41L40/41L42 Alloy Round Bar Stock

Our 41L40/41L42 alloy round bar stock is the perfect metal for forging things that carbon steel cannot provide.

Hardy and Wear Resistant 41L40/41L42 Alloy Bar Stock

41L40/41L42 Alloy bar stock are grades that are capable of strength and wear resistance as this is a free-machining version of Chromium-Molybdenum which in turn gives it excellent toughness and ductility allowing it the ability to resist stress and creep at prolonged high temperatures. The addition of a small amount of lead to 41L40/41L42 Alloy bar stock chemistry and its cold drawing will increase its average machinability rating to 86%. The common applications of 41L40/41L42 Alloy round bar stock include drill collars, kelly bars, bolts, couplings, subs, rotary table shafting, oil well tool joints, reamer bodies, sprockets, trailer axles, spindles, chain links, zinc die casting dies and much more but this does not mean that you should be using this in applications that are over 400deg F. elevated temperatures as it may cause lower ductility in leaded grades.
