1.Heat-resistant nuts are those that have high creep and fracture resistance at high temperatures. They are used for fixing parts of internal combustion engines, steam and gas turbines, jet engines, boilers, nuclear power plants, etc.
The high heat resistance of the nut is determined by two main physical factors - the strength of the interatomic bonds of the steel from which the nut 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 nuts are resistant to corrosion in atmospheric conditions and aggressive environments.
* Manufacture of nuts according to other GOST standards and drawings
** The cost is calculated individually for each application
