Grade SB24M13B is a boron steel for general purposes without any specified mechanical properties.Its closest equivalent is found in the standard number 22MnB5.This grade is suitable to serve as chains (side-links) in materials handling equipment of various kinds that are exposed to heavy wear and varying stresses (bending, tensile, fatigue). This grade also works well as wear parts in snow ploughs/graders and in the machinery of agriculture machines because of its good hardness and toughness in heat-treated condition in dimensions up to Ø 40 mm or equivalent thickness.
