ASTM A895-89(2000)

Standard Specification for Free-Machining Stainless Steel Plate, Sheet, and Strip

SCOPE
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 the standard.
