EN 10250-4 Grade X6CrNiNb18-10 solution annealed (+AT)
EN 10250-4 Grade X6CrNiNb18-10 solution annealed (+AT) introduction
The make X6CrNiNb18-10 is comparable to X 6 CrNiNb 18 10 acc. to DIN 17440: 1985-07. Its corrosion properties are similar to 1.4541. The steel is resistant to intercrystalline corrosion also in sensitized condition. It shows a hot shortness tendency on certain welding conditions. Applicable in high amount for welded parts in chemical apparatus engineering, in food and luxury food industry, in film and photo industry as well as for household objects. The steel is unusable for mirror finishing due to the NB-content.
