ASTM A47 covers ferritic malleable castings intended for general use at temperatures from normal ambient to approximately 750°F. A47 castings are limited to one available grade: grade 32510 for imperial castings, grade 22010 for metric castings.
A47 Mechanical Properties
| Grade | Tensile, min | Yield, min | Elongation, min% | Hardness, typical |
|---|---|---|---|---|
| 32510 (English) | 50,000psi | 32,500psi | 10 in 2” | 156 HBN |
| 22010 (Metric) | 340MPa | 220MPa | 10 in 50mm | 156 HBN |
Casting Examples
Popular examples of castings often made to ASTM A47 include Round Malleable Washers, Shear Plates and Ogee Washers.
