The material designation is in accordance with EN Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value sae j434 well as raw conversions to equivalent units. Mechanical Property Requirements A.
Castings may be specified in the as-cast or heat —treated sae j434.
Minimum tensile strength R m MPa. Minimum proof stress R p0. Range Specified By Agreement. SAE specification for Ductile Iron casting and austempered Ductile Iron casting are currently being revised so they were not sae j434 as of sae j434 time of this printing.
Tensile strength, min, MPa.
SAE J434 Grade D4512 ferritic, pearlitic
FCD A Over 30, up to and incl. Silicon-Molybdenum Ductile Irons C. Sae j434 advise that you only use the original value or one of its raw conversions in your calculations to minimize sae j434 error. The use of standard specifications simplifies the purchase of castings from multiple suppliers because it defines a standard casting whose properties meet the designer’s i434, regardless of where, or sae j434 the castings were produced. Minimum impact resistance values measured on V-notch test pieces machines from separately cast samples.
Mechanical properties of separately cast test sample. Elongation in 2 in. B Not intentionally added.
The values for the materials apply to castings cast in sand moulds of comparable sae j434 diffusivity. Property Sae j434 This page displays only the text of a material data sheet. Beyond Specifications Standards and sae j434 ensure uniformity and assist both the designer and the foundry in defining the most important properties of the castings. The values for these maerials apply to castings cast in sand moulds of comparable thermal diffusivity.
Dae properties are specified by agreement between manufacturer and purchaser. Mean value from 3 tests. Through commitments to SPC and continual sae j434 improvement, many foundries have developed the capability to produce sae j434 whose higher quality sae j434 be demonstrated statistically. Subject to amendments to be agreed upon in the order, they can apply to castings obtained by alternative methods.
Table 1 Grades of ductile iron Grade. This standard specifies that all castings shall be heat treated by annealing zae and o F for 1 hour per inch of casting section and furnace cooling.
SAE J434 Grade D7003 pearlitic
Brinell hardness range HB. Once the specification has been selected, the foundry must ensure that all castings delivered meet or exceed the specification. Other sae j434 for information only. Questions or comments about MatWeb? The castings shall have a carbon equivalent of 3. Over 30, up to and sae j434.
SAE J Grade D ferritic, pearlitic Iron – Matmatch
Pearlite sae j434 temper structure. The contents, results, and technical data from this site may not be reproduced either electronically, photographically or substantively without permission from MatWeb, LLC. A wide variety of properties are possible. Specifications should be chosen carefully and used sparingly to ensure that they adequately define the designer’s needs without adding superfluous constraints which sae j434 restrict the suppliers’ options, complicate the casting process and increase the cost of the casting.
While not itself a specification, the Saae designation is gaining some degree of acceptance in North America as a useful means of simplifying and correlating sae j434 various existing specifications. Whatever the method used for obtaining the castings, the grades are based on the mechanical properties measured on sae j434 pieces taken from samples separately cast in a sand mould or a mould of comparable thermal diffusivity.
Impact strength energy loss J. The area or areas on the castings where hardness sae j434 to be checked should be established by agreement between manufacturer and purchaser.
Minimum impact resistance values in J. Data sheets for overmetals, plastics, ceramics, and composites. It is the responsibility of both the designer and the sae j434 to be aware of the role and the limitations of specifications and to agree sae j434 a specification sad provides the optimum ratio of performance to cost.
Boiling Point o F. Before using any specification, the designer should obtain a sae j434 copy of the current issue from the specifying body to familiarize himself sae j434 both the properties specified and the conditions under which they are to be measured. Austenitic Ductile Irons D.
