News From Abroad: Initiatives, Processing for a Better World

/ AUTOMOTIVE HEAT TREAT NEWS, HEAT TREAT NEWS, MANUFACTURING HEAT TREAT NEWS, QUENCHING NEWS

In today’s News from Abroad installment, we highlight processing and initiatives that aim to improve operations and improve sustainability. Read more about a method used in the production of parts with complex geometries; a venture to create the world’s first fossil-free, ore-based steel with renewable electricity and green hydrogen; and a production plant that will generate around 9,000 tons of green hydrogen a year to be used for the production of carbon-reduced steel.

Heat Treat Today partners with two international publications to deliver the latest news, tech tips, and cutting-edge articles that will serve our audience — manufacturers with in-house heat treat. Furnaces International, a Quartz Business Media publication, primarily serves the English-speaking globe, and heat-processing, a Vulkan-Verlag GmbH publication, serves mostly the European and Asian heat treat markets.

Press Hardening Prevents Part Deformation

"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."

"Launched in 2016 as a joint venture owned by SSAB, LKAB, and Vattenfall, with support from the Swedish Energy Agency, HYBRIT aims to create the world’s first fossil-free, ore-based steel with renewable electricity and green hydrogen.

This involves shifting from coal-powered blast furnaces that use coal as a reduction medium to a direct reduction process using hydrogen produced via renewable energy. The first HYBRIT pilot plant in Luleå, Sweden, began operations in 2020, with commercial-scale production targeted by 2027.

Kanthal is proud to have contributed to HYBRIT’s groundbreaking journey by developing an electricity-based process gas heater for the hydrogen-based direct reduction process under the name Prothal®. This project showcased the feasibility of fossil-free industrial heating solutions and laid the groundwork for scaling up these technologies to meet the steel industry’s future needs."

"On February 12, 2025, the cornerstone was laid for one of the largest production plants for green hydrogen in the whole of Europe.

[Beginning in] 2026, the plant will generate around 9,000 tons of green hydrogen a year to be used for the production of carbon-reduced steel. This will mark the start of the industrial use of hydrogen in SALCOS®-Salzgitter low CO2 steelmaking. SALCOS® is aiming for virtually carbon-free steel production. The 100 MW electrolysis plant will be supplied on an EPC basis by the international technology company ANDRITZ, using the pressurized alkaline electrolysis technology of HydrogenPro."

US Heat Treater Adds Furnaces, Marquenching Capabilities

/ AEROSPACE HEAT TREAT NEWS, ATMOSPHERE AIR FURNACES NEWS, MANUFACTURING HEAT TREAT NEWS, QUENCHING NEWS

A commercial heat treating company recently added new furnaces and process improvements to its operations in order to serve manufacturers in advanced industries, including aerospace and defense. The improvements include a high-temperature oxidation furnace, a fully rebuilt furnace, and the expansion of marquenching capabilities.

Phoenix Heat Treating, based in Phoenix, AZ, has introduced a high-temperature oxidation furnace specifically designed for space components. This equipment has a maximum operating temperature of 1975oF and operates in an air atmosphere, providing the thermal stability and precision needed for the demands of aerospace applications and to serve the evolving needs of the space industry.

A fully rebuilt furnace has been reactivated in the company’s production lineup. This furnace is tailored for processing primary long Inconel 718 and A286 age cycles. With a maximum weight capacity of 2000 lbs., it handles heavy and complex loads with a goal of ensuring consistent and reliable results for critical nickel-based alloy applications and improving efficiency and capacity by increasing the number of Inconel 718 cycles per week.

Marquenching operations are also seeing an upgrade as materials have been ordered to increase load sizes from 25 lbs. per load to 250 lbs. per load. Expected to be complete by mid-February, this enhancement represents a tenfold increase in capacity, allowing Phoenix Heat Treating to achieve faster turnaround times and larger batch processing capabilities.

Additionally, a state-of-the-art freeze/temper unit has been brought online. This equipment is capable of reaching temperatures between -270oF and 200oF and will be a part of the company’s aluminum thermal cycling processes, enabling precise control over temperature profiles for optimal material performance. The new unit’s capacity is roughly double that of the previous maximum reached and will allow Phoenix to handle significantly larger loads and meet growing customer demand.

Manufacturer in Energy Expands with Heat Treat System

/ ATMOSPHERE AIR FURNACES NEWS, ENERGY HEAT TREAT, NITRIDING NEWS, QUENCHING NEWS

A manufacturer for the energy industry has recently announced the installment of a roller hearth furnace system. The heat treat system is comprised of two (2) box furnaces with quench tanks, a dual directional load transfer car, four (4) companion draw batch ovens, and two (2) stationary load/unload tables.

The system from Lindberg/MPH has a maximum operating temperature of 1850°F for the box furnaces, which are designed for nitrogen-based atmosphere applications. The load space dimensions of the box furnaces are 48” W x 96” D x 36” H, with larger internal chambers to provide clearance for baskets or fixtures. A snake chain pusher assembly with a dual-directional pacecar is used by each furnace to transfer the loads from the chamber to the pneumatically operating quench elevator deck.

The glycol quench tanks are designed for quick and uniform quenching, featuring an immersion oil heater and an externally mounted air-to-quench media heat exchanger. The tanks’ agitation systems include four agitators with draft tubes. The gross load capacity of the car is 10,000 lbs., and it travels linearly in front of the equipment on two embedded floor rails.
