SPECIFICATIONS: GRADE ETD 150®
Castle Metals stocks ETD 150 bars through our global distribution network. Our service centers are located in the U.S., Canada, Mexico, U.K, France, Singapore, and Shanghai. Customers calling us for ETD 150 a lot of times are struggling with finding commercially available products to meet their specifications. Castle Metals hears these issues often and has resources for thermal and mechanical treatment to deliver customer specific properties.
Alloy ETD 150® is a variation of AISI Alloy 4142 with machining additives and is a registered trademark of Niagara LaSalle Corporation. E.T.D. stands for Elevated Temperature Drawing process. It is drawn at an elevated temperature with a heavy draft to achieve good hardness and strength with a minimum Rockwell ¿C¿ 32. This severe draw eliminates heat treating and secondary operations making ETD 150® a relatively low-cost choice.
