ETD-150 steel is an elevated temperature drawn grade. Machine shops in the Chicago area use it for precision shafting because the bar arrives with consistent mechanical properties from end to end. That consistency means your turning center works with material that behaves the same way across the full bar length, reducing setup variability and saving time per piece.
We carry ETD-150 at O’Hare Precision Metals in Arlington Heights. If you’re evaluating it for a shafting application, this guide covers what the grade is, how we process it, and which companion services apply to your order. Every detail here maps directly to what we do in our facility.
ETD-150 Steel for Precision Shafting: A Complete Buyer’s Guide
ETD-150 falls within our alloy steel round bar category alongside grades such as 4130, 4140, and 4340. Each of those grades serves shafting and structural work differently. ETD-150 earns its place because the elevated temperature drawing process gives you a bar that machines predictably without excessive cleanup before your part reaches its final dimension.
Shops running automotive, construction, oil and gas, and general manufacturing shafting components deal with the same challenge. They need a round bar that holds dimensions through secondary machining. ETD-150 addresses that need directly, and pairing it with our in-house precision grinding takes the bar even further before it reaches your machine.
What Elevated Temperature Drawing Means for Your Shaft
The name tells you the process. Drawing the bar at elevated temperature produces uniform mechanical properties along the full bar length. For a shaft going into a bearing bore or a seal assembly, that uniformity means your diameter stays consistent from one end to the other without surprises during machining.
This is the reason production shops in the Chicago area reach for ETD-150 when volume shafting work is on the schedule. A bar that arrives mechanically uniform lets your tooling work efficiently. You spend less time correcting variation and more time producing good parts at the dimensions you need.
Turning, Burnishing, and Cutting for Shafting Orders
Our turning service reduces workpiece diameter to a specified dimension and generates a smooth cylindrical surface on the metals we process. O’Hare Precision Metals handles short and long pieces across different diameters, and we use center and face drilling to support longer bars through the operation. For shafts with shoulder features or stepped dimensions, turning addresses those details after centerless grinding brings the bar to its base dimension.
Burnishing is worth adding for shafts that run under cyclic load or contact seals. We perform roller burnishing on cylindrical workpieces, including shaft outside diameters, fillets, and sealing surfaces. The process creates compressive residual stress in the surface, which resists fatigue failure and closes surface porosity. We also cold saw cut bars to your custom length using automated CNC saws that handle up to 7 inches in diameter, producing cleaner ends than friction or bandsaw methods.
Chamfering, Packaging, and Quality at Every Step
We chamfer ETD-150 bars in-house using both CNC and manual equipment. Chamfered ends make assembly easier and prepare bar ends for welding when your design calls for it. Finished bars ship in individually wrapped tubes and collars, custom wood boxes, or paper wrap bundles. We accommodate custom packaging per customer preference.
We are ISO 9001:2015 certified, and quality control runs through every phase of our operation. That means the bar you receive has been inspected at each process step, not only at the end. For shafting that goes into critical assemblies across automotive, construction, and oil and gas applications, that inspection cadence matters before the material reaches your machine.
Other Alloy Grades O’Hare Precision Metals Carries for Shafting Work
ETD-150 is a strong fit for many shafting applications, but it’s not your only option in our inventory. If your design requires higher toughness under impact, 4340 is a nickel-chromium-molybdenum alloy used in aircraft and automotive crankshafts. For wear resistance under high stress, 4140 is a proven choice. For forged shafts and spindles, 4135 works well as a low-alloy option.
We also carry 9310 for heavy-duty gear shafts and crankshafts, and 8740 for high-strength fastening applications. DOM steel tubing is available in the alloy category as well. If you’re not certain which grade fits your load requirements, we’re glad to work through the options with you before you place an order.
