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.

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

Straight-seam, or spiral-seam steel pipe, 4 in. and over in

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.

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

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.

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,
