Cooling And Heating Metals

In our last blog post we covered the three stages of heat treatment that include heating the metal to a set temperature the heating stage keeping it at that temperature for a specific length of time the soaking stage and cooling it down to room temperature with a method that depends on the type of metal and the desired properties the cooling stage.

Cooling and heating metals.

The hardening process increases the hardness and strength of metal but also increases its brittleness. We can use the same idea to heat up steel in an electric arc furnace. An electric arc furnace. Annealing is frequently used to soften metals including iron steel copper brass and silver.

When we pass an electric current through a piece of wire it gets hot. In both pure metals and many alloys that cannot be heat treated annealing is used to remove the hardness caused by cold working. A ferrous metal is normally hardened by heating the metal to the required temperature and then cooling it rapidly by plunging the hot metal into a quenching medium such as oil water or brine. The temperatures metals are heated to and the rate of cooling after heat treatment can significantly change metal s properties.

My clients have also been pleased with the. Most steels must be cooled rapidly to harden them. The photograph shows how hot it gets. Annealing alters the physical and chemical properties of the metal to increase ductility and reduce hardness.

3 reviews of browne heating metal works i ve used dave browne heating a few times over the years now and been more than impressed with their service fairness speed of execution and pricing. The process involves heating the metal to a specific temperature then allowing it to cool slowly at a controlled rate. This can affect dimensions and material structure.
