Ferrium® C61 is a superior alternative to conventional gear materials such as AISI 9310 and EN36C for new smaller, lighter, high-temperature resistant component designs, or to upgrade the alloy in an existing component where a re-design is not feasible.

Ferrium C61 was designed to provide carburized surface properties (60-62 HRC) similar to conventional gear steels such as AISI 9310 and EN36C with the added benefit of an ultrahigh-strength core along with excellent fracture toughness. A typical hardness profile of carburized Ferrium C61 is shown to the left. Advantages

ble alloys. The benefits of using Pyrowear 61 include light weighting of components and increasing po. tempering. The typical hardness after tempering is . ecommended. This should be performed with minimal delay after completion of.

Ferrium® C61 has surface-wear properties similar to those found in popular commercial alloys but provides an ultra-high-strength, high-toughness, high-temperature-resistant core. Other features include superior axial and STBF fatigue resistance. Ferrium® C61 is particularly advantageous to reduce the size and weight of integrally geared ...

technology to design, develop and insert four new Ferrium® high-performance gear and structural steels (Ferrium C61™, Ferrium C64™, Ferrium M54™, and Ferrium S53®) that are now commercially available and can significantly reduce rotorcraft weight and manufacturing costs while increasing operational robustness

Ferrium® C61™ was designed to provide carburized surface properties similar to conventional gear steels such as AISI 9310 and EN36C with the added benefit of an ultra high-strength core along with excellent fracture toughness.

2012年1月7日 · A new class of gear steels, Ferrium® C61 and C64, were specifically designed and developed to maximize the benefit of vacuum carburization processes. Ferrium C61 and C64 are highly hardenable, secondary hardening martensitic steels.

2014年2月12日 · Ferrium C61 (AMS 6517) exhibits both excellent surface fatigue and core properties (225 ksi yield strength, 240 ksi ultimate tensile strength, 130 ksi•?in fracture toughness), and is a good candidate for integral gear/shaft applications where maximum torque transfer with minimum weight is tantamount.

2022年2月28日 · He was referring to Ferrium ® C61 ™ steel (AMS 6517), QuesTek’s computationally-designed alloy and a performance upgrade vs. previously used high performance gear steels such as AISI 9310 steel. Its key features …

2011年11月1日 · Single tooth bending fatigue (STBF) test data of UHS Ferrium C61 and C64 alloys are presented in comparison with historical test data of conventional gear steels (9310 and Pyrowear 53) with comparable statistical analysis methods. Pitting and scoring tests of C61 and C64 are works in progress.
