Glossary of Stainless Steel Terms - Unified Alloys
Phase in certain steels, characterized as a solid solution, usually of carbon or iron carbide, in the hamma form of iron. Such steels are known as austenitic. Austenite is stable only above 1333 (degrees) F. in a plain carbon steel, but the presence of certain alloying elements, such as nickel and manganese, stabilizes the austenitec form, even at normal temperatures.

Silicon and phosphorus react vigorously with iron upon heating, forming silicides (for example, Fe 3 Si) and phosphides (Fe 3 P). The compounds of iron with many elements (such as oxygen and sulfur) have a crystalline structure and variable composition; thus, in the monosulfide the sulfur content can vary from 50 to 53.3 atomic percent.
