Jalloy-AR is the trade name of a group of constructional steels which boost working limits for abrasive resistance at high yield-strength levels. This series is produced in two sets of hardness values, namely, Jalloy-AR-360 with a hardness rating of 340-380 Brinell and Jalloy-AR-400 with a minimum hardness rating of 400 Brinell. 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-153. Producer or source: Jones & Laughlin Steel Corporation.
