X2CrTi12 Soft-Annealed Ferritic Steel – DIN 17456 Grade for High-Temperature Applications
The material X2CrTi12 is a ferritic steel with high scaling resistance (in air up to 800 deg.) which has a certain corrosive resistance. The material does not show resistance to intercrystalline corrosion both in delivery and welded condition. Application primarily in automotive industry for silencers and for components of waste gas detoxification. The brand may be used as heat resistant steel acc. to DIN EN 10095.
