High temperature ferritic stainless steel
Stainless ferritic high temperature steels are mostly used in high temperature applications with sulphurous
atmospheres and/or low tensile loads such as for installations within:
|EN/DIN||AISI||Max. service temperature|
1.4713 does not form brittle phases but should only be exposed to moderately corrosive atmospheres owing to its
low chromium content.
1.4724 is a truly stainless high temperature grade with 13% chromium. It is not critical in terms of embrittlement.
1.4742 shows better scaling resistance than 4724 and can be subjected to reducing sulphur environments without risk.
It is subject to 475°C embrittlement and grain coarsening at temperatures above 950°C. σ-phase may form after long
time exposures to temperatures around 650°C.
1.4762 - with the highest chromium content- is the most resistant to reducing sulphurous gases. It is susceptible to
the same embrittlement phenomena as 4742 whilst σ-phase forms during long exposures in the range 600°C to 800°C.
