1.4776 (DIN EN 10295 : 2003-01) GX40CrSi28 1.4776 DIN EN 10295 : 2003-01 Supersedes DIN 17465 : 1993-08 Valid Germany GX40CrSi29 1.1.2 ≤ 1150 1)
1) Remark: According to DIN EN 10295 : 2003-01, the highest application temperature in air is 1150 °C for the material GX40CrSi28, material number 1.4776 (the former G-X 40 CrSi 29 according to DIN 17465 : 1977-09). The following is valid for the comparable DIN-material: Because of its relatively high scale-resistance, it is predominantly suitable for burner drums, burner nozzles and pots, burner crosses and annealing retorts. Furthermore for agitator arms and teeth, chutes and guard ring segments, hearth plates, case hardening boxes, glowing helixes, crucibles and transport rolls. Durability: - with an oxidizing combustion atmosphere: 1150 °C, - with a reducing combustion atmosphere: 1100 °C, - with oxidizing gases containing sulphur: 1120 °C, - with reducing gases containing sulphur: 1080 °C.
