Material Notes:

Description: This andalusite based brick is characterized by a low porosity and a good creep resistance (After 24 hours at 1350Â°C under a load of 0.2 MPa gives between 14th and 24th hour a creep of 0.006% per hour.) Application: anode baking furnaces, blast furnace stoves.Remarks: This data represents average values, obtained from samples that were cut from standard bricks.Information provided by Gouda Vuurvast.
