RATIONALE

AMS5336J results from a Five-Year Review and update of this specification that adds strain rate control on tensile testing

(3.6.1.1), updates radiographic acceptance criteria (3.7.4.1), and adds a requirement to report exceptions to technical

requirements (4.5.2).

AMS5336J has been reaffirmed to comply with the SAE Five-Year Review policy.

1. SCOPE

1.1 Form

This specification covers a low-alloy steel in the form of investment castings.

1.2 Application

These castings have been used typically for small structural parts of intricate design requiring heat treatment to minimum

tensile strengths up to 150 ksi (1034 MPa), but usage is not limited to such applications.

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 by wet chemical methods in accordance

with ASTM E350, by spectrochemical methods, or by other analytical methods acceptable to purchaser (see 8.2.1 and

8.2.2).

3.1.1 Producer 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 AMS2259. The foundry shall not use the variation

allowances to determine conformance of castings or specimens to 3.1.

SAE INTERNATIONAL AMS5336™J Page 3 of 10

3.2 Melting Practice

Castings and specimens shall be poured at casting producer's facility either from a melt (see 8.2.4) of a master heat or

directly from a master heat (see 3.4.3 and 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.

3.2.2 Portions of two or more qualified master heats (see 3.4.2) may be melted together and poured into castings using

a procedure authorized by purchaser (see 8.2.6).

3.2.3 If modifications, such as alloy additions or replenishments (see 8.2.10), are made by the producer at remelt,

producer shall have a written procedure acceptable to purchaser that defines the controls, test, and traceability

criteria for both castings and separately-cast specimens. Control factors of 4.4.2.2 shall apply.

3.3 Condition

Castings shall be delivered in the normalized condition, or, when required, in the normalized and tempered condition

(see 3.5).

3.4 Test Specimens

Specimens shall be separately-cast, integrally-cast (see 8.2.7) or machined from castings, and shall conform to 3.2.

3.4.1 If specimens are separately-cast, producer shall have a written procedure acceptable to purchaser. Control factors

of 4.4.2.2 shall apply.

3.4.2 Each master heat shall be qualified by evaluation of chemical, hardness, and tensile specimens.

3.4.2.1 If alloy additions or replenishments are made at remelt as in 3.2.3, the frequency of sampling and testing used by

the producer for qualification to 3.4.2 shall be acceptable to purchaser.

3.4.2.2 Tensile tests of 3.4.2 are not required if these tests are conducted using integrally-cast specimens (4.3.3.2) or

specimens machined from castings (4.3.3.3).

3.4.3 Chemical Analysis Specimens

Shall be of any convenient size and shape.

3.4.4 Tensile Specimens

Shall be of standard proportions in accordance with ASTM A370 with 0.250 inch (6.35 mm) diameter at the reduced parallel

gage section.

3.4.4.1 Separately-cast and integrally-cast specimens may be either cast to size or cast oversize and subsequently

machined to 0.250 inch (6.35 mm) diameter.

3.4.4.2 When integrally-cast specimens and specimens machined from castings are specified, specimen size and

location shall be as agreed upon by purchaser and producer (see 8.2.8 and 8.6).

3.4.5 Hardness Specimens for Response to Heat Treatment

May be a representative specimen or a casting.
