Want spring to work at high temperatures, need it has a very good relaxation resistance strength, thermal stability and oxidation resistance ability, also has certain corrosion resistance ability.
If spring working temperature is high, the production of spring materials with the decrease of elastic modulus and the smaller it will lead to the bearing capacity of the spring stiffness and decline. So, want to make it can work at high temperatures we need to know the rate of change of it, you also need to calculate the decline of carrying capacity of spring using the performance impact. In accordance with the relevant provisions, general spring if work when the temperature is higher than 60 degrees, the need for its shear modulus have certain adjustment.
Used to make the spring spring steel, when the choice according to the stress of spring ? size and its properties
