Will hot dip galvanizing affect the properties of the steel
depends on what your are dipping...i.e what its composition and properties were, was it a spring steel prior?
galvanize a Steel will lose some Small strength bu it will prolong the steel
Steel is heat treated for some applications such as bearings, drill bits and cutting tools. Hot galvanizing occurs at 860F (when zinc is molten). Tool steels are likely to lose temper and hardness at this temperature. Common steels wouldn't be affected.
