A brazing and heat treating services supplier based in Northern California has announced the expansion of process services to their heat treating line. ThermoFusion now offers marquenching and austempering, in addition to their annealing, hardening, vacuum, and hydrogen services, for clients in the aerospace, automotive, medical, energy and general manufacturing industries.
Marquenching and austempering use a less aggressive quenchant, reducing the cooling rate slightly, and reducing distortion caused by rapid temperature change (thermal shock). In high carbon material, these alternative processes allow for the formation of bainite instead of martensite, which allows spring steels to remain “springy” as they get hard.
