Overview:

Krystal is a renowned exporter, manufacturer, stockist, supplier, and stockholder of high-quality Stainless Steel Alloy Seamless Tubes. These tubes are celebrated for their excellent corrosion resistance, durability, and high strength, making them ideal for a wide range of applications including petrochemical, pharmaceutical, food processing, and marine industries. Stainless steel alloy tubes maintain their integrity and performance across various temperature ranges and environments, offering superior weldability and ease of fabrication. This ensures reliable and long-lasting performance in even the most challenging conditions.

316Ti (UNS S31635) is a titanium stabilised version of 316 molybdenum-bearing austenitic stainless steel. The 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as 304. They also offer higher creep, stress-rupture and tensile strength at elevated temperature. High carbon Alloy 316 stainless steel can be susceptible to sensitisation, the formation of grain boundary chromium carbides at temperatures between approximately 900 and 1500°F (425 to 815°C) which can result in intergranular corrosion.

Resistance to sensitisation is achieved in Alloy 316Ti with titanium additions to stabilise the structure against chromium carbide precipitation, which is the source of sensitisation. This stabilisation is achieved by an intermediate temperature heat treatment, during which the titanium reacts with carbon to form titanium carbides. This significantly reduces susceptibility to sensitisation in service by limiting the formation of chromium carbides. Thus, the alloy can be used for extended periods at elevated temperatures without compromising its corrosion resistance. 316Ti has equvilent corrosion resistance to sensitisation as the low carbon version 316L.
