Stress relieve

I have made a batch of torsion springs for my steamer and according to my spring making literature have now to stress relieve them at 260C for 1 hour.

Apart from putting them in a domestic oven are there any solutions etc. that they could be put in to maintain an accurate temperature at home?

Hi Paul,

See the thread on salt baths, or if you want a safer life a deep fat fryer on 'high' should do the job.

Be warned though, for some reason my little bits of steel are seen as harmful to human health even if they are lying on top of or inside steel cockware...

Is that your latest project Neil?

I was inspired by one of Blackadder's codpieces...

Here is part of the article on spring making **LINK**

When I first designed and stress relieved the springs that overcome a problem that I had with coil springs I used cooking oil but the risk from fire was great and wondered if there was a less inflammable oil for the temperatures required

Jason,Neil,

A safer medium for tempering spring steel, if you must use industrial practise, would probably be lead (as long as you take the appropriate care and precautions). You could then use the molten lead to make sea fishing weights and have a few hours fishing in the fresh air. You could argue this was therapeutic on account of breathing the poisonous lead fumes (which is not the case as long as the temperature remains below 450 deg C or there about).
