Product Description

Bright Annealed Alloy Case Hardening Steels 1.5714 16NiCr4 4320 EN351 635M15 637M17

1: 16NiCr4 steel introduction

    16NiCr4 Alloy steel is a low carbon case hardening steel which has at least 0.6Cr%,0.8%Ni as strengthening elements. It has a low-medium hardenability with good core resistance up to a thickness of about 50 mm, and had good machinability in the annealed condition.16NiCr4 is generally supplied in the annealed condition with Max hardness 217HB.

6. Heat Treatment

Forging
    16NiCr4 Alloy steel forging temperature:900 - 1150°C, cooled as slowly as possible in still air or in the sand after forged.
Heat Treatment
    Normalizing: 870 - 890°C, Cooling in air
    Soft Annealing:680 - 720°C, Cooling in the furnace
    Carburizing:880-980°C
    Core-hardening:850-890°C,oil-polymer salt bath
    Case-hardening:780-820°C,oil-polymer salt bath
    Carbonitriding:860-930°C/Gas
    Tempering:150-200°C
Surface Hardness
    Treated to improve wearability(+S): Max 255HB
    Soft annealed(+A): Max 217HB
    Treated to hardness range(+TH):166-217HB
    Treated to ferrite-pearlite structure and hardness range(+FP):156-207HB

 

7: Delivery condition
    For hot forged rolled bar, usually the delivery condition is hot forged or rolled, annealed/QT, rough turned/Black surface.
    For hot forged or hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
    For hot forged plate, usually the delivery condition is hot forged, annealed/QT, milled surface/Black surface.
    For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
