[1] Preheat: Production welding by the foundry; ferritic/martensitic guidance is informative.; Preheat temperature depends on casting geometry, thickness and climatic conditions.
[2] Interpass Temperature: Production welding by the foundry; ferritic/martensitic guidance is informative.
[3] Post-weld Heat Treatment: Production welding by the foundry; ferritic/martensitic guidance is informative.; In general, production welds are major when prepared cavity depth exceeds 40% of the wall thickness; minor weld corrosion conditions may require special agreement.
Applications
For low-alloy steel EN 10213 G9Ni10, typical cast components in this material family include valve bodies, pump casings and fittings. Applications include industrial process plants, heating circuits and power-generation equipment. Service medium, temperature, material condition and the finished equipment design determine the permitted duty; the grade name alone is not an operating rating.
