Wire ropes for haulage purposes are usually made from carbon steel wires ranging from 0,35 to 0,5% carbon, and before drawing the material is subject to a heat-treatment known as patenting.. Patenting consists of passing the wire through tubes in a furnace at about 970 o C. This high temperature treatment produces uniform austenite of rather large grain size.
3.1. Effect of Heat Treatment on Mechanical Properties The effect of heat treatment (annealing, normalising, hardening, and tempering) on the mechanical properties (ultimate tensile strength, hardness, toughness, percentage elongation, and percentage reduction) of the treated and untreated samples is shown in Table 3. The tensile
Jun 05, 2019· For example, to achieve the best combination of high tensile strength, high fatigue and stress-rupture life for use in aerospace applications (often referred to as high-strength 718) such as rotational parts, turbine blades, bearings and fasteners, a somewhat more complex heat-treatment cycle is recommended.
This article is about the difference between heat treatment, annealing, and tempering. The article explains the effects of annealing and tempering on the physical properties of metals, such as ductility, strength, and brittleness. Also explained are the methods for annealing and tempering, as well as the microscopic changes that heat treating causes.

Jan 12, 2015· Alpha-beta (α – β) alloys –strengthened by heat treatment; medium to high strength, high formability, good creep resistance (but less than most alpha alloys), alloys with beta content less than 20% are weldable. The most familiar alloy in this category is Ti-6Al-4V.
If quenching is required as part of aluminum heat treatments, then it is critical to quench the part as soon as it comes out of the heat treatment furnace. A delay of more than 15 seconds can be very detrimental. Having a quenchant tank as close as safely possible to the heat treatment furnace is wise.
About Heat Treating & Heat Treat Furnaces. Heat treating (or heat treatment) broadly refers to a group of thermal processes in industrial and metalworking applications used to intentionally alter the physical, and sometimes chemical, properties of a material (usually a metal).
The present invention relates to a heat treatment furnace. More specifically, the invention is intended to provide a heat treatment furnace for a treatment performed by keeping metal at a high temperature for a certain period and then cooling rapidly the same, which achieves a reduction of running cost and an increase in cooling speed.

Also this furnace can be used with special gas atmospheres in order to carburize, or nitride the part.
High degree of automation: The degree of automation of the vacuum heat treatment furnace is higher because of the heating, cooling and other operations of the metal workpiece, which requires more than a dozen or even dozens of actions to complete. These actions are carried out in a vacuum heat treatment furnace and are inaccessible to the operator.
