How Heat Treatment Can Affect Welded Joints
Much though engineers wish the opposite were true, heat treatment work can weaken welded joints. Since welding equipment uses thermal energy to fuse parts together and add filer metals, the...
Read MoreCommon Induction Hardening Problems and Resolutions
Just as a reminder, induction hardening technology is used to enhance the toughness and fatigue resistance of carbon steel parts. Components to be heat treated are placed inside a furnace,...
Read MoreApproximate Soaking Time for Hardening, Annealing, and Normalizing Steel
Three primary heat treatment phases break down into multiple branches and subsets. First comes the heating, the stage that thermally alters a part’s microcrystalline structure. As the work comes to...
Read MoreRisk Management in Heat Treatment
Not every processing pipeline in a heat treatment facility is mechanically oriented. Away from the vacuum-sealed furnaces and quenching tanks, the alloy hardening work is viewed from a different perspective....
Read MoreVacuum Furnace Quenching System: The Role of Gas Quenching in Heat Treatment
Using gaseous quenching mediums, new and improved cooling models are rippling through the heat treatment sector. However, not just any old cloud of gas is going to suit this role....
Read MoreEffective Precision Straightening of Thin-Walled Tube Metals
Thin-walled tube metals are employed in a wide number of large-scale applications. Whether the tubes find their way into pipe networks or aerospace frames, they need to exhibit one key...
Read MoreCauses of Steel Warping During Heat Treatment and How to Prevent Them from Happening
Ideally, heat treatment work affects the microcrystalline structure of a steel part. In the furnace, then cooled gradually or quenched suddenly, the physical properties of the steel alters. The processed...
Read MoreLiquid Nitriding vs. Gas Nitriding in Case Hardening: What is the Difference?
The next two heat treatment processes are similar. They both use a nitrogen-rich substance to harden soft metal workpieces. But, as the post title implies, the nitrogen arrives in two...
Read MoreControlled Gas Nitriding Process and Its Benefits to Low Carbon Steel
Atmospheric control is a powerful tool in a heat treatment engineer’s metal hardening armoury. For example, by adding gaseous nitrogen to a furnace, the gas nitride hardening effect is initiated....
Read MoreEffects of Adding Carbon to Iron during Heat Treatment
Carbon isn’t a metal. Actually, it’s a sooty black substance, and it’s not that strong. However, appearances can be deceiving, as every engineer knows only too well. Crushed by incredible...
Read MoreFlame Hardening Methods and Applications
Flame hardening technology uses a heat treatment methodology that’s reminiscent of old blacksmithing procedures. Instead of electrically powered induction coils, an oxy-fuel gas flame takes care of the workpiece hardening...
Read MoreWhat are Some of the Different Types of Annealing Process of Steel?
Engineering handbooks describe annealing as a stress reduction process. A workpiece goes into a furnace, is heated to its transformative temperature, then it slowly cools to room temperature. Hard and...
