Property Features

Heat resisting austenitic steel. Superior high temperature strength and excellent
toughness. Heat resistance in air up to 1150°C. Good resistance in oxydizing, nitrogenous and low oxygen gases. Medium resistance in sulphurous, oxidizing gases but sensitive to the action of reducing sulphurous gases. Embrittlement only occours after prolonged exposure in the temperature range of 650 to 900°C. Therefore in the case continous working temperatures more than 950°C are recommended.
