Designation A1001 − 01 Reapproved 2015Standard Specification forHigh Strength Steel Castings in Heavy Sections1This standard is issued under the fixed designation A1001; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers cast alloy steels in the normal-ized and tempered or quenched and tempered condition, insection sizes through 37 in. 940 mm, suitable for high straingradient conditions such as those encountered in hooks,shackles, support frames, and other lifting devices. The classesof steel in this specification are weldable only with qualifiedprocedures.1.2 Section range and class selection will depend on designand service conditions. Users should note that this specificationcontemplates mechanical property gradients.1.3 The values stated in inch-pound units or SI units are tobe regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system are notexact equivalents; therefore, each system must be used inde-pendently of the other. Combining values from the two systemsmay result in non-conformities with the specification. Inch-pound units are applicable for material ordered to this Speci-fication and SI units for material ordered to this Specification.1.4 If, by agreement, castings are to be supplied in apartially completed condition, that is, all of the provisions ofthe product specification have not been filled, then the materialmarking see Section 15 and certification see Section 14 areto reflect the extent to which the product specification require-ments have been met.2.
