Ovako Steel’s 2018 investment in a vacuum tank degassing (VTD) facility is a critical development for the Smedjebacken mill. Removal of hydrogen by a state-of-the-art vacuum process now enables Ovako to address the needs of forgers that require high-performance, reliable and cost-effective steel for demanding applications such as those in the automotive industry.
Two companies joined forces to greatly enhance productivity in heavy milling and crankshaft machining. Their combined efforts resulted in solutions to improve throughput and reduce costs considerably.

Greenleaf Corporation of Saegertown, Pa., is a supplier of industrial cutting tools. The company specializes in the manufacture of high-performance carbide and ceramic inserts, tool-holding systems and custom-designed tooling solutions.
Can-Eng Furnaces International Ltd. received a contract from a Tier 1 manufacturer of forged suspension components for a system that will produce lightweight forged-aluminum parts for passenger vehicles. The system includes a pre-forging rotary-hearth aluminum heating furnace, water quench and continuous aging furnace. The equipment will be integrated into an automated forging cell that includes specialized material-handling components and advanced controls.
Viking Analytics, a Swedish provider of advanced analytics solutions for predictive operations, and Bharat Forge Kilsta, a Sweden-based supplier of forged components, began collaborating in a data-driven production quality project. In the coming months, Viking Analytics will prepare an assessment of the data collected by sensors installed in the oven that heats steel rods used in the production of crankshafts and front axle beams for heavy-duty vehicles. In Bharat Forge Kilsta’s Karlskoga plant, the forged steel is first heated in an induction oven, whose temperature varies according to different steel grades and products. If a disruption occurs, the oven must be adjusted to keep the metal at a constant temperature. This process is currently performed manually, which sometimes causes human-related deviations in the proper temperature-level records.
Berkshire Hathaway Inc. recently announced a $9.8 billion write-down for its Precision Castparts Corp. (PCC) unit. PCC’s aircraft components business has been ruined by the COVID-19 pandemic, forcing the company to reduce its workforce by 10,000 this year. PCC reported a $78 million pre-tax loss in the second quarter of this year, compared with earnings of $481 million in 2019. Berkshire Hathaway bought PCC in 2016.
Allegheny Technologies Inc. (ATI) announced a realignment of its business segments to further enhance its position as a leading specialty materials manufacturer and to accelerate sustainable long-term profitable growth. Starting with first-quarter 2020 financial results, ATI will report in two business segments: a streamlined High Performance Materials & Components (HPMC) segment and the new Advanced Alloys & Solutions (AA&S) segment.
Forged Components Inc. (FCI) of Humble, Texas, announced the acquisition of Western of Texas Forge & Flange Co. (WTFF) in the fourth quarter of 2019. WTFF manufactures pipe flanges and forgings to standard and custom sizes to the oil and gas exploration and production, oil refining and processing, petrochemical, chemical, and power-generation industries. Kountze, Texas-based WTFF will continue to operate under its current name.
BorgWarner Inc. and Delphi Technologies PLC entered into a definitive transaction agreement under which Auburn Hills, Mich.-based BorgWarner will acquire Delphi Technologies for approximately $3.3 billion. The acquisition will strengthen BorgWarner’s power electronics products, capabilities and scale. Combining with London-based Delphi Technologies will enable BorgWarner to maintain flexibility across combustion, hybrid and electric propulsion. The combined company will serve light- and commercial-vehicle manufacturers and the aftermarket.
Forge shops can increase productivity and reduce costs in hot-forging and heat-treatment processes using synthetic lubricants and/or protective coatings. Hard coatings cold-welded onto high-wear areas of dies or anti-oxidation coatings painted directly onto forging billets can help.
Protective coatings continue to play a major role in increasing productivity and reducing costs in hot forging and heat treatment. This paper presents details and successful case studies of three such protective coatings.
Premier Forge Group, a portfolio company of Wynnchurch Capital, acquired California Amforge Corp. Located in Azusa, Calif., Amforge manufactures closed-die, upset and rolled-ring forgings for the aerospace, defense and oil-and-gas industries. The company supplies critical components for both fixed and rotary wing aircraft and engines in military and civil applications. Located in Portland, Ind., and Lebanon, Ky., Premier Forge provides high-value, complex forgings for OEMs in a range of markets. The company’s capabilities include comprehensive forging processes complemented by in-house design and engineering, product machining and heat-treating services.
