1144 Stressproof is a carbon-manganese free machining grade, severely cold worked to produce high tensile properties. It is a specially treated grade to relieve the stresses set up by the cold working, and therefore reducing warpage tendencies after machining, which is common in ordinary cold drawn bars.
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.16 feb 2005
High carbon steels are very hard, which makes them good at resisting abrasion and retaining shape. They can withstand significant force before deforming. Unfortunately, hard metals are also brittle: when placed under extreme tensile stress, high carbon steels are more likely to crack than bend.
