Case hardening is a process of reinforcing the surface of some types of soft metal, making them more durable and tough. This process forms a thin layer of durable metal coating that allows the metal underneath to remain soft. One type of case hardening is carburization, which involves introducing steel items to carbon atoms.  The […]

A heat treatment does far more than just change the physical appearance of metals. It also can modify the properties of them to reach the intended goal. This type of treatment involves heating and cooling the metals at the right temperatures to alter their microstructure. How long the treatment requires depends upon the size of […]

Various properties of metals experience change when they go through a heat treatment. Some changes make the metals more resilient or resistant while others allow them to be reshaped. Even though modern technology has created new methods for this type of treatment, blacksmiths many years ago used to accomplish similar goals by heating and cooling […]

Black oxide is a conversion coating that is suitable for ferrous metals along with copper-based alloys, copper, zinc, stainless steel, silver solder and powdered metals. It accomplishes this through a chemical reaction since it is made of caustic oxidisers and additives. Also, it gives items a lustrous, black appearance and provides some corrosion protection. On […]

The process of induction hardening is for the purpose of hardening the surface of components made from steel or other carbon-alloy metals. Components or parts include a wide assortment of axles, pins, rollers and shafts. As much as 15-mm hardness depths can be achieved. Parts are placed in a special furnace that utilizes a coil […]

Ferrous metals, those that are rich in iron (Fe), often require normalizing. Why should this be the case? Is the grain size really that inconsistent and material-coarse after an iron workpiece has been heat-treated? Actually, yes, the grain size will alter in an iron workpiece if it’s continually processed. This effect worsens when the material […]

A second heat treatment effector exists in an industrial furnace, one that’s sometimes forgotten by the average layperson. Besides the heat source, the gas-fuelled or electrically energized thermal energy flowing evenly around a subject workpiece, there’s the atmosphere inside that sealed chamber to consider. Sometimes, the atmosphere is totally taken out of the heat treatment […]

As a rule, the inner workings of a vacuum furnace are ordinarily composed of a series of sealed firebox chambers. At the centre of this airtight assemblage, a leakproof furnace shell is hooked to an air purging pump. Heat-inducing elements, perhaps made out of fitted graphite or ceramic, provide all workload thermal energies. Further controlling […]

Metals harden when they’re heated, or they become more ductile when they’re heated then cooled at a specific rate. Interestingly enough, metal workpieces change in other ways when cooking in a furnace. With their grains realigning as the thermal energy sends the material into a state of atomic flux, the material becomes more conductive. No […]

Red Hardness, the terminology paints quite a picture. After a steel workpiece slides into a furnace, it soaks up so much thermal that it becomes “red hot.” Alloy microstructures alter when they reach this point. The steel hardens. More importantly, the metal retains this hardness quotient after it cools. That’s an important detail here. Marquenching, […]
