1144 Stressproof™ CF Round Bar

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. Meets ASTM A311, Class B. Stressproof™ is a registered trademark of the LaSalle Steel Co.
