Causes of Quench Cracking in Steel

Quenching is an essential stage in heat treatment technology. The rapid cooling of a hot workpiece stops unacceptable low-temperature processes, including the microcrystalline alterations that would otherwise compromise the procedure. Hardness quotients drop while overall material toughness rises, all by applying a well-controlled quench. However, there are trade-offs to be made when steel parts are […]

Heat Treatment of Martensitic Stainless Steel

There’s nothing simple about heat treatment technology. Even the various microcrystalline forms of steel make the process hard to regulate. Among these forms, martensitic stainless steel ranks as a super-hard alloy. It features a dense tetragonal crystalline structure, but where does this dense configuration occur in the heat treatment process? These and other questions will […]

How Heat Treatment Can Contribute to Steel’s Strength and Weakness

Counterintuitive consequences have been known to compromise heat treatment work. By way of illustration, steel strengthening operations should logically produce strong workpieces. However, there are times when these mathematically predictable results go out the window. Are there strange laws of probabilities in effect? Or is there a straightforward reason for heat treatment induced weakness? Uncertainty […]

Flame Hardened Medium Carbon Steel Qualities

While medium carbon steel clearly isn’t as hard as a high-carbon alloy, those lenient mechanical qualities can be enriched. By exposing the steel to flame hardening equipment, a heat treatment technique that uses a focused cone of combusted gas, we fortify the material and reinforce its generally weaker microcrystalline bonds. A mild steel workpiece is […]

A Review in the Fundamentals of Heat Treating

Much has been covered in past posts. The basics of heat treatment technology formed a foundation, then that groundwork received new and interesting additional levels. They dealt with surface hardening issues, quenching anomalies, and all manner of tricky alloy manipulating techniques. Now we’re reinforcing the groundwork and reviewing the fundamentals of heat treating science, plus […]

Gas Nitriding and Its Effects on Steel

This post will address the gas nitriding process and its effects on steel. Essentially, we’ll be looking at a heat treatment technique that addresses alloy hardening concerns and the need for a process that attenuates the corrosion rate of this ferrous-heavy metal. But first, considering the importance of this subject, just why is gas nitriding […]

Comparing Induction Hardening and Case Hardening

On one side of this comparative guide, induction hardening technology employs a strong electromagnetic field as the heat treatment engine. On the other side, a similarly potent case hardening station is busily armouring the surface of a newly arrived workpiece. Both methods harden exterior surfaces. Case in point, flame hardening equipment is incredibly selective, but […]
