SAE AMS 5590E pdf download.Nickel Alloy, Corrosion and Heat Resistant, Seamless Tubing 52.5Ni – 19Cr -3.0Mo – 5.1Cb – 0.90Ti -0.50Al – 18Fe Consumable Electrode or Vacuum lnduction Melted 1950 F(1066c) Solution Heat Treated.
1.1 Form:
This specification covers a corrosion and heat resistant nickel alloy in the form of seamless tubing.
1.2 Application:
This tubing has been used typically for fluid lines and structural components requiring high strength at cryogenic temperatures and for short-time service up to 1200 °F (649 °C) and oxidation resistance up to 18CC °F (982 °C), particularly those parts which are formed or welded and then heat treated to develop desired properties, 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 canceled and no superseding document has been specified, the last published issue of that document shall apply.

3.2 Melting Practice:
Alloy shall be produced by multiple melting using consumable electrode practice in the remelt cycle or shall be induction melted under vacuum. If consumable electrode remelting is not performed in vacuum, electrodes which have been produced by vacuum induction melting shall be used for remelting.
3.3 Condition:
Cold drawn, solution heat treated, and unless solution heat treatment is performed in an atmosphere yielding a bright finish, pickled as required. No specific solution heat treating instwctions are specified but it is recommended that the tubing be solution heat treated by heating in a suitable protective atmosphere to 1950°F ±25 (1066°C ± 14), holding at heat for not more than 30 minutes, and cooling at a rate equivalent to an air cool or faster.
3,4 Fabrication:
Tubing shall be produced by a seamless process. Surface finishes may be produced by pickling, bright annealing, or any method which will provide the required surface condition and which will not affect limits of wall thickness or corrosion resistance, with the exception that a centerless-ground finish is not acceptable. A light polish to improve external surface appearance may be employed.
3.5 Properties:
Tubing shall conform to the following requirements:
3.5.1 As Solution Heat Treated:
3.5.1.1 Tensile Properties: Tubing having nominal 00 of 0.125 inch (3.18 mm) and over with nominal wall thickness of 0.015 inch (0.38 mm) and over shall have the properties shown in Table 2, determined in accordance with ASTM E 8 or ASTM E 8M.
3.6.2 Tubing shall be tree from grease, oil or other foreign materials. Metallic flakes or particles shall not be collected on a clean white cloth drawn through the length of the bore of a test sample. Discoloration of the cloth, without the presence of flakes or particles, is acceptable.
3.7 Tolerances:
Shall conform to all applicable requirements of AMS 2263 or MAM 2263.
4. QUALITY ASSURANCE PROVISIONS:
4.1 Responsibility for Inspection:
The vendor of tubing shall supply all samples for vendor’s tests and shall be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the tubing conforms to specified requirements.
4.2 Classification of Tests:
4.2.1 Acceptance Tests: The following requirements are acceptance tests and shall be performed on each heat or lot as applicable:
4.2.1.1 Composition (3.1) of each heat.
4,2.1.2 Tensile properties (3.5.1 .1) and average grain size (3.5.1.2) of each lot as solution heat treated.
4,2.1.3 Tensile properties (3.5.2.1) of each lot after precipitation heat treatment.
4.2.1.4 Quality (3.6) and tolerances (3.7) of each lot.
4.2.2 Periodic Tests: The following requirements are periodic tests and shall be performed at a frequency selected by the vendor unless frequency of testing is specified by purchaser:
4.2.2.1 Flarability (3.5.1.3) of tubing as solution heat treated.
4.2.2.2 Hardness (3.5.22) of tubing after precipitation heat treatment.
4.3 Sampling and Testing:
Shall be in accordance with AMS 2371 and the following:
4.3.1 Specimens for flarability test (3.5.1.3) shall be full tubes or sections cut from a tube. The end of the specimen to be flared shall be Cut square, with the Cut end smooth and free from burrs, but not rounded.
