Product Description

Description of Valve Guide for MAN 32/40
1. Material: GGV HB200
A). Mechanical properties:
Tensile strength: 250MPa min. Hardness: HB220-260
B). Matrix: Perlite, ferrite 10% max.; Graphite: Preferably lamellar and uniformly distributed; Phosphide eutectic: Preferably continuous network.
2. Guide bore to be gun drilled and plateau honed for excellent bore diameter and straightness and achieving cross hatch pattern for better running-in;
3. Fitting diameter to be ground, and achieving max. 0.0008' concentricity between guide bore and fitting dia.
