This specification covers hot-finished or cold-finished plate, sheet, and strip in the more commonly used types of stainless free machining steels designed especially for optimum machinability and for general corrosion and high temperature service. Stainless and heat-resisting plate, sheet, and strip, are covered in separated specifications. The steel shall be made by one or more of the following processes: electric-arc, electric-induction, or other suitable commercial processes. The chemical composition shall conform to the requirements specified. Hardness test shall conform to the hardness requirements specified.

1.1 This specification covers hot-finished or cold-finished plate, sheet, and strip in the more commonly used types of stainless free machining steels designed especially for optimum machinability and for general corrosion and high temperature service. Stainless and heat-resisting plate, sheet, and strip, other than free-machining types, are covered in separate specifications.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
