stabilized austenitic chromium-nickel stainless steel containing  molybdenum.

This addition increases corrosion resistance, improves resistance  to pitting chloride ion solutions and provide

increased strength at elevated  temperatures. Properties are similar to those of type 316 except that 316Ti due  to

its Titanium addition can be used at elevated sensitisation temperatures.  Corrosion resistance is improved,

particularly against sulfuric, hydrochloric,  acetic, formic and tartaric acids, acid sulfates and alkaline chlorides.
