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.
