Carbon isn’t a metal. Actually, it’s a sooty black substance, and it’s not that strong. However, appearances can be deceiving, as every engineer knows only too well. Crushed by incredible pressures, carbon crystals become diamonds, which are the strongest naturally occurring substance known to man. In light of this most helpful material feature, by diffusing […]

Flame hardening technology uses a heat treatment methodology that’s reminiscent of old blacksmithing procedures. Instead of electrically powered induction coils, an oxy-fuel gas flame takes care of the workpiece hardening work. Capable of applying a focused heat source, this is a process that’s used to target reduced geometrical outlines. It’s also a heat treatment technique […]

Engineering handbooks describe annealing as a stress reduction process. A workpiece goes into a furnace, is heated to its transformative temperature, then it slowly cools to room temperature. Hard and stressed when going into a heat treatment furnace, the part exits with a softer, plastic-deformable structure. Back with the different grades of steel, there’s more […]

Copious quantities of nickel and chromium bolster a base ferrous structure. That’s what gives Austenitic Stainless Steel its face-centred microcrystalline identity. Infused with a little carbon, the alloy family gains its mainstream mechanical properties. So, what is that austenitic edge? The nickel-based flavouring is clear enough, but we want to know more about its practical […]

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 […]
