Only general information is presented here. Please contact ASTM for greater detail. ASTM Number Explanation A-48 This specification covers gray iron castings intended for general engineering use where tensile strength is a major consideration. A-53 Covers seamless and welded black and galvanized steel Pipe furnished in the following types and grades: Type F - furnace Butt Welded (also known as continuous Weld) 1/8 in. to 4 in. NPS Type E - Electric-Resistance Welded, Grades A and B 1/8 in. To 24 in. NPS Type S - Seamless, Grades A and B 1/8 in. to 26 in. NPS Except for Type F, pipe ordered to this specification is suitable For forming, bending, and flanging. Grade B, the most common, has a minimum yield of 35,000 psi. A-72 Welded wrought iron pipe in Std. XS, and XXS weights suitable for fabrication. More highly resistant to some types of corrosion than carbon steel, astm 72 is suited for protective ciating such as galvanizing. Although highly resistant to vibration, wrought iron has a somewhat low tensile strength due to a low carbon content. A-105 This specification covers forged carbon steel piping components for ambient and higher temperature service in pressure systems. Included are flanges, fittings, valves and similar parts ordered either to dimensions specified by the purchaser or to dimensional standards such as the ANSI and API specifications referenced in the full ASTM Specification. Forgings made to this specification are limited to a maximum weight of 10000 lb or 4540 kg. Larger forgings may be ordered to Specification A 266. Tubesheets and hollow cylindrical forgings for pressure vessel shells are not included within the scope of this specification. Although this specification covers some piping components machined from rolled bar and seamless tubular products, it does not cover raw material produced in these forms. A-106 Covers seamless only carbon steel pipe for high- temperature service. Furnished in one of three grades, A, B, or C. Suitable for bending, flanging, and similar forming operations. A-126 This specification covers three classes of gray iron for castings intended for use as valve pressure retaining parts, threaded and flanged pipe fittings and flanges. A-134 Covers electric-fusion-(arc)-welded straight seam or spiral Seam plate pipe 16 in. and over in diameter, with wall thicknesses up to 0.75 in. This pipe is intended for conveying liquid, gas or vapour. A-135 Covers two grades of electric-resistance-welded steel pipe (A and B) 30 in. diameter and under. Pipe is intended for conveying liquid, gas or vapour; and only grade A is adapted for flanging and bending. A-139 Covers five grades (A and E) of electric-fusion-(arc)-welded, Straight-seam, or spiral-seam steel pipe, 4 in. and over in Diameter with nominal wall thicknesses up to 1.00 in. Has different mechanical properties than standard plate grades. Used for conveying liquid, gas or vapour. A-161 Covers seamless, hot finished and cold drawn, low carbon and carbon-molybdenum steel still tubes, for use in carrying fluids At elevated temperatures and pressures in various types of Heaters. This specification includes tubes 2 to 9 in. O.D. Inclusive and over 0.220 in. in minimum wall thickness. A-178 Covers electric-resistance-welded tubes made of carbon steel And intended for use as boiler tubes and superheater flues. Includes tubes 1/2 in. to 5 in. O.D. and 0.035 to 0.320 in. in Minimum wall thickness. A-179 Covers seamless cold drawn low carbon steel tubes for tubular head transfer apparatus. Includes sizes 1/8 to 3 in. O.D. inclusive. A-182 This specification covers forged low alloy and stainless steel piping components for use in pressure systems. Included are flanges, fittings, valves and similar parts to specified dimensions or to dimensional standards such as the ANSI specifications referenced in the full ASTM Specifications. A-192 This specification supersedes A-83 and covers seamless carbon steel boiler and superheater tubes for high pressure service. Includes sizes 1/2 to 7 in. O.D. and 0.085 to 1.000 in. minimum wall thickness. A-197 This specification covers malleable irons for castings manufactured by the cupola process. A-199 Covers several grades of chromium-molybdenum and chromium- molybdenum-cilicon seamless cold drawn intermediate alloy steel Tubes for head exchangers, condensers, and similar heat transfer apparatus. Includes sizes 1/8 in. to 3 in. inclusive in O.D. A-200 Covers same grades as A-199 except use and size range varies. This specification covers sizes 2 to 9 in. in O.D. and wall thickness over 0.220 min. A-203 This specification covers nickel-alloy steel plates intended primarily for welded pressure vessles. It covers five grades, A, B, D, E and F. A-204 This specification covers molybdenum-alloy steel plates, intended particularly for welded boilers and other pressure vessels covering three grades, A, B and C. A-209 Covers three grades of seamless carbon-molybdenum alloy steel Boiler and superheater tubes. Includes sizes 1.2 to 5 in. in O.D. and 0.035 to 0.500 in minimum wall thickness. A-210 Covers seamless medium carbon steel boiler tubes and boiler flues including safe ends, arch and stay tubes, and superheater tubes. Includes sizes 1/2 to 5 in. in O.D. and 0.035 to 0.500 in. in minimum wall thickness. A-211 Covers spiral welded steel or iron pipe 4 to 48 in. in diameter, and 0.0625 to 0.6875 in. in wall thickness. Intended for conveying liquid, gas, or vapour. A-213 This specification covers minimum-wall-thickness, seamless ferritic and austenitic steel, boiler and superheater tubes and austenitic steel heat-exchanger tubes, designated Grades T5, TP304, etc. These steels are referenced in the full ASTM Specification. A-216 This specification covers carbon steel castings for valves, flanges, fittings or other pressure-containing parts for high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by fusion welding. The three grades included are WCA, WCB and WCC. A-217 This specification covers martensitic stainless steel and alloy steel castings for valves, flanges, fittings and other pressure-containing parts intended primarily for high-temperature and corrosive service. The grades included in this specification are WC1, WC4, WC5, WC6, WC9, WC11, C5, C12 AND CA15. A-234 This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction covered by the lastes revision of ANSI B 16.9, ANSI B 16.11, ANSI B 16.28, MSS-SP79 and MSS-SP95. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures. Fittings differing from these ANSI and MSS standards shall be identified with the marking "S9". A-240 This specification covers chromium, chromium-nickel and chromium-manganese-nickel stainless and heat-resisting steel plate, sheet and strip for pressure vessels. A-249 This specification covers nominal-wall-thickness welded tubes made from the austenitic steels, referenced in the full ASTM Specification, with various grades intended for such use as boiler, superheater, or condenser tubes. A-252 Covers welded and seamless steel pipe for piling application or Permanent load carrying member. Available in Grades 1, 2 and 3 To meet physical properties as required. A-269 This specification covers grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resisting and low or high-temperature service, as referenced in the full ASTM Specification. A-278 This specification covers gray iron for castings suitable for pressure-containing parts for use at temperatures up to 650F. A-297 This specification covers iron-chromium and iron-chromium- nickel alloy castings for heat-resistant service. A-311 Covers stress-relieved cold-drawn carbon steel bars produced To mechanical property requirements.
