Cryogenic Thermal Treatment

 

Find Suppliers by Category

Heat treating services perform thermal treatments to modify the properties of metals and metal alloys. Common processes include annealing, austempering, case hardening, conventional hardening, homogenizing, hot isostatic pressing (HIP), martempering, normalizing, precipitation hardening, shot peening, solution treating, spheroidizing, stabilizing, and stress relieving.

    The environmental challenges of space-related applications are immense, and include vacuum (10-8 to 10-12 torr), deep space cryogenic (20 Kelvin), thermal shock (sun at +200°C to shade at -200°C in one to two seconds), launch vibration, ionized particles and radiation. In addition

They also work at cryogenic temperatures down to 450 F. Graphite alone lacks the durability for bearings so it is often
