Product Description

UNS S31635 Alloy 316Ti Stainless Seamless Steel Pipe

Product Overview

316Ti/1.4571 ASTM A312 Seamless Heat Exchanger Stainless Steel Tubes

ASME SA213 / ASTM A213 316Ti UNS S31603, EN 10216-5 1.4571 Stainless Steel. Similar to Grade 316L but with superior high-temperature strength and mechanical properties. Ideal for equipment exposed to aggressive corrosive conditions and high-temperature applications, including automotive flexible connectors, welded bellows, chimney liners, and flexible ducting.

Material Characteristics

UNS S31635 (316Ti) is a titanium-stabilized version of 316 molybdenum-bearing austenitic stainless steel. The 316 alloys offer superior resistance to general corrosion and pitting/crevice corrosion compared to conventional chromium-nickel austenitic stainless steels like 304. They also provide higher creep, stress-rupture, and tensile strength at elevated temperatures.

Titanium additions stabilize the structure against chromium carbide precipitation, which significantly reduces susceptibility to sensitization. This allows the alloy to be used for extended periods at elevated temperatures without compromising corrosion resistance. 316Ti has equivalent corrosion resistance to sensitization as the low carbon version 316L.
