HTN is a ductile iron which is heat treatable for producing a wide range of properties. Austempering or quench and temper treatments are applicable. HTN has high hardenability and excellent wear resistance. Its as-cast microstructure is predominantly pearlitic with less than 5% free carbides, well dispersed. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on heat treating and machining. Filing Code: CI-59. Producer or source: Federal Bronze Products Inc..
