SAE AMS 5398F:2000 pdf download Steel, Corrosion-Resistant, Sand and Centrifugal Castings 16Cr – 4.1Ni – 0.22Cb (Nb) – 2.8Cu Solution Heat Treated
1. SCOPE
1.1 Form
This specification covers a corrosion-resistant steel in the form of sand or centrifugal castings.
1.2 Application
These castings have been used typically for parts requiring corrosion resistance and strength up to 600 °F (316 °C), but usage is not limited to such applications. Certain processing procedures and service conditions may cause these products to become subject to stress-corrosion cracking; ARP1110 recommends 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 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.

3. TECHNICAL REQUIREMENTS
3.1 Composition
Castings shall conform to the percentages by weight shown in Table 1, determined in accordance with ASTM E 353, by spectrochemical methods, or by other analytical methods acceptable to purchaser.
3.1.1 Vendor may test for any element not listed in Table 1 and include this analysis in the report of 4.5. Limits of acceptability may be specified by purchaser (see 8.2.3).
3.1.2 Check Analysis
Composition variations shall meet the applicable requirements of AMS 2248.
3.2 Melting Practice
Castings and specimens shall be poured at the casting vendor’s facility either from a melt (see 8.2.4) of a master heat or directly from a master heat (see 8.2.5).
3.2.1 Revert (gates, sprues, risers, and rejected castings) may be used only in the preparation of master heats; revert shall not be remelted directly, without refining, for pouring of castings. Melting of revert creates a new master heat.
