Title:
CAST IRON HAVING SCUFFING RESISTANCE AND WEAR RESISTANCE
Document Type and Number:
Japanese Patent JP3218625
Kind Code:
B2
Abstract:
PURPOSE: To provide a thin CV graphite cast iron excellent in scuffing resistance and wear resistance as well as in toughness.
CONSTITUTION: This cast iron has a composition consisting of, by weight ratio, 3.2-4.0% C, 1.5-2.8% Si, 0.3-0.7% Mn, ≤0.05% P, ≤0.015% S, 0.05-0.5% Cr, 0.05-0.15% V, 0.7-1.5% Ni, 0.5-3.0% Cu, and the balance essentially Fe and also has a structure where compacted.vermicular graphite exists in a tempered martensite or bainite matrix. Because the precipitated compacted. vermicular graphite is fine, this cast iron has superior mechanical strength, toughness, scuffing resistance, wear resistance, etc., and can be suitably used as a stock for thin sliding parts, such as piston ring.
