2.2.2 Shell and Base Plates. For more information on this subject, see Tables B-1 through B-11 in Nonman- datory Appendix B. (a) Shell and base plates typically may be of one or more of the following structural quality materials: (1) Carbon steels conforming to the ASTM A 36, A 283, or A 529 Specifications. (2) High-strength, low alloy steels conforming to the ASTM A 242, A 572, or A 588 Specifications. (3) Stainless steels conforming to the ASTM A 666 Specification. (4) Stainless chromium-nickel steel clad plate con- forming to ASTM A 264 and nickel-base alloy clad steel conforming to ASTM A 265 may be considered for use as shell plate. (5) Metals listed in Materials Appendix (i.e., Non- mandatory Appendix B), Table B-9 may be used not only as sheet linings and cladding but also as solid plate for shell plates. (b) Pressure vessel quality carbon steels such as ASTM A 285, A 515, and A 516; alloy steels such as ASTM A 387; and stainless steels such as ASTM A 240 may be substituted for structural quality materials as appropriate. (c) Carbon steels such as ASTM A 516, Grades 55 through 70 and low alloy steels such as ASTM A 517, Grades A through T and ASTM A 537 are usually speci- fied for service temperatures as low as −50°F (−46°C). Nickel-containing alloy steels such as ASTM A 203, Grades A and B are usually used for service tempera- tures as low as −75°F (−59°C); and ASTM Grades D, E, and F are often used for service temperatures of −150°F (−101°C). Nickel-containing alloy steels and nickel stain- less steels are used for even lower temperatures. Suppli- ers ofstructural quality steels will provide data on notch toughness when specified. (d) Protection against corrosion and/or oxidation may be required on interior and/or exterior surfaces depending on the materials utilized and the conditions encountered. Section 3 should be consulted and utilized as appropriate. (e) Creep rupture tensile stresses for sustained load- ing and high-temperature service conditions must be considered as given in para. 4.4.8. 2.2.3 Stiffeners and Structural Braces and/or Framework (a) Stiffeners and structural braces and/orframework typically may be of one or more of the following mate- rials: 5 (1) carbon steels conforming to the ASTM A 36, A 283, or A 529 Specifications (2) high-strength, low alloy steels conforming to the ASTM A 242, A 572, or A 588 Specifications (3) stainless steels conforming to the ASTM A 240 or A 666 Specifications or nickel-containing alloys hav- ing compositions similar to those of the shell plate (b) Protection may be required against corrosion for components exterior to the shell and against corrosion and/or oxidation for components on the shell interior. Section 3 should be consulted and utilized as appro- priate. 2.2.4 Guy Wires, Cables, or Fittings (a) Guy wires and cables typically may be of one or more of the following materials, and consideration should be given to the initial stretch of the material: (1) aluminum-coated steel wire strand conforming to the ASTM A 474 Specification (2) zinc-coated (galvanized) steel wire strand con- forming to the ASTM A 475 and A 586 Specifications (3) zinc-coated (galvanized) steel wire rope con- forming to the ASTM A 603 Specification (4) stainless steel wire strand conforming to the ASTM A 368 Specification (b) Fittings for guys and cables should comply with manufacturers’ standards and be of aluminum-coated, zinc-coated (galvanized), or stainless steel as appro- priate. Aluminum and zinc coating weights and stain- less steel grade should match those of the guys or cables on which they are used. 2.2.5 Anchor Bolts, Washers, and Nuts (a) Anchor bolts may be of threaded bolt and stud stock normally used as connectors, or of round stock of structural material that may be threaded. They are typically one of the following specifications: (1) carbon steel threaded fasteners conforming to the ASTM A 307 Specification (2) carbon steel bolts for general applications con- forming to the ASTM A 449 Specification (3) alloy steel bolts, studs, and threaded fasteners conforming to the ASTM A 354 Specification (4) alloysteel boltsandstudswithenhancedimpact properties conforming to the ASTM A 687 Specification (5) carbon steel conforming to the ASTM A 36 Spec- ification (6) high-strength, low alloy steels conforming to the ASTM A 572 or A 588 Specification (b) Material for washers shall conform to the ASTM F 436 Specification and correspond to the anchor bolt material.
