Effects of Flame Hardening on Steel and Iron

As stated in our earlier articles, flame hardening technology selectively heats and hardens parts of a metal workpiece. Imagine the teeth of a spur gear being subjected to the flame, or perhaps it’s the leading edge of a chisel that experiences the focused flame. Looked at from the perspective of the subject steel or iron […]

Annealing Equipment: Significance in Metal Fabrication

Metal fabricators employ numerous tooling stations, which is as it should be because complex geometrical profiles are processed within these expert workshops. Some tools bend, others drill, then, waiting in the wings, there are bandsaw cutters and shop presses waiting. In essence, the workpieces are exposed to enormous stresses. These cold work stresses steal away […]

Cost Friendly Benefits of Flame Hardening as a Heat Treatment for Steel Metals

The flame hardening process is a cost-effective heat treatment technique. Primarily, it’s the high-intensity oxy-gas flame that keeps project expenditure low. The flame hardens localised workpiece areas, so application economy exists right there. Next, the movable flame head controls hardening depth, which is yet another cost-saving benefit. Now that we’ve begun investigating, the budget-centric benefits […]

How Does Non-Ferrous Metal Heat Treatment Work?

Processing variables are confounded when different alloys enter a heat treatment facility. Cooling temperatures and time periods adjust accordingly to metallurgical variances. Likewise, a worked hardened metal part is subjected to ingrained stress. The plastic deformation stress is removed by heat treating the part and making it workable again. These examples apply to steel, but […]

How Does Hardening and Tempering Improve the Strength of Materials?

Material strength isn’t a straightforward property, not when we’re talking about structurally-capable alloys. Yes, a hardened workpiece is stiff, but it could also be brittle. In reality, strength is an amalgamated property, something that combines hardness and material tempering. In using metal solidification technology as our starting point, we’ll explain the importance of hardening, then […]

Stress Relieving and Hydrogen De-embrittlement

Robust metals are often judged on hardness. It’s a term that’s closely related to the stiffness of an alloy, which is all well and good, but what about ductility? What of plastic deformation and tensile strength? A material that’s solely engineered to be stiff is likely to hold its shape, but without elastic deformation, it […]

Heat Treatment: A Critical Process that should not be an Afterthought in Large Engineering Projects

If heat treatment technology has ever been perceived as an afterthought, well, nothing could be further from the truth. This is an essential process regimen, a series of techniques that equips metal parts with tailored material properties. Hardness is usually regarded as the primary reason for altering these already robust alloys, but that’s not always […]

Induction Hardening: Cheaper and Faster for Large Volume Repetition Hardening of Pins, Axles and Shafts Compared to Flame and Case Hardening

Induction hardening technology doesn’t use physical contact. Instead, a series of magnetic fields are projected from a large coil. Workpieces enter the coil, experience this induction effect, and respond by generating surface heat. That workflow suggests a production line of some kind. If so, is its ever-cycling configuration preferred over, say, flame or case hardening […]

Flame Hardening: The Only Suitable Hardening Process for Some Large Unique Components for Large Scale Engineering Projects

The flame hardening process functions as an exceptional surface hardening solution. Its gas-generated flame hardens selected areas on command, then switches tact to heat treat large surface areas, no matter how eccentric the part’s geometry becomes. Let’s indulge in a little discrete analyzing, a look into flame hardening and the method’s gift for processing large […]
