UNS H41370 is a low-alloy steel containing nominally 0.95% Cr and 0.20% Mo. It has good resistance to abrasion, fatigue, and impact. It can be nitrided successfully for maximum resistance to abrasion and wear. It is suitable for severe service characterized by high stresses and impact loading in both small and large sections. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-427. Producer or source: Alloy steel mills and foundries.
