6、e requirement for determining yield strength for wire under 0.125 inch (3.18mm) diameter (3.3.1) and results from a Five Year Review and update of this specification. 1. SCOPE 1.1 Form This specification covers a corrosion resistant steel in the form of bars and wire 0.75 inch (19 mm) and under in n
7、ominal diameter or distance between parallel sides. 1.2 Application These products have been used typically for small parts, such as bolts, screws, and clevis pins, requiring corrosion resistance up to 700 F (371 C) and which may be fabricated by heading or by machining from bars or wire and roll th
8、reading, but usage is not limited to such applications. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a sp
9、ecific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply.
