TMK’s Seversky Pipe Plant awarded SMS group the final acceptance certificate for a heat-treatment line for tubes and pipes at its Polevskoy site in Russia. The line has an annual capacity of up to 300,000 tons of pipes with diameters between 168 and 370 mm (6.6 and 14.5 inches), a wall thickness of up to 40 mm (1.5 inches) and lengths of up to 13.5 meters (44.3 feet). The line is able to process small batch sizes and different product groups in a cost-efficient manner.

This coordinated Nadcap system results in a standardized approach to quality assurance and a reduction in redundant auditing throughout the aerospace industry.

Rapid phase transformation and high thermal gradients that occur during quenching can cause distortion, which can lead to costly hard machining and rejection.

Hot isostatic pressing (HIP) is a process used to eliminate internal voids and defects such as porosity in castings, additive-manufactured (AM) parts and MIM parts to achieve a 100%-dense material.

UCM 4D Quench is a vacuum heat-treatment system for individual quenching of component parts such as gears, shafts, bearing races and rings.

The use of vacuum technology for carburizing has always shown the most potential for improving the manufacturing process by reducing both processing time and the number of manufacturing steps required to produce a part.

Nucor Steel has chosen Danieli to supply a new quenching and self-tempering system to be installed at its mill in Marion, Ohio. The quenching and self-tempering process improves the mechanical properties of deformed bars, particularly yield strength, using billets with lower alloy content. The result is a product with final technological characteristics equal to or better than those obtained by low-alloyed/micro-alloyed steels.

The Jominy end-quench test is used to measure the hardenability of a steel, which is a measure of the capacity of the steel to harden in depth under a given set of conditions. This article considers the basic concepts of hardenability and the Jominy test.

Baker Furnace, a division of Thermal Product Solutions, installed a quench tank for a commercial heat treater as part of its aftermarket services. The company had two quench tanks (one hot water and one cold water) and three drop-bottom furnaces and needed a third quench tank to optimize quench loads per day. The quench tank has three impellers capable of 27,000 GM on a 15,000-gallon tank. This style of agitation allows for thick, large castings to dissipate heat faster.

An induction process consists of an induction power supply that passes a high-frequency alternating current (AC) through an inductor.
