1. Scope | ||||||||
1.1 This specification covers carbon steel castings for general applications that require up to 70 ksi (485 MPa) minimum tensile strength. 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]1.2.5 Class 1 and Class 2 steel castings shall be specified in accordance with 9.2. 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 non-conformance 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. |
