EN 36

Nickel-Chromium Steel For High-Performance Components

EN 36 is a nickel-chromium alloy steel commonly used for components that require a combination of surface hardness, toughness, and wear resistance after suitable case-hardening treatment.

Available Forms: Round Bars | Flats | Blocks | Custom Sizes

Key Properties
Built For Surface Hardness. Designed For Core Toughness.

  • High Surface Hardness
    Suitable for Applications Requiring a Hardened, Wear-Resistant Surface.Tough Core
    The Alloy Composition Supports A Tough Core Beneath The Hardened Case.    Wear Resistance
    Suitable For Components Exposed To Repeated Contact And Mechanical Wear.    High Load Performance
    Designed For Demanding Mechanical And Power-transmission Applications.    Case Hardening
    Can Be Carburized And Heat Treated To Develop The Required Surface Properties.    Engineering Versatility
    Suitable For Gears, Shafts, pins, and other precision mechanical components.
