Stainless Steel Seamless Tube ASTM A213 ASME SA213 -10a 0Cr18Ni12Mo2Ti TP316Ti 57MM*3.0MM*3010MM UNS S31635 1.4571
0Cr18Ni12Mo2Ti, TP 316Ti=UNS S31635=1.4571, This is one of the family of 17%Cr12-13%Ni steels containing Mo of 2,0-2,4% stabilized with Ti which minimizes chromium carbide precipitation and improves resistance to intergranular corrosion. In the damp industrial or coastal 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 long-time properties at elevated temperatures are also superior to those of comparable TP 304/304L grades.
