Cleveland-Cliffs Thermak 17 is a ferritic stainless steel that is stabilized with both titanium and niobium. When given a high-temperature, final solution anneal, the alloy exhibits dramatic creep resistance. The dual stabilization prevents carbide sensitization exposure and makes the alloy thermally non-hardenable. Cleveland-Cliffs Thermak 17 is designed for demanding, hot-end automotive exhaust applications where intermediate or high chromium grades may not be sufficient or where down gauging for lightweighting is desired. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as creep. It also includes information on corrosion resistance as well as forming and joining. Filing Code: SS-1345. Producer or source: Cleveland-Cliffs Inc.
