Effects of Adding Carbon to Iron during Heat Treatment

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 Methods and Applications

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 […]

What are Austenitic Stainless Steels and Why They Cannot Undergo Heat Treatment?

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 […]

How Does Heat Treatment Affect Steel Grain Structure?

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 […]

Heat Treatment Process of Ferrous Metals

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 Process of Non-Ferrous Metals

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 […]
