Let’s navigate our way through a passivation process that earns its name by producing a blue-black protective layer around the subjected steel part. The heat treatment technique essentially forms a protective finish around the metal, which is why screws, cutting blades, and even hand weapons can procure that signature “bluing […]
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 […]
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 […]
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? […]
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 […]
