How are steel spring Springs hardened after forming?
After forming, these springs are hardened by quenching in oil and tempered. Steel wire springs are in pre-tempered state, especially for valve springs of 10 mm diameter. Steel has the highest endurance limit of all spring materials. Cold working particularly, cold drawing improves it further.
What’s the best way to bend spring steel?
When part reaches proper color slide off plate into oil ( I use ATF) Polish so you can see color of clean steel, place on plate again, heat until part turns blue to straw color and quench again in oil. Color (heat) will need to be tinkered with but this will give you a basic idea how it’s done.
What should the temperature be for annealing spring steel?
This steel retains high percentage of the room temperature properties at 150°C and higher. Forging is done from 1050°C to finish at 850°C. The hot forming to springs is done at 920-830°C. Annealing is done 640-680°C.
