    Abstract

    Material flammability is thought to increase with increasing oxygen concentration, increasing pressure, and increasing temperature. Interest in the effects of increasing pressure and increasing sample temperature on the flammability of metals led to an industry-sponsored program for heated promoted combustion testing of metals. In this paper, the results of heated promoted combustion tests from the industry-sponsored 98-1 program are reported. Thirteen materials were tested as heated 3.2-mm (1/8-in.) diameter rods in an enriched oxygen, elevated pressure environment. Tests were performed in 100 % oxygen, and the temperature of the sample rods varied between 260 and 1093°C with test pressures ranging from 0.2 to 2.8 MPa. The test materials were 316 stainless steel, Incoloy® 800 HT, Hastelloy® C-276, Hastelloy C-22, Inconel® Filler Metal 601, Inconel Filler Metal 617, Haynes® 230, Haynes 214, Hastelloy X, 310 stainless steel, alonized Haynes 230, 304 stainless steel, and alonlzed Incoloy 800 HT.
