Latest Patents

Kazuhiko Ohno holds a patent for a steel material with excellent rolling fatigue life and the method of producing the same. This steel composition includes 0.7 to 1.1% carbon, 0.2 to 2.0% silicon, 0.4 to 2.5% manganese, 1.6 to 4.0% chromium, and 0.1% or more but less than 0.5% molybdenum, along with 0.010 to 0.050% aluminum, with the balance being iron and inevitable impurities. The steel is treated through quenching and tempering, resulting in residual cementite grain sizes ranging from 0.05 to 1.5 micrometers and prior-austenite grain sizes of 30 micrometers or smaller. This innovative steel is particularly beneficial when used in bearing applications, as it extends bearing life even under severe service conditions.
