What is ASTM A311?

ASTM A311 / A311M – 04(2020) Standard Specification for Cold-Drawn, Stress-Relieved Carbon Steel Bars Subject to Mechanical Property Requirements.

What is the difference between 1144 and StressProof?

1144 CD is cold drawn. The cold drawing will tend to offset the deleterious effects of any decarb that might have been present in the original hot rolled bar.So, you can buy the bar size you need. Big difference I see is that StressProof comes with guarranteed min properties, whereas 1144 CD doesn’t.

What is fatigue proof steel?

FATIGUE-PROOF is a medium-carbon free-machining steel with higher mechanical properties than its companion product, STRESSPROOF. These properties are produced by a process of drawing steel at elevated temperatures, developed and patented by LaSalle Steel Co.

Can you weld stress proof steel?

Stressproof is produced from AISI 1144 carbon steel. Because Stressproof is a resulfurized steel, welding is not recommended.

What ETD 150?

E.T.D. 150® stands for Elevated Temperature Drawing process. This eliminates heat treating and secondary operations such as straightening, finish grinding, cleaning and inspections. This eliminates heat treating and secondary operations such as straightening, finish grinding, and cleaning.
