Stress in iron (and generally in metals and alloys) facilitates and accelerates rusting.
See the links below.
it rusts
iron bending different from iron rusting
Oxidation (rusting) of iron metal is the reaction of iron and oxygen
No, iron rusting is oxidation process
Its the moisture which causes rusting of iron
How is iron gate is prevented from rusting
Rusting of iron is an oxidation reaction in the presence of water.
rusting of iron
Paint or enamel can protect iron from rusting.
rusting of iron is faster in rainy days because water is responsible for the rusting of iron i.e the presence of oxygen
Quantity of water in the air (or other medium surrounding the iron). Quantity of oxygen in the air (or other medium surrounding the iron). Additives to the iron during production. Surface area of the iron exposed. Chemicals in the air or other medium surrounding the iron that could catalyse the rusting process.
Rusting of iron is caused by water in the presence of oxygen.
