Machinability and other Processes

A special treatment has been applied to alleviate metal tensions caused by the manufacturing process, making it highly stable and long-lasting. 1144 is a machining grade free of carbon and manganese and has been severely cold worked to produce high tensile properties. It is a specially treated grade that is designed to relieve the stresses created by cold working, thereby reducing warpage tendencies after machining, which are common in ordinary cold-drawn bars.


There is no denying that 1144 Carbon has a ton of uses. Nuts, bolts, gears, screws, pumps, sleeves, and motors are its typical industrial applications.
