91´«Ã½ Offers 2000°C (3632°F) Processing
91´«Ã½, Inc., a commercial heat treater, now offers vacuum furnace processing up to 2000°C.  Applications processed in the 12″x 12″x 35″ furnace include stress relieving of molybdenum (moly) weldments, high temperature sintering of moly and ruthenium, and TiC or SiC coatings of graphite parts.
Bruce Craven, Solar Vice President, directly oversees high temperature furnace operations. Â Although Solar has 20 vacuum furnaces, Craven states, “the addition of a higher temperature furnace broadens the processing applications of vacuum furnace technology. Specifically, precise temperature parameters and specified furnace environments at these high temperatures provide new processing possibilities for exotic metal parts.”
Furnace capabilities include vacuum levels of 1×10-5 torr. Â Partial pressure operating atmospheres are available in N2, Argon and H2 from 0.5 torr to 50 torr in flowing gas. Â Furnace temperature control is via type C thermocouples and a Honeywell Model 550 microprocessor based progammer/controller.
Solar will assist customers with metallurgical consultation and prototype development for high temperature applications. Â Further information is available at Solar’s web site, www.solaratm.com. Contact Ken Bauhof, Sales Engineer, or Bruce Craven at 800 347-3236.
