ETD 150 Alloy Round Bar Stock

Our ETD 150 Alloy round bar stock is the perfect metal for forging things that carbon steel cannot provide.

Sturdy ETD 150 Alloy Round Bar Stock Fit for Machining

An ETD 150 Alloy bar stock is a modified alloy created by means of drawing out an elevated temperature with a heavy draft. Problems concerning warpage and distortion, and the residual cold stresses when cold working with the controlled-die practice, are reduced. in order to achieve good hardness and strength with a minimum Rockwell of C Hardness 32. ETD 15 Alloy round bar stock has tensile and yields strength properties. Wielding this alloy may prove to be quite difficult as sections may need to be preheated first and stress-relieved afterward. This Alloy is a worthwhile investment as it eliminates the need for heat-treating and any possible secondary operations such as cleaning, straightening, and grinding. This steel is commonly used for shafts, axles, gear, pinions, and so much more. Application-wise, it is a great metal that can be used in fine machine sections as it doesn’t easily warp during final hardening.
