As leading industrial furnace manufacturers since 1949, Grieve delivers rugged industrial heat treat furnaces and box furnaces for tempering, hardening, sintering, and firing—including inert atmosphere protection. Our industrial heat treatment furnaces feature precision microprocessor controls, energy-saving insulation, and heavy-duty construction for higher temperatures up to 2200°F.
In a market of standard options, Grieve excels as industrial furnace manufacturers specializing in industrial furnaces for precise heat treating. Our industrial heat treatment furnaces—from compact bench to heavy-duty box furnaces—handle tools, dies, and parts with inert atmospheres to prevent oxidation. Microprocessor controls ensure accuracy, while rugged builds (reinforced shells, Incoloy elements) accommodate severe loads up to 1200 lbs.
High-temp models reach 2200°F for demanding sintering/hardening. Customers choose Grieve for lowest total ownership:, U.S. support, and designs that outlast competitors. Whether standard industrial heat treat furnace or fully customized, we engineer solutions for your toughest challenges.
If you don’t see the ideal oven in our catalog and “off the shelf” won’t work for you, we’ve got you covered. We can design custom industrial ovens and furnaces to your specifications.
Grieve industrial heat treat furnaces support critical processes across industries.
