1.7225 / AISI 4140 is a chromium-molybdenum alloy steel grade with a slightly higher carbon content than 4130, delivering greater tensile strength and a strong response to heat treatment. Supplied by Dongguan Songshun Mould Steel Co., Ltd. from Dongguan, China, this flat bar stock is offered in hot-rolled or forged delivery condition with annealed or quenched-and-tempered heat treatment options. Surface finishes available include black, peeled, polished, and machined, allowing buyers to match the bar to downstream processing requirements.
Typical applications for 4140 flat bar span high-stress mechanical components such as crankshafts, gears, pump shafts, connection rods, conveyor pins, stem assemblies, and tool holders.
