What is case hardening?

Case hardening or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material's surface, forming a thin layer of a harder alloy.


Does hardening of steel make it ductile or brittle?

more brittle


What is the maximum hardness can be achieved in EN8 material by hardening process?

Through hardening Process & Polymer quench 20% - As quench Required hardness - 35 - 40 hrc.


Is Surface hardening better method to use or Annealing when these methods are used to manufacture products from ferrous metals?

These are two different methods that are opposites. Surface hardening is used to stiffen a steel. Usually a steel is heated, a catalyst is applied to the surface and then the steel is quenched in an oil bath or waterbath, this hardens the surface of the steel. Annealing on the other hand, the steel is heated and then allowed to cool slowly. This softens the steel and allows it to be drawn or hammered to form a different shape.


The difference between setting and hardening in cement?

SettingSetting begins to occur after the concrete is mixed and even before pouring. The cement in the concrete begins to stiffen after mixed with water. The concrete is beginning to change from liquid form to solid form. During the setting process, the concrete does gain strength, which is the beginning of the hardening process. When the water ingredient is added to the concrete mix, the concrete is still pliable and flexible, sort of a paste. There is two stages of setting: initial and final setting. Initial setting is when the concrete loses it flexibility and begins to harden. Final setting is when the concrete can sustain some load, but still has some moisture within the mixture.HardeningHardening of the concrete is the stage when the mixture gains strength. The cement ingredient begins to attach itself to the aggregate as the water dries off the mixture. The hydration of water is what starts the hardening process. It generally takes five to seven days for the concrete to complete the hardening process. The easiest way to increase the strength of concrete is to add cement to the mixture. The more water used in the mixture, the weaker the concrete and it will also delay the hardening process. Once the concrete has hydrated all the water from the mixture, the hardening process is complete and the concrete is as strong as it will get.

What is toughening process in steel?

One can describe the process of case hardening of mild steel by adding carbon particles while tempering the steel. The outside of steel will become hard which form the case and inside the metal, it remains soft.
