    0.732" Steel Plate, Disk, 9.50" Diameter, 4140 Steel, Round, Circle
    4140 Hot Rolled Annealed
    OSI stocks 4140 HR Annealed -a steel in the family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, CrMo, CRMO, CR-MOLY, and similar). They have an excellent strength to weight ratio and are considerably stronger and harder than standard 1020 steel, but are not easily welded (need pre and post weld thermal treatment to avoid cold cracking). While these grades of steel do contain chromium, it is not in great enough quantities to provide the corrosion resistance found in stainless steel.
    Properties
    4140 is typically bought to meet chemistry requirements rather than physical requirements. For that reason, physical properties are generally not provided unless requested prior to production. Any material can be sent to a third party after production to be tested for physical properties.
    Typical Uses
    Typical uses for 4140 include:
    Jigs
    Fixtures
    Drill Collars
    bolts
    Stubs
    Couplings
