Austenitic steels

TP 316LMo • UNS S31603 • 1.4435 • TPS-INOX 4435-316LMo

Datasheet

Due to the lower carbon content, intercrystalline corrosion resistance is also guaranteed after welding. The increased molybdenum content improves the general corrosion resistance, particularly to reduced acids and chloride-containing fluids. Weldability according all processes (except for autogenous welding) without subsequent heat treatment. TPS-INOS 4435-316LMO is used in the pharmaceutical industry, the synthetic fiber manufacturing industry, the pulp and cellulose industry and for chemical fertilizer production plants. This steel is polishable. TPS-INOS 4435 complies with the requirements of Basler standard 2. In case of continuous operation up to 400°C it is resistant to intercrystalline corrosion. The machinability of this grade is reduced.
