Press Hardening Prevents Part Deformation
Press hardening neccessary due to part deformation during the rapid cooling phase induced by quenching
Source: Thermi-Lyon
“Press hardening serves a very specific purpose: to prevent part deformation during the rapid cooling phase induced by quenching. This process improves the performance of steels by giving them a martensitic structure without the need for reworking. Designed for high volume production of parts with complex geometries, press hardening is both highly effective and economical….
This process was initially developed for automotive manufacturers, to process large series of parts with complex geometries. In fact, this method is perfectly suited to the processing of large numbers of parts on a production line: since the cooling cycle is automatically programmed, it can be repeated ad infinitum. What’s more, the circulation of quenching fluid around the part held in the press results in uniform, controlled cooling that can easily be reproduced many times over.”

For heat treated alloys (2xxx, 6xxx and 7xxx series), the letter T and one or more digits are used after the alloy series symbol. The first digit is the most important, as it indicates the type of heat treatment applied to the alloy, while the remaining digits (if provided) indicate heat treatment variants or their modifications. The 7000 series of aluminum alloys have the highest strength of all other aluminum alloy series and are commonly used in aviation since they are held to the highest safety and strength standards.
“T7 denotes the process of solution heat treatment and artificial aging to an overaged state to obtain specific properties, e.g. increased corrosion resistance,” said Tomasz Kaczmarczyk, sales manager of the Aluminum Process and CAB Furnaces Team at SECO/WARWICK. “Sometimes, in addition to the digit denoting the standard heat treatment, an additional digit is used to denote modifications to the given treatment or stress relief procedures. For example, for 7xxx alloys, the symbol T77 denotes retrogression and re-aging. The use of this process improves the alloy’s corrosion resistance, which is so crucial in the production of aircraft parts. The applied technology will allow Taiwan Hodaka Technology to produce high-quality profiles used in the aviation industry in accordance with the AMS standard.”
Piotr Skarbiński Vice President of Aluminum and CAB Products Segment SECO/WARWICK
“The furnace on order equipped with electric heating will process 1500 kg of aluminum profiles with a maximum length of 5500 mm. This is a two-zone solution with a total heating power of 420 kW.
