DIN 17465 Grade GX40CrNiSi27-4 cast condition

DIN 17465 Grade GX40CrNiSi27-4 cast condition introduction

G-X 40 CrNiSi 27 4, normally for heat resitant cast pieces, for example moveable oven and burning parts, gates, tracks, rolls, burning jets, shapes for glass. Especially for parts of oven, when high demand still against sulfureous gases to be steady are, like attachments for super heater, gripper arbor, annealing retorts and similar parts.
resistance:
- in oxidising burning atmosphere: 1100°C
- in reductive burning atmosphere: 1100°C
- in oxidising sulfureous gas: 1100°C
- in reductive sulfureous gas: 1080°C
