DIN 17465 Grade GX40NiCrSi38-18 cast condition
DIN 17465 Grade GX40NiCrSi38-18 cast condition introduction
G-X 40 NiCrSi 38 18, for highest mechanical loaded parts, like grates (abrupt variation in temperature). The high nickel content is in this case the important fact for heat resistant and reduction the crack initiation danger in case of heat changing loadings
resistance:
- in oxidising burning atmosphere: 1100°C
- in reductive burning atmosphere: 1070°C
- in oxidising sulfureous gas: 1070°C
- in reductive sulfureous gas: 1000°C
