You have to know the difference between 7.3 forged rods vs powdered metal care
Forged rods are made by heating and hammering a rod of steel, usually identified by its chemical composition, into a shape that can be used as a rod or a bar. The process is done in a high-temperature furnace with the use of hammers. The resulting forged rods are then heat-treated and tempered to improve their strength and durability
Powdered metal care is an alloy made from powdered metals including iron, copper, zinc and tin that has been mixed together with cement at high temperatures and pressure. Powdered metal is used in the production of iron alloys such as those used in shipbuilding, rails and structural components.
