Description

Trademark X6CrNiTi18-10, comparable to X 6 CrNiTi 18 10 acc. to DIN 17440-85 is the stabilized by Ti variant of 1.4301(X 5 CrNi 18 10). Therefore, the steel is after welding resistant ot intercrystalline corrosion also at material thicknesses > 6 mm. Large-scale application for welded components in chemical apparatus engineering as well as in food, luxury food, fatty and soap industry, in film and foto industry, in leather and sugar factories and for household appliances. The steel is accredited for pressure vessel construction up to 300 °C. Application up to 550 °C. is possible subject to absence of media causing intercrystalline attack. The steel is unsuitable for mirror finishing owing to the Ti-addition. X6CrNiTi18-10 is accredited in construction trade for load-bearing components (extended approval certificate No. Z-30.44.1 of the Institut für Bautechnik Berlin dated 1 February 1994). In this approval certificate are compiled demands on materials, calculation, construction and monitoring. Strength grades E 225, E 355 are common.
