Kennametal introduces KCS10B for superalloy applications

KCS10B is available in several popular turning insert shapes, sizes, and geometries.

Kennametal has introduced its latest turning-grade KCS10B, for nickel, cobalt and iron-based superalloys used in aerospace and other high-temperature applications.

Beating wear
Metals such as Inconel 718 and Stellite 31 are notorious for causing rapid wear and unpredictable tool life, KCS10B is proven to reduce DOC notching and extend tool life from 3 minutes to upwards of 5 minutes in roughing operations. Tool life in finishing operations fares even better, with visible cratering and subsequent tool failure often delayed by a factor of two or three compared to competitive brands.

Depth-of-cut notching and crater wear are far more manageable thanks to the super smooth coating and special edge-prep of inserts coated with KCS10B.

“Aside from a smoother surface, the new coating process also allows us to create a much sharper edge,” said Keilmann. “Our advanced honing and edge-preparation process reduces the friction that leads to heat, which further improves tool life.”

Positive and negative rake inserts are available, as well as various chip formers, edge preparations, and geometries, making KCS10B the ideal solution when turning iron-based (S1), cobalt-based (S2), or nickel-based (S3) alloys.

“It also means less built-up edge, another common failure mode in super alloy materials,” he added. “When coupled with the excellent dimensional accuracy that Kennametal turning inserts are known for, shops can now expect the increased performance, stability, and predictability needed to be successful with these challenging alloys.”
