ABEX PARABOLOY is a high-chromium cast iron produced under strictly controlled foundry conditions and heat treated to furnish two grades: PAB and PAC. PAB provides excellent wearlife in heavy-section castings for mill liners and selected crusher parts. PAC provides excellent service in applications requiring greater resistance to shock and impact. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and compressive strength as well as fracture toughness. It also includes information on wear resistance as well as heat treating, machining, and joining. Filing Code: CI-49. Producer or source: Abex Corporation, Armsco Division.
