Salt Bath Nitriding (SBN)

SBN is a multi step process that provides a very uniform consistent nitride layer on your components

The ovens at Metcor can handle parts up to 45" in diameter and 52" long with different finishes available. SBN QPQ is a thermo-chemical processes intended for the case hardening of iron based metals. These processes are categorized as molten salt bath ferritic nitro-carburizing.

  • SBN-Q
    • Improved Wear Resistance
    • Improved Running Properties
    • Increased Fatigue and Rolling Fatigue Strengths
    • Heat Resistance
    • Black Color
  • SBN-QP
    • lncludes the properties of Q
    • Lower coefficient of Friction
    • Decreased surface roughness
    • lncludes the properties of Q and QP
    • Low Light Reflection
    • Further Decreased Coefficient of Friction
    • Enhanced Corrosion Resistance (Not suitable for stainless)
