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 […]

Analysis and Effects of Process Parameters in Induction Hardening

Induction hardening technology employs a refined control setup, with magnetically induced energy patterns acting as a contact-free heat treatment mechanism. A hardening profile is established by the induction station’s electrically manipulated magnetic fields. Science-based principles now gain traction, but what criteria are we hinting at here? A detailed analysis is required to understand the effects […]

Differences between Induction Hardening and Case Hardening

Workpiece hardening is a central part of any heat treatment facilities’ work output, so it’s only logical that several alternative techniques should develop in response to this need for mechanical toughness. Let’s compare two of these popular hardening techniques. Essentially, we’ll be noting the differences that exist between induction hardening and case hardening technology. Processing […]

Stress Relieving is Insurance for Engineering Projects

Large-scale engineering projects use machined metal components to support structural loads. They accomplish this task by accessing the strength of a selected alloy. Unfortunately, strength isn’t the only attribute contained within the metal. The worked part also contains undesirable properties, those incurred by numerous machine stations. Residual stress is the issue. Worryingly, if left unchecked, […]
