One Minute Mentor: Type W1 Tool Steels

W1 steels are capable of hardening to high surface hardness and soft core, which is useful in some shock applications. They are low-cost tool steels with fair to good wear resistance as carbon content increases. As they are water quenched and have poor dimensional stability, their use is limited to fairly uniform sections with a minimum amount of stress risers; in other applications quench cracking can occur. Figure 1 shows an isothermal transformation diagram for a W1 steel.

Boeing commits $7 million CAD to Vac Aero for vacuum furnace purchase

Boeing announced a $7 million CAD commitment to Vac Aero International Inc., a Canadian aerospace and defence supplier with operations in Ontario and Quebec, as part of the CP8A Poseidon Industrial and Technological Benefits (ITB) program. Boeing will purchase two vacuum furnaces for its Tube, Duct and Reservoir Center in Algona, Washington, where they will heat treat tube and duct assemblies critical to various Boeing airplane programs and select space and defense work. “This ITB investment underscores Boeing’s commitment to Canada following the CP8A Poseidon selection and to modern manufacturing and Canadian small businesses,” said Al Meinzinger, Boeing Canada President. Vac Aero CEO Michael Miasek noted the purchase commitment will allow the company to further expand its Canadian manufacturing capacity.

Wisconsin Oven ships draw batch oven to the military

Wisconsin Oven Corp., East Troy, Wisconsin, announced the shipment of an Electrically Heated Standard Draw Batch Oven (SDB Series) to a United States Military Base. The industrial oven will be used for heat treating aerospace components and features combination-style airflow delivering both horizontal and vertical upward flow for optimal heating rates and consistent temperature distribution. Temperature uniformity of ±5°F was verified at set points of 200°F, 700°F, and 1200°F in accordance with a Class 1 Temperature Uniformity Survey per AMS 2750H. The oven incorporates CAN-style construction with a heavy plate exterior and 6 inches of high-temperature industrial insulation, a 15,000 CFM recirculation system with variable frequency drive, and a UL508A-certified control panel.
