These tubes of INCOLOY Alloy 8 0 0 have stood 56,900 hours of 1660°F. heat... without a single failure! These tubes of INCOLOY* Alloy 800 are in the Solar Nitrogen Chemical's steam methane reformer furnace at Lima, Ohio. This alloy was chosen for four very good reasons : 1. Extraordinary rupture strength and creep resistance. 2. Excellent oxidation resistance — even in the most severe combus tion gas atmosphere. 3. Freedom from "sigma" phase em-
brittlement in the critical 11001600°E range and ability to be heated indefinitely without losing its ductility or impact strength. 4. Exceptional resistance to carburization —doesn't become embrittled even after prolonged heating in various atmospheres. That's why Solar has chosen INCOLOY Alloy 800 for its hydrogen furnace tubing. (9,744 feet of it, to be exact.)
