TP 316/TP 316L | UNS S31600/31603 | TPS-INOX-4401/4404-316/316L

These grades belong to the family of 17%Cr12-13%Ni steels containing 2,0-3,0% Mo. This standard grade is used where specific attributes of other members of the family are not necessary – eg. no likelihood of intercrystalline corrosion caused by welding. Special for TP 316L, low carbon content, minimizes chromium carbide preciptation and improves resistance to intercrystalline corrosion. After TP 304/304L type steels, these TP 316/316L grades are the most widely used austenitics. Good high temperature oxidation resistance up to 900°C. In the damp industrial or onshore atmospheres of Europe, they perform better than TP 304/304L and ferritic grades. In low temperature seawater they offer limited resistance to pitting but are susceptible to crevice attack. Their short- and longtime properties at elevated temperatures are also superior to those of comparable TP 304/304L grades. Main applications: Pipe and heat exchanger tubes in chemical and petrochemical plant, in boilers and food industry.
