Solar Atmospheres of Western PA successfully vacuum heat treated two massive H13 extrusion dies at its Hermitage, Pennsylvania, facility.

The company’s newest high-performing Solar Manufacturing 10-Bar 600 horsepower high-pressure gas-quench vacuum furnace was able to fully harden two huge H13 extrusion dies in successive cycles. The dies, received from two different customers located in Ohio, resulted in an as-quenched hardness of HRC 50-52 using nitrogen as the quench gas. The hollow die was 30” OD x 15” ID x 103” long and weighed 16,000 pounds. The solid die, belonging to a different customer, was 34” OD x 64” long and weighed 14,000 pounds. Post-quench, each component was triple air tempered resulting in a final hardness of HRC 46-48.

“This 10-bar 600 HP high-pressure vacuum furnace allows Solar to attain cooling rates that are inconceivable,” Mike Johnson, director of sales. “Solar is always willing to accept the challenge of vacuum heat treating and brazing any job, no matter the size.”
