What is Oxidation in Heat Treatment?

Just as a refresher, what is heat treatment technology? Certainly, the exposure of a metal part to heat changes its material and mechanical characteristics. And those changes occur over time. That controlled thermal treatment sequence can even be dramatically curtailed by quenching the metal workpiece. What about material oxidation in heat treatment, though? Where does […]

High Carbon Steel Hardening Process

Carbon is the element upon which all of life is founded. Also, in heat treatment technology, carbon is the primary alloying element in the steel hardening process. Not surprisingly, there are variations on this theme. For example, high carbon steel is a dense alloy, but it’s also a brittle metal. Let’s follow this hardening process […]

What is Austempering?

Today’s journey through heat treatment technology looks at Austempering. As always, we’re industriously seeking the best, most cost-effective way to improve the mechanical and physical characteristics of a workpiece. More than this, we’re using specific engineering methods to ensure the workpiece absolutely exhibits the traits that have been set in stone by a client. So […]

Low Carbon Steel Case Hardening Process

It’s tough to case harden low carbon steels. Simply put, more carbon equals more hardness, a feature that even the casual observer can appreciate. One solution to this processing puzzle is to introduce more carbon. In essence, the low carbon surface is infused with a supplementary carbon source. Consequently, as the additional carbon is artificially […]

Tips for Finding Leaks in a Vacuum Heat Furnace

Vacuum heat furnaces perform expeditiously as atmosphere controlled heat treatment chambers. Drained of process-influencing oxygen and filled instead with an inert gas, the furnace stops scaling, stops parts discolouration, and generally improves the mechanical and physical characteristics of any processed workpiece. What happens if this sealed chamber develops a leak? The vacuum is tainted and […]

A Few Do’s and Don’ts of Hot Zone (Heat Treatment) Maintenance

Do’s and don’ts guides are an engineer’s best friend. They’re an objective instruction tool that helps system architects and fabricators to navigate processing minefields. In that regard, hot zone maintenance procedures employ a highly organised sequential approach. That systematic methodology begins with a pre-processing phase, a maintenance checklist that governs the heat treatment operation before […]

Heat Furnace and the Importance of Temperature Uniformity

Does a factory full of furnaces look like some industrial hell? In point of fact, nothing could be further from the truth. Science-lab accuracy and high-tolerance engineering exactitude rule every processing stage. In those heated furnaces, temperature uniformity is a beyond critical quality, one that comprehensively eliminates heat treatment inconsistencies. Let’s really draw a line […]
