MATERIAL SPECIFICATION

AMS5696™

REV. F

Issued 1984-07

Noncurrent 2008-03

Reaffirmed 2021-05

Revised 2025-10

Superseding AMS5696E

(R) Steel, Corrosion- and Heat-Resistant, Welding Wire,

19Cr - 12.5Ni - 2.5Mo (316L)

(Composition similar to UNS S31683)

RATIONALE

AMS5696F is the result of a Five-Year Review and update of the specification. The revision updates the title to include the

trade name (see 8.5), adds country of origin to reporting (see 4.4), allows prior revisions (see 8.3), and prohibits

unauthorized exceptions (see 3.4, 4.4.1, 5.3.1, and 8.4).

1. SCOPE

1.1 Form

This specification covers a corrosion- and heat-resistant steel in the form of welding wire.

1.2 Application

This wire has been used typically as bare wire filler metal for gas-tungsten-arc or gas-metal-arc welding of corrosion- and

heat-resistant steels and alloys, but usage is not limited to such applications.

1.2.1 The relatively high ferrite content promotes weldability by combating micro-fissuring and minimizing cracking in

heavy sections but limits use of the wire to applications not operating in the sigma-forming temperature range.

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 Wire shall meet the technical requirements of AWS A5.9/A 5.9M ER316L and the following:

3.2 Quality

Wire, as received by the purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and

from imperfections detrimental to welding operations, operation of welding equipment, or properties of the deposited

weld metal.

3.3 Sizes and Tolerances

Wire shall be supplied in the sizes and to the tolerances specified in AWS A5.9/A5.9M. Smaller diameter wires, when

ordered, shall be supplied in sizes and tolerances shown in 3.3.1.

3.4 Exceptions

Any exception shall be authorized by the purchaser and reported as in 4.4.1.

4. QUALITY ASSURANCE PROVISIONS

4.1 Responsibility for Inspection

The producer of wire shall supply all samples for the producer’s tests and shall be responsible for the performance of all

required tests. The purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to

ensure that the wire conforms to specified requirements.

4.2 Classification of Tests

4.2.1 Acceptance Tests

Composition (see 3.1), sizes and tolerances (see 3.3), and alloy verification (see 5.2) are acceptance tests and shall be

performed on each heat or lot as applicable.

4.3 Sampling and Testing

Sampling and testing shall be in accordance with AWS A5.01 S3, testing schedule 5 or J.

4.4 Reports

The producer of wire shall furnish with each shipment a report showing the producer’s name, the country where the metal

was melted (e.g., final melt in the case of metal processed by multiple melting operations), and the results of tests for

composition and ferrite number of each heat. The report shall state that the wire conforms to the other technical requirements

and shall include the purchase order number, heat and lot numbers, AMS5696F, nominal size, and quantity.

4.4.1 When material produced to this specification has exceptions taken to the technical requirements listed in Section 3

(see 5.3.1), the report shall contain a statement “This material is certified as AMS5696F(EXC) because of the

following exceptions:” and the specific exceptions shall be listed.

4.5 Resampling and Retesting

Resampling and retesting shall be in accordance with AWS A5.01.

5. PREPARATION FOR DELIVERY

5.1 Wire shall be supplied either on spools in one continuous length for machine welding or in cut lengths for manual

welding, as ordered. Wire on each spool or in each package of cut lengths shall be from the same heat of steel.

5.2 Alloy Verification

Wire on each spool or in each package of cut lengths shall be alloy verified by a method acceptable to the purchaser. The

alloy verification procedures of ARP4926 are recommended.

5.2.1 An 8-inch (203-mm) length of wire shall be accessible at both ends of each spool for alloy verification.

5.3 Identification

Wire shall be identified in accordance with AMS2816 unless AMS2819 or another method is specified by the purchaser.

5.3.1 When technical exceptions are taken (see 4.4.1), the material shall be marked with AMS5696(EXC).
