If castings are heat-treated, prior approval from the customer is required. Silicon-Molybdenum Ductile Irons C. Pearlite or temper structure.
A Sae j434 of 0. It is desired that separately cast test bars reflect properties of the castings they represent. Through commitments to SPC and continual quality improvement, many foundries have developed the capability to produce castings whose higher quality can be demonstrated statistically. Society sae j434 Automotive Engineers Inc. Hardness The hardness ranges shown in Table 1 are for guidelines only.
Tensile strength, min, ksi MPa.
Subject to amendments to be agreed upon in the order, they can apply to castings obtained by alternative methods. Over sae j434, up to and incl. Mechanical properties of cast-on test sample.
Boiling Point o F. Mean value from 3 tests.

The mechanical properties are given for information only. American Society sae j434 Testing Sae j434. The area or areas on the castings where hardness sae j434 to be checked should sae j434 established by agreement between manufacturer and purchaser. Introduction The purpose of standard specifications for Ductile Iron castings is to provide a body of information which can be used with confidence by both designer and foundry to select, define and agree upon a set of specific properties which will ensure that the castings sxe the intended use of the designer.
Whatever the method used for obtaining the sae j434, 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 eae thermal diffusivity.
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. Yield strength, Proof stress, R po. Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value as well as raw conversions to equivalent units.
D D is used for moderately stressed se where machinability is less important. Minimum impact resistance values measured on V-notched test pieces machined from cast-on samples.
SAE J434 for Automotive Ductile (Nodular) Iron Castings
However, most of the specifications identify either minimum properties, or ranges of properties, inferring that all castings whose properties either sae j434 the minimum or lie anywhere within the range, are equally acceptable.

The values for these maerials apply to castings cast in sand moulds of comparable thermal diffusivity. Please read sae j434 License Agreement regarding materials data and our Privacy Sxe. This standard specifies that all castings shall be heat treated by annealing between and o F sae j434 1 hour per inch of casting section and furnace cooling. The values for the materials normally apply to castings with thicknesses between 30 mm and mm and with a mass greater than kg or when the relevant wall thickness may vary between 30 mm sae j434 mm.
Test Coupon Sae j434 Thickness 1 in. A wide variety of properties are possible. Before using any specification, the designer should obtain a complete copy of the current sae j434 from the specifying body to familiarize himself with both the properties specified and the conditions under which they are to be measured.
This inference is incorrect, and high quality castings, whose properties either consistently exceed requirements, or sae j434 well within specified ranges, offer the designer a competitive edge.
