1.  Heat-resistant washers are those with high creep and fracture resistance at high temperatures. They are used to protect the surface of parts of internal combustion engines, steam and gas turbines, boilers, jet engines, nuclear power plants from damage by a nut during tightening.

The high heat resistance of washers is determined by two main physical factors - the strength of the interatomic bonds of the steel from which the washer is made and its structure. Usually, the structure necessary for high strength is obtained by introducing alloying elements capable of additional hardening of the main component of steel.

2.  Stainless washers are resistant to corrosion in atmospheric conditions and aggressive environments.
