DURMAT
AS-768 |
Cr 44 / Ti 1/ Ni balance |
Hardness: 32 HRC |
Good resistance against corrosion and oxidation, e.g. in vanadium or sulphur vapor up to 980°C. Good bonding. Coating of boiler tubes, finned tubes, super heat tubes. |

DURMAT
AS-810 |
Al 6 / Si 0.45 / Cr 26 / Fe balance
|
Hardness: 200-220 HV
|
Coating of heating elements and strip conductors on ceramics, can be sprayed relatively cold, therefore heat adding can be reduced during the spraying process. Resistant against Gas corrosion, oxidation stability up to 870 °C also under atmospheres with Vanadium and sulphur impurity. High conducting capacity, rapid machining, good adhesive characteristics. |
