Automotive Malleable Iron Castings

2003-04-11

CURRENT

J158_200304

This standard covers the hardness and microstructural requirements for malleable iron castings - ferritic, pearlitic, tempered pearlitic, and tempered martensitic grades used in automotive and allied industries. Castings shall be heat treated to meet this SAE Standard. The Appendix provides general information on the application of malleable iron castings and their chemical composition to meet hardness, microstructure, and other properties needed for particular service conditions. The mechanical properties in the Appendix are provided for design purposes. The specific grades, hardness range, and final heat treatment are shown in Table 1.

Grain Size Determination of Steels

1999-05-01

CURRENT

J418_199905

This classification for grain size comprises three sets of comparison charts to be used for determining grain size. These charts are presented in three categories as follows: Plate I - Untwinned grains (flat etch) Plate II - Twinned grains (flat etch) Plate IV - Austenite grains in steel (McQuaid-Ehn test or other test) Table 1 lists a number of materials and the comparison charts that are suggested for use in estimating their grain size by the comparison method. NOTE—The suggestions in Table 1 are based upon the customary practices in industry. For specimens prepared according to special techniques, the appropriate comparison chart should be selected on a structural appearance basis as described in the Scope.

Tensile Test Specimens

1999-05-20

CURRENT

J416_199905

When required, unless otherwise specified in the SAE Standards or Recommended Practices, tensile test specimens for metals shall be selected and prepared in accordance with this report. ASTM E 8, Methods of Tension Testing of Metallic Materials, gives more detailed information on tensile testing procedure, and ASTM E 4, Methods of Load Verification of Testing Machines, provides information on testing equipment calibration. In recommending these specimens for use in tensile tests it is not intended to exclude entirely the use of other test specimens for special materials or for special forms of material. It is, however, recommended that these specimens be used wherever it is feasible. Machining of specimens shall be done in such a manner as to avoid leaving severe machining strains in the material. Specimens shall be finished so that the surfaces are smooth and free from nicks and tool marks. All ragged edges shall be smoothed.
