1.4571 (DIN EN 10216-5 : 2004-11) X6CrNiMoTi17-12-2 1.4571 DIN EN 10216-5 : 2004-11 DIN EN 10216-5 : 2004-11 replaced by DIN EN 10216-5 : 2014-03 Replaced Germany X6CrNiMoTi 17-12-2 X6CrNiMoTi17-12-2 1.1.2 1)
1) Remark: The grade X6CrNiMoTi17-12-2 is comparable to X 6 CrNiMoTi 17 12 2 nach DIN 17440 : 1985-07. The material is a variant of 1.4401, stabilized by Ti. Increased corrosion resistance owing to the high Mo-content, especially to non oxidizing acids and halogenated media. Application in chemical apparatus engineering preferentially for textile, sulfite, cellulose, fatty acid, rubber and color industry. The steel has an increased resistance to intercrystalline corrosion also in sensitized condition. This material is unsuitable for mirror finishing. Application temperature: -200 to 550 deg. (for comparable DIN-make). X6CrNiMoTi17-12-2 is used in construction trade due to its very high corrosion resistance and strength for masonry anchorage in concrete, as concrete steel for chimneys, facades and sanitary engineering. The Mo-alloyed stainless steel is permitted for load bearing components.
