    • Description:
      "The Bureau of Mines is conducting research on fe-based alloys using si and al additions to reduce the cr required for heat-resisting applications. Part of this research is being done to evaluate alloys containing (8-10)-cr-(10-14)ni-(0-8.5)Si-(0-4)al to determine which of these alloys have austenitic structures, as well as fabrication properties and oxidation resistance sufficient to substitute for type 304 stainless steel. Based on initial results, an fe-10cr-11ni-5si alloy and an fe-8cr-13ni-5si alloy were selected for evaluation of oxidation, stress rupture, and tensile properties. Both alloys have oxidation resistance at 700 deg and 800 deg c that is better than that of type 304 stainless steel. The stress rupture strengths are less than that of type 304 stainless steel but significantly better than that of commericial heat-resisting steels with similar cr contents. Yield strengths of the alloys were equivalent to that of type 304. Both alloys had high tensile strengths comparable to those of stainless steels that transform to martensite during straining (e.g., type 301). These alloys have weld-hot-cracking resistance comparable to that of type 304 stainless steel. This initial study shows that si has potential as a substitute for cr in stainless steels for heat-resisting applications." - NIOSHTIC-2
