  • Brief Introduction

    Properties

    The shell is a high carbon alloy steel containing Cr, Mo, W, V and Nb. The microstructure consists of complex carbides embedded in a tempered martensitic matrix. Control of the carbon and a complex heat treatment allows the optimization of wear-resistance, thermal fatigue resistance and oxide film formation, whilst maintaining low residual stress values.

    Mechanical Properties Centrifugal
    Hardness of shell HSD75-85
    Hardness of neck HSD35-48
    Tensile Strength of Core ≥450Mpa
