DIN 17440 Grade X6CrNiTi18-10 quenched (+Q)
DIN 17440 Grade X6CrNiTi18-10 quenched (+Q) introduction
Properties:
- is the with titanium stabilised variant of 1.4301
- thus after welding also with material thicknesses > 6 mm resistant to intergranular corrosion
- due to the Ti-additive the steel is not high polishable
- is certified for the construction of pressure tanks to 300 °C, if no disintegration of grains-releasing media are present, then up to 550°C is possible
- the strength grades E 225, E 355 are usual.
Application:
- employment in large extent for welded parts in the chemical apparatus engineering
- food, luxuries, fat and soap industry
- in the film and photo industry, in leather and sugar factories and for houseware
- in architecure for construction units with supporting function is certified (extended licence notice No. Z-30.44.1 of Institut für Bautechnik Berlin from 1 February 1994)
