SAE J434 for Automotive Ductile (Nodular) Iron Castings
Typical Hardness Range MPa. Pearlite or temper structure. Silicon-Molybdenum Ductile Irons C. A wide variety of properties are possible. Minimum proof stress R p0. Tensile strength, min, psi. Tensile strength, min, MPa.
SAE J434 Grade D4512 ferritic, pearlitic
Test Coupon Section Thickness. The grades, mechanical properties and metallurgical description are shown in Table 1. Range specified by agreement. SAE J for Automotive Ductile Nodular Iron Castings The SAE standard covers the minimum mechanical properties measured on separately cast test pieces of varying thickness and micro-structural requirements for ductile iron castings used in automotive and allied saf.
The raw materials and production methods used by the foundry to provide conforming castings are not normally restricted by the designer or the specification unless j34 specification includes such instructions, or the designer and foundry agree to append additional instructions to a specification.
Charpy V-notch, ft-lbf min, average 3 tests. Impact strength energy loss J.
Yield strength, min, psi. To see MatWeb’s complete data sheet for this material including material property data, metal compositions, material suppliers, etcplease click the button below.
ase Tensile strength, R m1 min. Subject to amendments to be agreed upon in the order, they can apply to castings obtained by alternative methods.
D D is used for more highly stressed parts. UNS numbers and corresponding Zae specifications. Minimum impact resistance values in J. Mean value of 3 pieces J. The area or areas on the castings where hardness is to be checked should be established by agreement between manufacturer and purchaser. Tensile strength, min, ksi MPa. Whatever the method used for obtaining the castings, the grades are based on the mechanical properties measured on test pieces taken from samples separately cast in a sand mould or a mould of comparable thermal diffusivity.
Table 1 Grades of ductile iron. Further values are given in annex D for guidance. Castings may be specified in the as-cast or heat —treated condition. The use of standard specifications simplifies j4344 purchase of castings from multiple suppliers because it defines a standard casting whose properties meet the designer’s needs, regardless of where, or how the castings were produced.

The properties of a cast-on test piece cannot reflect exactly the properties of the casting itself, but can be a better approximation than those obtained on a separately cast sample. A Additions of 0.
