Clean Technology Focused on Making Gears Last Longer, Perform Better

TimkenSteel’s Endurance family of steels includes three new, patent-pending, ultra-high-strength, high-toughness grades; offers gear manufacturers the ability to achieve lighter weight, longer life and/or more power.

For 100 years, TimkenSteel (NYSE: TMST, www.timkensteel.com) has created some of the cleanest and best-performing special bar quality (SBQ) steel in the industry. Today, the company offers customers more than 500 grades.



This family of Endurance steels, comprised of both TimkenSteel’s existing high-strength and/or high-toughness grades as well as three new, patent-pending, ultra-high-strength, high-toughness steels, results from close collaboration with a broad range of industrial, oil and gas and automotive customers to achieve enhanced performance in extremely demanding applications.

“We’ve always been a leader in developing high-performance steels, and now we’re making our offering even better,” said Ray Fryan, TimkenSteel’s vice president of technology and quality. “Endurance steels combine higher levels of strength and toughness, driven by an application’s unique requirements. For our customers and, in turn, their customers, this can translate to increased power transmission, lighter weight, and/or extended product life and reduced component failure. Better yet, using Endurance steels, customers don’t have to redesign their components or processes to reap the benefits.”

Endurance grades are suited for demanding applications in oil and gas, mining, military, marine, construction and more. In fact, a primary benefit of the Endurance line is that it provides multiple material options that can satisfy a range of performance objectives.

In highly engineered components like gears, these grades’ higher levels of strength and toughness offer gear designers/manufacturers the ability to create improved gears that can achieve significant savings and performance advantages over those produced from more traditional steel grades. Additional benefits may include reduced downtime and lower warranty costs.

“These steels serve demanding, energy-intensive environments where components are handling very high loads and also moving at very high speeds,” Fryan said. “They offer an incredible amount of strength and toughness in a small envelope.

“Our technology team is constantly working to push the bounds of what’s possible to meet not only today’s needs, but what our customers are looking for five, 10 and even 100 years from now,” Fryan said.
