GX5CrNiNb19-11: Heat-Treated, Quenched Grade for High-Performance Cast Parts & Industrial Applications
Material GX5CrNiNb19-11 is equivalent to trademark G-X 5 CrNiNb 18 9 acc. to DIN17445-84. The material is used for cast parts, pressure vessels as well as in food, film, photo, color, soap, paper, textile and nitric acid industry, in explosive and viscose industry. GX5CrNiNb19-11 is ic-resistant and weldable without preheating and heat after treatment. A special stabilization annealing in a range from 600 to 650 °C is accordable in order to improve the corrosion resistance.
