e.t.d. 150® As Drawn

HOT ROLLED & COLD FINISHED

"e.t.d." 150® is a high strength alloy steel with improved machinability. LaSalle Steel manufactures "e.t.d." 150® from medium carbon 4100 series alloy steel modified with one machinability additive such as selenium, sulfur, or tellurium. The high strength is developed by elevated temperature drawing below the critical temperature range. Mechanical properties are exceptionally uniform throughout the cross section of each bar. "e.t.d." 150® is often used to replace material being heat treated to the 32/38 HRC range. It can be roll threaded, knurled or plated and is suitable for induction hardening. Welding is generally not recommended.
