ETD 150® Alloy Steel Round

etd150_alloy_steel_round_bar

ETD 150 is similar in composition to 4140 alloy. It is produced by the Elevated Temperature Drawing process patented by the La Salle Steel Co. This process results in a bar that is stress-free and a minimum of 32 Rockwell C hardness, eleminating the need for further heat treating methods. When higher hardness is desired, a level of 57-60 Rockwell C is attainable by quenching and tempering. Along with their high strength, these bars have excellent machining characteristics. Uses include: axles, shafts, gears, pinions, fasteners.

  • Finish: Cold Finished
  • Typical Tolerances: +0/-.008"
  • Applications: pinions, gears, shafts, axles, bolts, pins
