This specification covers hot-wrought alloy steel bars. The steel shall be made by one or more of the following primary processes: open-hearth, basic-oxygen, or electric-furnace. The primary melting may incorporate separate degassing or refining and may be followed by secondary melting using electro-slag remelting or vacuum arc remelting. Where secondary remelting is employed, the heat shall be defined as all of the cast product remelted from a single primary heat. The steel shall be furnished as strand cast or ingot cast. Immediately after hot forming, the bars shall be allowed to cool to a temperature below the critical range under suitable conditions to prevent imperfections caused by too rapid cooling. The bars shall be free of pipe, cracks, and flakes. Within the limits of good manufacturing and inspection practices, the bars shall be free of injurious seams, laps, segregation, or other imperfections which are due to their nature, degree, or extent, will interfere with the use of the material in machining or fabrication of suitable parts.1.1 This specification covers hot-wrought alloy steel bars. Bar applications include forging, heat treating, cold drawing, machining and many structural components (Note 1).NOTE 1: A guide for the selection of steel bars is contained in Practice A400.1.2 The bars shall be furnished in the grades specified in Table 1. Sections and sizes of bar steel available are covered in Specification A29/A29M. Hot-wrought alloy steel bars are produced in cut lengths and coils; the manufacturer should be consulted regarding sections and sizes available in coils, produced to a chemical composition.1.3 Some applications may require superior surface quality, or special chemical restrictions, metallurgical characteristics, heat treatment, or surface finishes which the purchaser may obtain by designating one or more of the available Supplementary Requirements.1.4 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.

This specification deals with Grade 80 heat-treated alloy steel chain for applications such as slings, lifting assemblies, and load binding. The alloy steel chain shall be made to a fully-killed fine austenitic grain process. Alloy steel chain may be made by the electric welding or gas welding process. The material shall be heat treated which includes quenching and tempering. Material's composition shall conform to the chemical requirements for carbon, phosphorous, sulfur, nickel, chromium, and molybdenum. The material shall conform to the mechanical property requirements for breaking force and elongation and to the dimensional requirements for the appropriate size chain. All chain shall be tested to at least the proof load.1.1 This specification covers Grade 80 heat-treated alloy steel chain for such applications as slings, lifting assemblies, and load binding. For overhead lifting applications, only alloy chain should be used.1.2 The chain grade is based on the nominal stress in the link at the design breaking force strength. It is calculated by taking the minimum breaking force load and dividing by two times the nominal cross-sectional area of the link.1.3 The values stated in either SI units or in other units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.3.1 Metric Units—Grade = 1/10 of the minimum breaking force in kilonewtons divided by two times the nominal cross-sectional area in square millimeters. = (MBF)/(0.005)(π)(d)(d)1.3.2 English Units—Grade = 0.000689 of the minimum breaking force in pounds divided by two times the nominal cross-sectional area in square inches. = (0.000689)(MBF)/(0.5)(π)(d)(d)1.3.3 MBF = minimum breaking force (lb or kN); d = chain diameter (in. or mm).NOTE 1: The above formulas are for round diameter links only. If different cross sections are used, the actual cross section of the link would need to be calculated and used.1.4 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.
