40CrMnMoS8-6 Steel: A Technical Guide to Composition, Properties, and Applications
What Is 40CrMnMoS8-6 Steel?
40CrMnMoS8-6 steel is a high-performance, low-alloy case hardening steel engineered for demanding industrial applications. Standardized under EN 10084, this grade is specifically designed to provide a unique combination of a hard, wear-resistant surface and a tough, ductile core after heat treatment. Industries value this material for its exceptional machinability, which is enhanced by a controlled sulfur content, making it ideal for manufacturing complex components like gears, shafts, and other high-stress mechanical parts.
The performance of the 40CrMnMoS8-6 material stems from its carefully balanced chemical composition. The inclusion of chromium, manganese, and molybdenum provides excellent hardenability and core strength, while the elevated sulfur content significantly improves chip-breaking characteristics during machining. This guide provides a detailed technical overview for engineers, procurement managers, and industrial buyers, covering everything from the steel's chemical makeup to its performance in various applications.
