Description of ASTM-A27/A27M 2017
1.1 This specification covers carbon steel castings for general applications that require up to 70 ksi (485 MPa) minimum tensile strength.
Note 1: The grades covered by this specification represent materials that are suitable for assembly with other steel castings or wrought steel parts by fusion welding. It is not intended to imply that all these grades possess the same degree of weldability or that the same welding techniques can be used on all castings. It is the responsibility of the purchaser to establish for himself a suitable welding technique.
1.2 Several grades and two classes of steel castings are covered, as indicated below. The grade and class desired shall be specified by the purchaser.
1.2.1 Grade N-1—Chemical analysis only.
1.2.2 Grade N-2—Heat treated but not mechanically tested.
1.2.3 Grade U-60-30 [415-205]—Mechanically tested but not heat treated.
1.2.4 Grades 60-30 [415-205], 65-35 [450-240], 70-36 [485-250], and 70-40 [485-275]—Heat treated and mechanically tested.
1.2.5 Class 1 and Class 2 steel castings shall be specified in accordance with .
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
