ASTM-A507:16(R2021) pdf free download – Standard Specification for Drawing Alloy Steel, Sheet and Strip, Hot-Rolled and Cold- Rolled.
6.1.1 Standard steels listed in Table 1 are those commonly produced for drawing alloy-steel sheet and strip.
6. 1.2 Nonstandard steel grades may be specified, using the ranges and limits shown in Table 2.
7. Metallurgical Structure
7. 1 Micro structure:
7. 1.1 Requirements—At least 75 % of the carbide micro- structure shall be of the globular type.
7.1.2 Number of Tests—The number of tests shall be in accordance with the producer’s standard quality control procedures. A specific number of tests is not required, but the material shall be produced by manufacturing practices established to assure compliance with the specified requirements.
The material shall he suhected to mill tests and inspection procedures to assure such compliance. For government procurement, mill tests and inspection procedures utilized to show conformance to the microstructure requirements shall be made available on request.
8. Mechanical Requirements
8. 1 Tension and Hardness Tests:
8. 1 . 1 Requirements—When tension tests or hardness tests, or both arc specified on the order, the test results shall conform to the requirements specified on the order. Yield strength. tensile strength, and elongation requirements may be specified. The tensile properties will vary depending on the chemical composition, condition, and heat treatment.
Rockwell hardness requirements may be specified, providing the requirements are compatible with the tension test requirements.
8.1.2 Number of Tests—Two tension tests and two hardness tests, when specified, shall be taken at random from each heat (cast) and heat treatment lot.
9. Other Tests and Requirements
9.1 End Use Suitability:
9.1.1 When steel is to be furnished in the spheroidizeannealed condition, the user and producer shall review any part(s) to be produced to reach adequate agreement on capability to produce said parts.
9.1.2 Material in the spheroidize-annealed condition generally work hardens and may require stress-relief-annealing between drawing operations.
10. Workmanship, Finish, and Appearance
10. 1 Surface Finish:
10. 1.1 Hot-Rolled-—Unless otherwise specified, hot-rolled material shall he furnished descaled and oiled. When required, the material may be specified to be furnished not oiled.
10. 1 .2 Cold-Rolled—Unless otherwise specified, cold-rolled material shall be furnished with a commercial dull matte finish and shall he oiled. When required, the material may he specified to he furnished not oiled.
10.2 Edges:
10.2.1 Hot-Rolled—Unless otherwise specified, hot-rolled material shall be furnished with Mill Edge. The material may be specified to have other types of edges, in accordance with Specification A505.
10.2.2 Cold-Rolled—Unless otherwise specified, cold-rolled sheet shall be furnished with Cut Edge and cold-rolled strip shall be furnished with No. 3 Edge. The material may be specified to have other types of edges, in accordance with Specification A505.
