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 
  	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.

	temperature service.  Furnished in one of three grades, A, B,
	or C.  Suitable for bending, flanging, and similar forming

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 

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,
