6、ve Year Review and update of this specification. 1. SCOPE 1.1 FormThis specification covers a corrosion and heat resistant steel in the form of bars, wire, forgings, mechanical tubing, flash welded rings, and stock for forging or flash welded rings. 1.2 ApplicationThese products have been used typic
7、ally for parts requiring good corrosion resistance and which will be subjected to elevated temperatures during fabrication or in service and for parts requiring oxidation resistance up to 2000 F (1093 C) but useful at the higher temperatures only when stresses are low, but usage is not limited to su
8、ch applications. 1.2.1 Strength at elevated temperatures is similar to that of the 18-8 type steels. The specified silicon content improves oxidation resistance with some sacrifice of weldability and ductility. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the
9、 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 specific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last publ
10、ished issue of that document shall apply. 2.1 SAE Publications Available from SAE International, 400 Commonwealth Drive, Warrendale, PA 15096-0001, Tel: 877-606-7323 (inside USA and Canada) or 724-776-4970 (outside USA), www.sae.org.AMS2241 Tolerances, Corrosion and Heat-Resistant Steel, Iron Alloy,

37、n AMS are clarified in ARP1917 and as follows: 8.3.1 The term “mechanical tubing“ as used in AMS means a heavy-walled cylindrical tubing, intended primarily for the machining of circular rings, flanges, shafts, etc, having a wall thickness which is a substantial proportion of the outer diameters. Su
38、ch tubing is not normally used for the transmission of fluids and parts made from it are usually machined all over. This product is sometimes known as “hollow bar“.
