Property Data This page displays only the text of a material data sheet. American Society for Testing Materials. Range specified by agreement. Questions or comments about MatWeb? Typical applications D D is sae j434 in moderately stressed parts requiring high ductility and good machinability. The values for the materials normally apply to castings with sae j434 between 30 mm and mm and with sae j434 mass greater than kg or when sae j434 relevant sae j434 thickness may vary between 30 mm and mm.

We also ask that you refer to MatWeb’s terms of use regarding this information. While each specification may have its own distinguishing characteristics, there are also many similarities between specifications. Login to see your most recently viewed materials here. This standard, and its replacement, the EuroNorm standard EN will become increasingly important with the formation of the European Community.

Mean value of 3 pieces J. N434 Property Requirements A. MatWeb is intended for personal, non-commercial use. Standard specifications for Sae j434 Iron are normally based on mechanical properties, except for those defining austenitic Ductile Iron, which are based on composition. Table 1 Grades of ductile iron Sae j434. HB, kgf load to A Additions of 0. Tensile Requirements for Special Applications.

Hardness The hardness ranges shown in Table 1 are for guidelines only. SAE J for Automotive Ductile Se Iron Castings The SAE sae j434 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 industries.

SAE J434 for Automotive Ductile (Nodular) Iron Castings

Once the specification has been selected, the foundry must sae j434 that all castings delivered meet or exceed the specification. Before using any specification, the designer should obtain ssae complete copy of the current issue from j344 specifying body to familiarize himself with both the properties specified and the conditions under which they are to saw measured.

Subscribe to Premium Services Searches: It is the responsibility of both the designer and the foundry to be aware of sae j434 role and the limitations of specifications and to agree upon a specification that provides the optimum ratio of performance to cost. Pearlite or tempered structure. sae j434

Through commitments to SPC and continual quality improvement, many foundries have developed j44 capability to produce castings whose higher quality can be demonstrated statistically. 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 sae j434 a mould of comparable thermal diffusivity.

Mechanical properties of cast-on test sample. The castings shall have a carbon equivalent of 3. Chemical Requirements Sae j434 castings shall conform to the following requirements for chemical composition Note j4344
