What do visitors want to see when they stop by a heat treatment facility? Watching from behind a thick glass plate, they enjoy the sight of an orange-hot workpiece as it is processed in a furnace. Next on their agenda, they want to experience the explosive sizzle that’s discharged as that workpiece is quenched in […]

Old Smithy sheds are viewed as our heat treatment grandfathers. They didn’t install massive furnaces, but there was always that flickering red flame. The hot coals burned bright in primitive townships. Then, at day’s end, there would be that rattling hiss as a forged part was quenched in water. And water is still a quenching […]

As the temperature rises in a heat treatment furnace, strange transformations occur. In steel workpieces, the grain structure of the component changes size. Alternatively, new grains form. They undergo phase transformative processes. There’s carbon in the mix, too. As those phase changes take place, the alloy-strengthening element becomes more soluble. The carbon diffuses, so the […]

Ferrous metals are those that contain iron. Laced with carbon and other exotic elements, iron is a durable, structurally capable alloy. It exudes a polished finish when formed into stainless steel, becomes malleable and machine-formable when forged as mild steel, and it even demonstrates a high measure of corrosion resistance when mixed with nickel. Endlessly […]

Heat treatment science employs an equal opportunities approach to the field of metal strengthening. That’s another way of saying the techniques used here aren’t just used to harden ferrous workpieces. Indeed, full-service heat treatment facilities toughen soft non-ferrous components, too. Needless to say, though, a different set of processing standards are implemented when a non-ferrous […]

Salt Case Hardening, the term sounds so exotic. The knowledgeable heat treatment professional knows exactly what’s happening when the technique is applied, of course. Meanwhile, for the novice engineers out there, it’s possible to infer the case hardening approach used here, perhaps by focusing on the saltiness of the procedure. Sit tight for the next […]

In this heat treatment technique, a counterintuitive reaction is seemingly encountered as a metal workpiece is heated and held at a predetermined furnace temperature. Remarkably, instead of hardening the alloy, the procedure softens the part and makes it more ductile. That thought goes against the grain. Well, it seems to, but this is the intended […]

A problem-solving guide for black oxide coatings, that’s the direction this article is taking. The finish should be oily black. Putting a tick in that checkbox, the coating should also be moderately corrosion resistant. Only, the inspector’s pen is wavering. There’s an issue with the ebony-hued conversion coating. Spotting problems are apparent, as are strange […]

There’s no end to the number of metals out there, all of which serve different roles in countless applications. Selecting the materials, it’s up to a metallurgically talented sourcing expert to choose the material classifications that satisfy a customer’s demands. Heat treatment technology then further processes the metal so that it has all of the […]

Sintered components are produced when fine metallic powders are compacted inside special cavities. As high pressures cause densification, heat is added. Therefore, as a process precursor, this operation employs a finite amount of heat treatment toughening right at the end of the product forming procedure. However, if the tightly packed, materially diffused particles still don’t […]
