The carbon percentage present is 3-4% and percentage of silicon is 1.8-2.8%.Tiny amounts of 0.02 to 0.1% magnesium, and only 0.02 to 0.04% cerium added to these alloys slow the growth of graphite precipitates by bonding to the edges of the graphite planes. Along with careful control of other elements and timing, this allows the carbon to ...
ρ m = density of the metal (in [kg·m −3]), c m = specific heat of the metal (in [J·kg −1 ·K −1 ] ). It is most useful in determining if a riser will solidify before the casting, because if the riser solidifies first then defects like shrinkage or porosity can form.
Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. [ 1 ] It is the most common cast iron and the most widely used cast material based on weight.
The higher grades have more cobalt and titanium in the alloy; the compositions below are taken from table 1 of MIL-S-46850D. As of July 1, 2024, that standard was cancelled by the U.S. Military and replaced with a number of SAE AMS specifications, which now govern each grade in a separate specification, as enumerated below [ 11 ] .
Steel casting is a specialized form of casting involving various types of steel cast to either final/net or near-net shape. Steel castings are used when iron castings cannot deliver enough strength or shock resistance. [1]
