Quench C hardening is a mechanical process in which steel and cast iron alloys are strengthened and hardened. These metals consist of ferrous metals and alloys. This is done by heating the material to a certain temperature, depending on the material.uench metals is a progression; the first step is heating, i.e. heating it to the required temperature. Second step is soaking. Soaking can be done by air (air furnace), or a bath or in a vacuum. The soaking time in air furnaces should be 1 to 2 minutes for each millimeter of cross-section.
well one of the physical properties of metals is being ductile and zinc is a metal so the answer is yes= not really Zinc is hard and brittle which makes it hard to stretch it. â¦ Tungsten is a metal and is to hard to even try to turn into a wire.6 people found this useful.ell one of the physical properties of metals is being ductile and zinc is a metal so the answer is yes= not really Zinc is hard and brittle which makes it hard to stretch it. â¦ Tungsten is a metal and is to hard to even try to turn into a wire. 6 people found this useful.
