ASTM A / AM – 14e1 Standard Specification for Steel Castings Suitable for Pressure Service
This abstract is a brief summary of the referenced standard. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Recording-type pyrometers shall be used to control the furnace temperature. Property Data This page displays only the text of a material data sheet. Product analysis tolerances for stainless grades are not presently applicable pending development of these limits.
This specification covers low-alloy steel and martensitic stainless steels in the normalized and tempered, or quenched and tempered conditions, suitable for pressure-containing parts. Preliminary heat treatment and multiple tempering are permitted. Please contact us at webmaster matweb.

Click here to view all the property values for this datasheet as they were originally entered into MatWeb. Minimum temperature unless range is specied. The conversion given is based on CA6NM test coupons. MatWeb is intended for personal, non-commercial use. Login to see your most recently viewed materials here. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
The weldability of the classes in this specication varies from readily weldable to weldable only with adequate precautions, and the weldability of each class should be considered prior to assembly by fusion welding.
All castings shall receive the specified heat treatment requirement: 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: Combining values from the two systems may result in nonconformance with the specication.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Martensitic, Normalized and tempered; Quenched and tempered Key Words: Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. 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.
Examination of Weld Preparation S Other surface discontinuities shall meet the visual acceptance standards specied in the order. A number in parentheses indicates the year of last reapproval. For each reduction of 0. Unacceptable visual surface discontinuities shall be removed and their removal veried by visual examination of the resultant cavities. Other higher specied minimum average and single values may be used upon agreement between the manufacturer and the purchaser.
D Double temper with the nal temper at a lower temperature than the intermediate temper. We appreciate your input.
