Round steel bars maintain toughness and hardness without brittleness
Astralloy-V® round wear bars are air quenched/hardened, creating uniform hardness throughout the entire thickness of the bar, providing excellent wear resistance and slidability. Astralloy-V® round bars maintain both their toughness and hardness – without brittleness – down to -75°F (-60°C) and can withstand temperatures up to 1100°F (593°C).
Astralloy-V® round bars’ oxide (mill) surface quickly wears off, exposing a slick, durable surface. Impact and sliding action increase the bars’ hardenability up to 550 BHN without the bars deforming or becoming brittle. Astralloy-V® abrasion-resistant round bars can be hot worked and allowed to air cool without loss of hardness or toughness – and without warping.
Typical applications for our hot-rolled Astralloy-V® round bars including downhole drilling tools, high duty gears, pinions, areo-engine connection rods, differential shafts and other transmission components, airframe forgings, heavy roller bearings, breech mechanism, and small arms components.
