EN 10088-1 Grade X2CrNiMoN17-11-2 Solution-Annealed Steel – High Strength & Corrosion Resistance

Material X2CrNiMoN17-11-2 is comparable to trademark X 2 CrNiMoN 17 12 2 acc. to DIN 17440 : 1985-07. This material is a fully austenitic steel which shows higher strength and structure stability owing to nitrogen addition. It has high resistance in oxidizing media. Increased pitting index owing to nitrogen. Application in chemical apparatus engineering for pressure tanks, in cellulose, color, oil, soap and textile industry, in breweries and dairies. The steel is suitable for mirror finishing and resistant to selective corrosion especially in welded condition. The material shows resistance to intercrystalline corrosion also in sensitized condition.
