The steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, vanadium, boron, and copper. Other surface discontinuities shall meet the visual acceptance standards specied in the order. Other temperatures may be used upon agreement between the manufacturer and the purchaser, in which case S 8.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. We also ask that you refer to MatWeb’s terms of use regarding this information.

Combining values from the two systems may result in non-conformance with the standard. Examination of Weld Preparation S Within the text, the SI units are shown in brackets. Click here to view all the property values for this datasheet as they were originally entered into MatWeb. All castings shall receive the specified heat treatment requirement: It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Other higher specied minimum average and single values may be used upon agreement between the manufacturer and the purchaser.

Tensile properties of the steel shall conform to the requirements for tensile strength, yield strength, elongation, reduction of area, hardness, and maximum thickness. MatWeb is intended for personal, non-commercial use.


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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Unacceptable visual surface discontinuities shall be removed and their removal veried by visual examination of the resultant cavities. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.

Charpy Impact Test S8. The intermediate and nal PWHT temperatures shall be the same as the intermediate and nal tempering temperatures, respectively, as the original heat treatment of the castings.

Users should note that hardenability of some of the grades mentioned may restrict the maximum size at which the required mechanical properties are obtained. Magnetic Particle Inspection S5. Combining values a48 the two systems may result in nonconformance with the specication. Preliminary heat treatment and multiple tempering are permitted. Re—examination of the weld repair by radiography when Supplementary Requirement S 5 has been specied will not be necessary when an applicable surface inspection method was used to locate the discontinuity except for the following: Questions or comments about MatWeb?

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Recording-type pyrometers shall be used to control the furnace temperature.

Product analysis tolerances for stainless grades are not presently applicable pending development of these limits.
