Material Notes:
INCOLOY® alloy 832 is a low cost stainless steel developed specifically for domestic and industrial sheathed heater applications. With specific chemistry additions to ensure satisfactory formulation of a protective and aesthetically pleasing surface oxide film, it can replace, for example, Type 309 stainless steel, or the more expensive, higher nickel products such as INCOLOY alloys 800 or 840 (if cost is the only consideration).The alloy exhibits excellent thermal stability and good resistance to hot salt corrosion, and to pitting. It is readily formed and has excellent weldability, making it suitable for use on high output continuous strip welding machines.Information Provided by Special Metals Corporation
