stay that shape& not bend back when a load is applied?

Would I heat it to 'red', bend it, then quench it in water/oil? Or bend
it
cold, heat it, quench it?

Thinking about this, heating and quenching would do nothing to mild steel,
as it doesn't have enough carbon content. Case hardening would make it
brittle.

Case hardening should not make it brittle.
Its a composite.. mild steel core, high carbon skin.. it shouldn't be
brittle.
