Product Introduction
TP316Ti (UNS S31635, EN 1.4571) is a titanium-stabilized austenitic stainless steel renowned for its enhanced corrosion resistance and high-temperature performance. As a variant of the 316 stainless steel family, TP316Ti incorporates titanium (Ti: 5×(C%+N)-0.7), which stabilizes the alloy against carbide precipitation during welding and high-temperature service. This makes it particularly suitable for applications where weldability and long-term corrosion resistance are critical.

TP316Ti /1.4571/UNSS31635, is a titanium-stabilized, molybdenum-alloyed austenitic chromium-nickel steel with improved machinability has similar characteristics to AISI 316L, but the TP 316Ti has better mechanical properties and strength at high temperatures. TP 316Ti (1.4571, UNS S31635) due to the addition of titanium shows higher corrosion resistance.
TP 316Ti (1.4571, UNS S31635) is generally considered but is not resistant to hot sea water. Hot chloride environments may cause pitting and crevice corrosion. TP 316Ti (1.4571, UNS S31635) HEAT RESISTANCE 316 exhibits good resistance to oxidation in continuous service to a temperature of 870 ° C and a temperature of 925 ° C. However, if corrosion resistance to water is required, continuous use at 425-860 ° C is not recommended. In this case, 316L is recommended due to resistance to carbide precipitation. When high temperatures are required at temperatures above 500 ° C, class 316H is recommended.
