Aluminum tuning forks vary quite a bit by temperature, but steel forks are quite accurate, certainly well within the tolerances of other musical instruments. One should only use steel forks for anything which requires any degree of accuracy. If you do, it will probably be within the tolerances of even a piano as long as you are within a range of 60-80° F.

[/b] The change in steel forks is close to one cent for every 7° F temperature change. (Temperature goes up, pitch goes down.) So a temperature range of 20° produces about 3 cents change in the fork. If you consider 3 cents to be small, then OK. But if you consider 3 cents to be a significant error, then you better keep closer control over the temperature of that fork.
