In the aerospace industry, heat treating is an essential step in the manufacturing process. Stress reduction on metal parts to improve the strength and fatigue life of aircraft components is critical to ensure parts stand up to the demands and specifications of aerospace applications. Every aircraft we see in the sky today contains precision-made parts and systems that have undergone heat treatment, whether it’s engine brackets, landing gear, bearings, gears and rods, fuselage, frame parts, brakes, or cooling systems.

Sometimes, however, those involved in modern heat treating processes, such as Metlab, based in Wyndmoor, Pennsylvania, and DELTA H Technologies, LLC, located in Carroll, Ohio, also expand their capabilities and apply their expertise to heat treating parts of historic aircraft in order to restore them to their former glory.

Lockheed L1649A “Super Star”

A DELTA H heat treating system is now being used in a project to make a Lockheed Constellation airworthy. The science of heat treating has not changed, therefore, a state of the art heat treating system is fulfilling the requirement to repair damaged antique aircraft and parts. Using the DELTA H heat treating system to make this aircraft flight-worthy ensures that the aircraft will be in compliance with AMS2750E.

The Lockheed Constellation is an important piece of U.S. aviation history, a plane used for civilian and military transport, as well as a presidential aircraft for U.S. President Dwight D. Eisenhower.

Ryan ST-A (Aerobatic) training aircraft circa. 1934

Classic Metalcraft recently turned to Metlab for the heat treatment of a newly fabricated structural bulkhead for a Ryan ST-A historic aircraft (circa.1934). Ryan Sport Trainers were the aircraft of choice for sport pilots, flying schools, and the military of other countries.

“The most difficult part that needed to be fabricated was the #2 bulkhead,” said David Paqua of Classic Metalcraft. “Not only is it tough to replicate without heavy pressing equipment, but it requires heat treating by a knowledgeable firm to prevent distortion.”

Bulkhead component prior to heat treating

The bulkhead component is a structural piece fabricated with 4130 steel and located just forward of the instrument cluster, where it bears significant stress. Metlab’s heat treating capabilities ensured that the shape integrity of the part was maintained as well as the aerodynamic characteristics of the aircraft.

A Dozen Quick Heat Treat News Items To Keep You Current

The heat treat industry is one of people transitioning and companies executing business, achieving goals, and receiving acknowledgments. Heat Treat Today offers News Chatter, a feature highlighting representative moves, transactions, and kudos from around the industry.

Personnel and Company Changes and Moves

D. Scott MacKenzie, PhD., vice-president, IFHTSE

    • At the Executive Council meeting of the International Federation of Heat Treating and Surface Engineering (IFHTSE), D. Scott MacKenzie, PhD., was elected to serve as vice-president for a two-year term (January 1, 2018, to January 1, 2020). MacKenzie, a research scientist in metallurgy with Houghton International, Inc., in Valley Forge, Pennsylvania, has been the ASM representative to IFHTSE since 2015.

      New team members at Paulo: (left) Mike Neumann, plant manager, Kansas City facility; (right) Kathy Neumann, director of corporate safety
    • Paulo has announced two additions to their Kansas City team. Mike Neumann, who brings 20 years of progressive experience in the heat treating industry, joins Paulo as the plant manager for the Kansas City location, which serves the automotive/heavy truck, aerospace, and railway industries and has a diverse offering of heat treating equipment. Kathy Neumann, who has extensive experience managing multi-plant safety programs for commercial heat treatment and traditional manufacturing companies, joins Paulo as the Director of Corporate Safety based at the Kansas City facility.
    • The Metal Powder Industries Federation (MPIF) has announced that Arthur (Bud) Jones, of Symmco, Inc., Sykesville, Pennsylvania, has been appointed president of the Center for Powder Metallurgy Technology. Jones succeeds Jeff Hamilton of American Axle & Manufacturing, Inc (AAM) – Powertrain, who had completed two terms.

      William Jones, owner of Solar Manufacturing, Inc.

      Solar Manufacturing Incorporated, an industry leader in manufacturing advanced industrial vacuum furnaces, is relocating its headquarters to Sellersville, Pennsylvania. The Sellersville Borough Council recently granted unanimous preliminary and final approval for the new building located on a combined 8.5 acres; the manufacturing area will occupy 40,000 square feet of the facility with an additional 17,500 square feet of office space. There is the option of an extra 22,500 square foot addition to the manufacturing building in the future. "I am thrilled to see this project moving forward for our new headquarters.  This new facility will provide us the space we need to grow and consolidate all our staff in one facility," said William Jones, who along with his wife, Myrtle Jones, owns Solar Manufacturing, Inc.  Gorski Engineering is scheduled to begin breaking ground for the new eight million dollar facility in the spring of 2018, with completion and occupancy later that fall.

       

       Equipment Transactions

    • Advanced Heat Treat Corp. (AHT) has purchased a gas nitride unit to expand its capacity for UltraGlow® Gas Nitriding and UltraOx® surface treatment solutions at its facility in Waterloo, Iowa. This new, large, state-of-the-art gas nitride/high temperature unit will also allow increased capacity of currently offered services including gas ferritic nitrocarburizing (FNC) and stress relief.
    • Aerospace heat treating manufacturer Delta H Technologies LLC of Columbus, Ohio, recently supplied a high-temperature heat treating furnace to a major aircraft MRO. The thermal equipment is capable of heat treating titanium, A286, PH stainless steel, and tool steels in an air or argon atmosphere. "This system complements our popular dual chamber aerospace heat treat (DCAHT serie) furnaces for aircraft aluminum," said Ellen Conway Merrill, vice president of Delta H. "Specifically, it provides a complete heat treating furnace system designed exclusively for aircraft MRO back shops, military, aircraft OEMs, and parts manufacturers."
