This specification covers austenitic, austenitic-ferritic, ferritic, and martensitic stainless steel forgings for general use, and for low- or high-temperature service. If it must be welded, preheat to F C and post weld treat at F C for 6 hours followed by a slow furnace cooling to avoid cracking. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
The steel shall conform to the specified chemical composition and room temperature mechanical requirements. The number of and procedure for tension test for forgings depending on their weight are presented.
Maximum obtainable hardness is RC This a43 is also available to be included in Standards Subscriptions. The tension test specimens shall be taken from the test prolongations or from the forgings. If the document is revised or amended, you will be notified by email.
