High-Temperature 321 Stainless Steel—The best stainless steel for high-temperature applications. These washers won't deform or lose strength when exposed to high heat up to 1500° F. They resist corrosion from mild cleaners, such as ammonia and acetone, but they can't withstand salt water or harsh chemicals as well as 316 stainless steel.
