As with all on-hit abilities, Steel Tempest will stack Spell Weaving, but it will not benefit from the bonus spell damage. Likewise, it will not stack Blade Weaving, but it will benefit from Blade Weaving's bonus AA damage.

Any time you're confused about abilities that apply on-hit effects, just think of them as auto-attacks.
