(Specification)Standard Specification for Forged Grade 80 and Grade 100 Steel Lifting Components and Welded Attachment Links
Standard Specification for Forged Grade 80 and Grade 100 Steel Lifting Components and Welded Attachment Links
ABSTRACT
This specification covers forged alloy steel lifting components and welded coupling and master links for Grade 80 and Grade 100 alloy chain slings. The steel materials shall be melt processed either by electric process or oxygen blown process. The steel shall be fully killed and shall conform to the required austenitic grain size. Product analysis shall be performed on and the steel specimens shall conform to the required chemical compositions of nickel, chromium, molybdenum, phosphorus and sulfur. Proof tests shall be performed and the materials shall conform to the required values of working load and breaking force. Deformation test, breaking force test and fatigue test shall be performed on the steel materials.
SCOPE
1.1 This specification covers the requirements for forged alloy steel lifting components and welded coupling and master links for Grade 80 and Grade 100 alloy chain slings as described in Specification A906/A906M.
1.2 Two grades of components and welded links are covered:
1.2.1 Grade 80.
1.2.2 Grade 100.
1.3 This specification is a performance standard. Other standards apply to use of these products. Some of these standards are: OSHA 1910.184, ASME B30.9, and ASME B30.10.
1.4 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
