Metal Heat Treating Furnaces
Metal Heat Treating Furnaces
Heat Treat Furnaces / Aging Ovens meeting AMS 2750 and NADCAP specifications
Heat treating is a thermal process used to alter the physical properties of metals. By changing the rate of heating and cooling, the mechanical behavior of metals is easily manipulated. The different processes include aluminum solution heat treating, precipitation / age hardening, annealing, aging, quenching, assaying, tempering and hardening. Interesting: Aluminum alloys are soft after quenching, ferrous materials become briddle. Both groups require another heat treat process after quenching.
View the Bench Top Assaying, Hardeningor Tempering Heat Treat Furnaces Specification Sheets with a full description of features and options and then either call to talk to a Keith company specialist or email to request prices, additional furnace specifications and delivery.
Keith furnaces are built to NFPA 86 specifications and meet pyrometric requirements such as NADCAP, AMS 2750 E (Aerospace Material Specifications) and MIL Spec specifications. The different specifications outline in detail the different requirements for thermal processing systems of each alloy. Selecting the furnace class for temperature uniformity and instrumentation type, which guides the design of the system, these specifications also regulate inspection cycles and inspection precision. The class of heat treatment furnace (1-6), type of instrumentation (A - E), quench delay time (5-15 sec) and quench medium temperatue for solution heat treatment are based each alloys process heat treat specification (examples: AMS 2770, AMS 2771, AMS 2772, BAC-5621, RPS-953, MIL-H-6088). These specs are verified by temperature uniformity surveys (TUS) & NADCAP AC 1702 audits.
