NITRALLOY 135 MODIFIED is a special alloy steel which can be nitrided, that is, surface hardened without final quenching by the action of ammonia gas at relatively low temperatures. (Also known as Nitralloy Type G Modified). This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-24. Producer or source: Alloy steel mills and foundries.
