SAE AMS 5349C:2000 pdf download Steel, Corrosion Resistant, Investment Castings 1 3Cr Free Machining; Hardened and Tempered
1 . SCOPE:
1 .1 Form:
This specification covers a corrosion resistant steel in the form of investment castings.
1 .2 Application:
These castings have been used typically for small parts up to 1 000 °F (538 °C), but usage is not limited to such applications. Corrosion resistance is lower than that of AMS 5350, but machinability is better.
1 .3 Classification:
Castings are classified by chemistry as follows:
Type 1 – Sulfur content
Type 2 – Selenium content
1 .3.1 Unless a specific type is ordered, either type may be supplied.
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 canceled 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 by wet chemical methods in accordance with ASTM E 353, by spectrochemical methods, or by other analytical methods acceptable to purchaser (See 8.2.1 and 8.2.2).
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.
3.1 .3 Unless otherwise specified by purchaser, either composition may be supplied.
3.2 Melting Practice:
Castings and specimens shall be poured at 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).
