The high temperature resistance of stainless steel nuts depends on the type of stainless steel material used. Different stainless steel materials have different high temperature resistance. The following are several common high temperature resistant stainless steel nuts and their performance characteristics:
High temperature resistant 25-20 stainless steel nuts
High temperature resistance: High temperature resistant 25-20 stainless steel nuts have good overall corrosion resistance and high temperature mechanical properties, and can be used at high temperatures of 1000°C.
Other properties: This type of nut also has good low temperature performance and can still maintain considerable strength at lower temperatures. However, its disadvantage is that the yield strength of the material is low and its mechanical properties cannot be improved by heat treatment.
Precipitation hardened stainless steel 17-7PH nuts
High temperature resistance: Precipitation hardened stainless steel 17-7PH nuts have good high temperature resistance and corrosion resistance. It can be used in a variety of conditions, including RH950 and TH1050, which means that it can still maintain good performance at temperatures up to 1050°C.
Other properties: 17-7PH stainless steel is characterized by high strength and hardness, excellent fatigue performance, small heat treatment deformation, good annealing formability and good corrosion resistance. It can be hardened to high strength levels by simple heat treatment.
Conclusion
The selection of high temperature resistant stainless steel nuts depends on the specific application environment and temperature requirements. High temperature resistant 25-20 stainless steel nuts are suitable for use at temperatures around 1000°C, while precipitation hardened stainless steel 17-7PH nuts can maintain good performance at higher temperatures (such as 1050°C). When choosing, other factors need to be considered, such as material cost, processing performance, etc.
