3 Lessons Learned: Metal

Things You Need to Know About Metal Treatment

There tends to be a very big difference when it comes to the difference between steel hardness and steel hardenability. Hardenability focuses more on how a given type of metal can harden if it were subjected to extreme levels of heat. When hardening steel, for example, it can only harden as much as the carbon content in it can sustain. During steel hardening, the higher the content of carbon, the harder the metal it will become.

You would also need to remember that the hardenability characteristics tend to highly influence the resultant harness of a metal. Among the goals of hardening a metal includes increasing its ductility as well as toughness. One would also need to remember that metal tempering calls for holding the metal in question at a specific but constant temperature for a given period before cooling it. There is also a need to preheat the metal with the intention of making the carbon to precipitate into carbide particles and at the same time reduce brittleness in the metal in question.

One would also need to know that strengthening of the metal may also call for solid solution hardening, transformation hardening, cold working, among other processes. Precipitation hardening tends to be a perfect match when it comes to aluminum alloy. Cold working, on the other hand, tends to stress the metal’s crystals and deform the metal in question with the intention of making it harder. However, some processes tend to make the metal being worked on hard and brittle calling for more tempering to make it possible to work on the metal in question without splitting or cracking it.

One would also need to remember that the solid solution focus on increasing the strength of the metal and at the same time make sure that the ductility of the same is reduced significantly. Transformation hardening on the other end tends to adjust the ductility and strength of a metal with the intention of meeting some given application requirements. The main intention of metal heat treating is to make sure that the grain structure changes. The concurrent heating and cooling processes tends to focus on changing the metal properties adding value, applicability and durability of the metal in question.

In some cases, the only metal that demands hardening includes the metal at the outermost layer and leave the metal at the core soft. One would need to know that hardening of the outer layer of the metal tends to involve sinking of the metal up to a given depth. One would also need to know about hot isostatic pressing as yet another imperative process. In a case where chrome, titanium and stainless steel needs to be improved, HIP may be used.
