Metal Hardening The use of this treatment will result in an improvement of the mechanical properties, as well as an increase in the level of hardness, producing a tougher, more durable item. Alloys are heated above the critical transformation temperature for the material, then cooled rapidly enough to cause the soft initial material to transform to a much harder, stronger structure. Alloys may be air cooled, or cooled by quenching in oil, water, or another liquid, depending upon the amount of alloying elements in the material. Hardened materials are usually tempered or stress relieved to improve their dimensional stability and toughness. Steel parts often require a heat treatment to obtain improved mechanical properties, such as increasing increase hardness or strength. The hardening process consists of heating the components above the critical (normalizing) temperature, holding at this temperature for one hour per inch of thickness cooling at a rate fast enough to allow the material to transform to a much harder, stronger structure, and then tempering. Steel is essentially an alloy of iron and carbon; other steel alloys have other metal elements in solution. Heating the material above the critical temperature causes carbon and the other elements to go into solid solution. Quenching "freezes" the microstructure, inducing stresses. Parts are subsequently tempered to transform the microstructure, achieve the appropriate hardness and eliminate the stresses.
Metal Quenching
Material is heated up to the suitable temperature and then quenched in water or oil to harden to full hardness according to the kind of steels.
Material is heated to the suitable temperature for hardening, then cooled rapidly by immersing the hot part is water, oil or another suitable liquid to transform the material to a fully hardened structure. Parts which are quenched usually must be aged, tempered or stress relieved to achieve the proper toughness, final hardness and dimensional stability.
Alloys may be air cooled, or cooled by quenching in oil, water, or another liquid, depending upon the amount of alloying elements in the material and final mechanical properties to be achieved. Hardened materials are tempered to improve their dimensional stability and toughness.
Metal Tempering
Tempering is done to develop the required combination of hardness, strength and toughness or to relieve the brittleness of fully hardened steels. Steels are never used in the as quenched condition. The combination of quenching and tempering is important to make tough parts.
This treatment follows a quenching or air cooling operation. Tempering is generally considered effective in relieving stresses induced by quenching in addition to lowering hardness to within a specified range, or meeting certain mechanical property requirements.
Tempering is the process of reheating the steel at a relatively low temperature leading to precipitation and spheroidization of the carbides present in the microstructure. The tempering temperature and times are generally controlled to produce the final properties required of the steel. The result is a component with the appropriate combination of hardness, strength and toughness for the intended application. Tempering is also effective in relieving the stresses induced by quenching.

Heat treating is an essential phenomenon that is very much needed to manipulate the physical, as well as sometimes the chemical properties of a metal. Heat Treatment of ferrous alloys, involves heating and quenching of the related material at extreme temperatures to get the desired result, such as the hardening and softening of the same material. The size and composition of these crystallites play a pivotal role in determining the overall behaviour of the related metals. The process of heat treatment is designed to manipulate these governing properties of the metal through controlling the rate of diffusion or cooling. Heat treatment is basically used for improving or restoring the manufacturability of a product. Some of the most common forms of heat treatment methods include annealing, hardening, precipitation, case hardening, selective hardening, ageing and stress relieving.

Usage/ApplicationALL TYPE OF APPLICATION

Case hardening is a term used to describe several, more specific procedures which involve the addition of carbon or carbon and nitrogen to the surface of steel. This is done to give the material a hard, wear-resistant outer layer while preserving a softer, more ductile core that is better able to respond to stress without cracking. Case hardening allows manufacturers to work with softer materials and still meet basic requirements for hardness required by an application.
Raw, untreated steel is pliable and soft all the way through — which is not much use if you need a part to be hard at the surface but strong and ductile (or tough) in the middle. Though case hardening is not necessarily a strategy for adding material strength, it does effectively increase the hardness of the outer layer of the material, making it more wear resistant than it would otherwise be.
A steel cutting screw, for example, needs edges hard enough to cut through materials. The trouble is that hard steel is brittle and prone to breaking — so the case hardening provides this cutting edge on the screw while the tougher core holds everything together without breaking.
By diffusing either carbon or nitrogen and carbon case hardening is a suitable strategy for adopting relatively soft materials to applications where a hard exterior is paramount. These are a just a few of the common uses of case hardening:

Fasteners

Bearings and gears

Screw machine parts

Cutting tools

Engine parts

How does case hardening work?
Case hardening works by diffusing carbon or carbon and nitrogen through the surface of a metal by adding them to the atmosphere within a furnace. In case hardening, this is done at high temperatures. With other techniques, such as with ferritic nitrocarburizing, these higher temperatures are avoided to reduce the stress that can accompany phase changes.
Regardless of which specific case hardening technique is used, it’s ultimately a function of diffusion. That is, case depth behaves predictably over time and at given temperatures. In general, carbon and hardness in case hardened materials are high at the surface and gradually decrease with depth.
MMHT approach to case hardening
At MMHT, our furnaces are designed to handle a broad scope of case-hardening applications. We can harden parts up to 48 inches by 36 inches by 36 inches.
We can handle 3,000-pound loads and harden up to 3,800 pounds per hour. We can also meet key automotive requirements, including PPAP.
We have continuous belt furnaces and integral quench furnaces that can generate temperatures of 1750 degrees Fahrenheit in batch furnaces or 1650 degrees Fahrenheit for belt furnaces.
The kind of furnace we use depends on your application. Some parts may have to be heat-treated for hours or even days to accomplish the required case depth, which is why it’s important that your heat treating partner has the capacity to operate 24/7 when necessary.
Our decades of experience, high-tech processes and thorough understanding of metallurgy ensure your parts get cased hardened to your exact specifications.
