Ferritic Heat Resistant 1.4713 1.4724 1.4742 Stainless Steel Sheet and Coil

Characteristic properties

• Excellent resistance to oxidising and reducing sulphur
• containing atmospheres
• Good resistance to oxidation
• High thermal conductivity – low thermal expansion

Applications
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:
• Chemical industry (drums)
• Power industry (coal burners)
• Metalworking industry (heat treatment boxes)
• Furnace technology (walls, doors)

1.4713 stainless does not form brittle phases but should only be exposed to moderately corrosive atmospheres

owing to its low chromium content.

1.4724 stainless is a truly stainless high temperature grade with 13% chromium.

It is not critical in terms of embrittlement. 

1.4742 stainless 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 stainless 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.
