EN 10095 Grade X9CrNiSiNCe21-11-2 solution annealed (+AT)
EN 10095 Grade X9CrNiSiNCe21-11-2 solution annealed (+AT) introduction
Fully austenitic steel of high scaling temp. of 1150°C in air (highest application temp. in air), warranted scaling resistance for wide and fast thermal fluctuation, but no resistance in reducing athmosphere. Excellent creep behaviour and high deformation resistance. Application for furnace components, hood annealing and muffle furnaces, lifting bar furnaces, sealing sheets, radiator tubes, charging cages, insert boxes, recuperators as well as for combustion nozzles and for strongly loaded components of waste gas detoxification facilities.
