EN 10088-1 Grade X2CrTiNb18 soft annealed (+A)
EN 10088-1 Grade X2CrTiNb18 soft annealed (+A) introduction
Material X2CrTiNb18 is comparable to X 6 CrTiNb 18 (here higher C-content). It shows resistance to intercrystalline corrosion both in delivery and welded condition. This material is a structure stabilized stainless steel. Application for welded parts in dairy and food industry as well as in breweries. The material may be used as a heat resistant steel acc. to DIN EN 10095 : 1999-05.
