We’re celebrating getting to the “fringe” of the weekend with a Heat Treat Fringe Friday installment: a project that targets reducing the environmental impact of the bright annealing process. Learn more about this EU-funded initiative that is expected to impact industries using high-hydrogen-content atmospheric gas.
While not exactly heat treat, “Fringe Friday” deals with interesting developments in one of our key markets: aerospace, automotive, medical, energy, or general manufacturing.
Energy efficiency, specifically reducing the environmental impact of the bright annealing process in seamless stainless steel and nickel alloy tube production, is the goal of a new European Union-funded initiative. The recently launched LIFE H2ReuseProject seeks solutions for hydrogen recovery and reuse.
The project, coordinated by DMV (Cogne Group, formerly Mannesman Stainless Tubes) in partnership with Tenova, is expected to impact industries using high-hydrogen-content atmospheric gas, which could apply the project’s results to reduce their carbon footprint, optimize resource use, and lower operating costs.
In the bright annealing process, 100% hydrogen is used in high-temperature furnaces to produce high-performance tubes with superior surface quality, corrosion resistance, and durability. Currently, hydrogen is flared after each production cycle, leading to significant waste. The LIFE H2Reuse project aims to address this issue by developing two innovative technical solutions: recovering the wasted hydrogen from the annealing process and reusing it as fuel in radiant tubes working 100% of hydrogen. This approach represents a market-first innovation, as the recovery of atmospheric gas for reuse in industrial processes is not yet commercially available.
While hydrogen burners are already on the market, they remain in a developmental phase. The initiative will focus on enhancing their efficiency and effectiveness in real-world industrial environments. The project’s expected outcomes include significant reductions in carbon footprint, energy consumption, and resource waste, all of which will be rigorously tested to demonstrate their technical, environmental, and socio-economic benefits.

Japanese Steel Giants Pursue Government Allocated Green Funding
“Two of the largest integrated steel producers in Japan, Nippon Steel and JFE Steel, have applied for government funding allocated through the new Green Transformation Promotion Act (GX) to advance research and development in decarbonizing operations. JFE Steel is seeking funds to build a new large electric arc furnace (EAF) to replace blast furnace No. 2 at West Japan Works (Kurashiki). The company expects the EAF to be commissioned between 2027-2028. Blast Furnace No. 2 at the plant underwent a re-lining in 2003. JFE usually performs such maintenance after about 25 years of operation, so the next one is due in 2028. However, JFE Steel hopes that the new electric arc furnace will be operational by then, so the unit can be shut down. West Japan Works currently operates three blast furnaces with a steel output of about 8Mt/yr.”
“Tresky Automation announces the latest addition to its contract manufacturing machinery. Customers will now benefit from a state-of-the-art vacuum brazing furnace and a powerful sintering press with a maximum pressing force of up to 15 kN. The new equipment enables Tresky to offer additional manufacturing technologies, which is particularly beneficial for demanding applications in the fields of photonics, optoelectronics, hybrid bonding, microelectronics and power electronics. The new vacuum brazing furnace offers the possibility to produce material bonding under controlled conditions with nitrogen (N2) or formic acid (HCOOH). This process effectively reduces voids, as the vacuum allows air or process residues to escape during the preheating and melting phase of the solder. The result is virtually void- and flux-free solder joints that are characterized by high reliability.”
Technology Alliance Enables Growth in Refractory Products Manufacturing
“RATH and REFRATECHNIK announced the launch of a long-term technology alliance. The goal of the ambitious partnership is close collaboration in the development and manufacture of refractory products for glass melting plants in the glass industry.
