EN 10028-7 Grade X6CrNiMoTi17-12-2 solution annealed (+AT) introduction
The austenitic steel X6CrNiMoTi17-12-2 is the sensitized by Ti variant of 1.4401. Increased corrosion resistance especially to nonoxidizing acids and halogenated media due to the high Mo-cotent. Increased resistance to intercrystalline corrosion even in sensitized condition due to the Ti-content. Material is unusable for mirror-polishing, in opposition to 1.4404.
Allowed for pressure vessel construction up to 300 °C, up to 550 °C if there are no media causing intercrystalline corrosion. The steel is applicated in civil engineering due to its high corrosion resistance and strength for masonry anchorage coupler in concrete, as reinforcing steel for chimney, facades and sanitary engineering. The Mo-alloyed steel is permitted for structural parts (extended approval certificate Nr. Z-30.44.1 of the Institut für Bautechnik Berlin, dated 01/02/1989. In this approval certificate are scheduled material, calculation, construction and monitoring demands. Strength grades E 225 and E355 are common.
Application: in chemical apparatus engineering preferable for textile-, sulfite- cellulose, fatty acid- rubber and coloring industry
Application temperatur: -200 to 550 °C
