6、nd is 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, wire, forgings, mechanical tubing, flash welded rings 8.0 inches (200 mm) and under in least nominal cross-sectional dimension, and stock of any siz
7、e for forging or flash welded rings (see 8.6). 1.2 Application These products have been used typically for parts requiring corrosion resistance approximating that of steels of the 18-8 types and high strength exceeding that of the 12 Cr martensitic types up to 700 F (370 C), but usage is not limited
8、 to such applications. 1.3 This steel can be used in the solution heat treated condition and is capable of being precipitation heat treated to tensile strengths as high as 180 ksi (1240 MPa), minimum. 1.4 Although this steel is relatively immune to stress-corrosion cracking, reference should be made
9、 to ARP1110 for recommended practices to minimize such conditions. 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
10、unless a specific 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.
