Deep cryogenic treatment of broaches at temperature levels below -300°F have shown significant improvement in extending broach life four to five times. Cryogenic treatment of these broaches has allowed the broaches to produce between four and five times the amount of parts. Broaches saw a minimum of 300%+ increase in lifetime after cryogenic treatment.
|APPLICATIONS||AVG. LIFE BEFORE TREATMENT||AVG. LIFE AFTER TREATMENT||PERCENT IMPROVEMENT|
|C1029 Steel Torque Tube Yoke||1810 PARTS||8620 PARTS||376%|
|Forged Connecting Rods||1500 PARTS||8600 PARTS||573%|
