*Carbon and silicon targets are specified for each bar size in order to maintain mechanical properties. Magnesium is added as an inoculant to produce nodular graphite. Small amounts of alloying elements are used to stabilize the pearlitic structure.
Brinell Hardness
Hardness properties for various diameters are shown in the table. Hardness properties listed are minimum and maximum across the bar. For rectangles, squares and shapes, the hardness properties will depend on minimum and maximum section thickness and will be supplied on request.
25 - 38
38 - 76
76 - 508
Tensile strength is determined from a longitudinal test specimen taken from mid-radius of the as-cast bar. In bars under 1.5" diameter, elongation will be 4% minimum.
Tensile Strength psi (min) 80,000
Yield Strength psi (min) 55,000
Elongation (min) 6%
