Articles on heat treatment, hardening and metallurgical processes for Australian manufacturers.
Undergoing heat treatment, a steel workpiece warms until it’s almost red-hot. Engineers monitor the process, compare the actions taking place in the furnace to specially formulated graphs, and the metal...
Read MoreHere’s a case study where a steel workpiece was hardened in a cutting-edge furnace. The process is locked in, and it has been exhaustively tested, so the repeatability factor is...
Read MoreHeat treated metals are undeniably hard and rigid. Still, their dimensional parameters can and often do change when their microcrystalline matrices are exposed to massive quantities of thermal energy. The...
Read MoreTransforming metal workpieces with intense levels of thermal energy, heat treatment processing manipulates microstructure compositions until a desired mechanical or physical property is achieved. However, even the finest operation can...
Read MoreModern alloys are among the toughest materials known to man. A selected alloy, perhaps destined to become a key part in a massive construction project, can handle massive loads, yet...
Read MoreQuenching 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....
Read MoreThere’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...
Read MoreCounterintuitive 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...
Read MoreWhile 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...
Read MoreMuch 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...
Read MoreBlack oxide is a pleasing surface conversion coating. As stated in past articles, the process dresses steel and other select alloys with a corrosion resistant skin. Although mild in nature,...
Read MoreThis 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...
