Clean Engineered Steels - Progress at the End of the Twentieth Century

Source

The Timken Company, a manufacturer of alloy steel and bearings, has developed a 15 MHz ultrasonic inspection method that correlates steel cleanness to bearing fatigue performance. It is used to qualify worldwide bearing steel suppliers for cleanness requirements, to monitor their compliance and qualify process changes. This method has permitted the appropriate steel cleanness to be selected for bearing applications. Through Continuous Improvement (CI) methodology, steelmaking productivity advancements have occurred along with advancement in steel cleanness. These efforts have led to 4 orders of magnitude steel cleanness improvement, and nearly 20 times bearing performance improvement over the past 15 years.
