Abstract
The invention discloses a corrosion-resistant alloy cast iron material for a diesel engine cylinder and a preparing method thereof. The gray cast iron material for the diesel engine cylinder comprises the following components in a percent by mass: 2.8-3.2% of C, 2.2-2.6% of Si, 4.4-4.8% of Ni, 1.9-2.3% of Cr, 3.5-4.0% of Cu, 0.2-0.4% of Mn, 0.3-0.6% of In, 0.2-0.4% of Ge, 0.05-0.1% of La, 0.04-0.08% of Pm, 0.03-0.06% of Gd, 0.04-0.07% of P, 0.02-0.04% of S and the balance of Fe. The gray cast iron material prepared by the preparing method has the characteristics of being outstanding in corrosion resistance, high in strength, great in tenacity, great in thermal resistance and the like.
