DIN 17440 Grade X2CrNiN18-10 solution heat-treated and quenched
DIN 17440 Grade X2CrNiN18-10 solution heat-treated and quenched introduction
Properties
- austenitic CrNi-steel
- because of addition of nitrogen gets higher yield strength, which is resistant to higher temperature, used in pressure tank construction and light constructions
- N-content lets increase the corrosion resistance
- good able for cold forming
- high polishable
Application:
- low temperature toughness up to -270°C, because of this applicable in refrigeration engineering
- suitable for chemical constructions, because of its resistance to nitric acid and other oxidising media
- for pressure tank construction up to 300°C, above 300°C subjects to authorisation
