What effect does bending, stress, or machining have on the tendency of iron to corrode?

asked by lauren
  1. It depends on the type of iron: But basically, bending, stress cause microcracks allowing moisture and oxygen into the metal.

  3. Nails are mainly steel, a mixture of iron and other metals. Stress causes microcracks and fatigue cracks.
