EN 1.4571/ AISI 316 Ti (UNS S31635) is a titanium stabilized austenitic chromium-nickel-molybdenum stainless steel. The material is used as an alternative for 1.4404 / AISI 316L when hardness and strength at high temperature are required. Intergranular corrosion resistance of 1.4571 is improved with the addition of titanium, which prevents precipitation of chromium carbides in the grain boundaries. The 1.4571 is known for its good resistance to corrosion in most natural water (urban and industrial), provided that the concentration chloride and hydrochloric acid are not too high.
Material may also be supplied against Customer specifications, subject to enquiry.
Chemical Composition, %
The 316 Ti exhibits good corrosion resistant in low to medium concentration of chlorides, salts and hydrochloric acid as well as in organic acids. AISI 316 TI is more suitable for used in lower temperatures. Machinability of the grade is moderate, but very weldable by most standard processes and post weld heat treatment is not necessary.
Machinability: 4 (1 = poor – 10 = good)
Polishability: not possible
Corrosion class: 4 (0 = poor – 5 = good)
We supply a range of flat bars and round bars, on both stock and indent basis.
