1) Remark: The for pressure vessels approved steel X6CrNiNb18-10, mat. no. 1.4550, is similar corrosion resistant like the X6CrNiTi18-10 (1.4541). It is resistant to intercrystalline corrosion in the delivery and also in the welded condition. According DIN 17440 : 1996-09 it is used for flat products and rods and drawn wire and acc. DIN 17441 : 1997-02 for cold rolled strips and slit strips for pressure vessels. The limiting application temperature (operating time 100000 h, no intercrystalline corrosion) amounts to 400 degrees C. For the application acc. DIN 17440 : 1985-07 (X 6 CrNiNb 18 10) resp. acc. DIN EN 10088-1,-2,-3 : 1995-08 (X6CrNiNb18-10) applies: application for the chemical apparatus construction in the cellulose industry, textile industry, rubber industry and colour industry. The steel is not high polishable because of the Nb-content and it subject to heat cracks.
