Abstract Scope |
Cast chromia-forming austenitic stainless steels such as HP-type alloys are used in a wide range of industrial applications such as high temperature furnace components, radiant burner tubes, and ethylene cracking furnaces that demand high temperature microstructural stability, corrosion resistance, and creep strength. Although alumina scales offer better corrosion protection at these temperatures, developing cast austenitic alloys that form a stable alumina scale and achieve creep strength comparable to existing cast chromia-forming alloys, has been challenging. This presentation will outline the methodologies used in the development of cast Fe-Ni-Cr-Al austenitic stainless steels and highlight their high temperature environmental resistance which makes them the desired alternative to chromia-forming austenitic stainless steels for many industrial applications. This talk will also provide examples of component fabrication and their successful implementation in industrial applications.
