Cold Rolled 1144 Steel Round Bar

Cold Rolled 1144 Steel Round Bar

Product Description:

Stressproof is a trade name of Niagara LaSalle for a modified SAE 1144 steel . The trade name has since taken on a life of its own and 1144 is commonly referred to as “stressproof”. This material is a higher-strength alloy than 1018 or A36, with improved ductility. The chief feature of 1144 steel is that it has very low distortion or warpage after machining due to a combination of its chemistry, method of manufacture, and heat treatment. 1144 is relatively easy to machine, with a machinability rating of 83% of AISI 1212 steel.
