Sand Casting Process Grey Cast Iron

Grey Cast Iron Casting Product Introduction

Gray cast iron refers to the cast iron with flake graphite, because the fracture is dark gray when broken, so it is called gray cast iron. The main components are iron, carbon, silicon, manganese, sulfur, phosphorus, and it is the most widely used cast iron.

Product Feature

Different from other castings, the basic characteristics of ,grey iron sand casting are: high clay content, low moisture, and low coal powder addition. The mechanical properties of gray iron castings are related to the microstructure of the matrix and the morphology of graphite. The graphite in the gray iron castings seriously splits the matrix, and it is easy to cause stress concentration at the sharp corners of the graphite, so that the tensile strength, plasticity and toughness of the gray iron castings are much lower than those of steel, but the compressive strength is comparable to that of steel.
