ASTM
Number		Explanation				

A-333	Covers nominal wall seamless and welded carbon and alloy steel 
	pipe intended for low temperature service.  (-50 to -320F).  
	Several grades are covered including Grades 1, 3, 4, 6, 7, 8, 
	and 9.

A-334	Covers six grades of seamless or welded carbon and alloy steel 
	tubes intended for use at low temperatures (-50 to -320F).

A-335	Covers nominal wall seamless alloy steel pipe intended for high 
	temperature service.  Pipe ordered to this specification shall
	be suitable for bending, flanging, and similar forming 
	operations, and for fusion welding.  Selection will depend upon 
	design, service conditions, mechanical properties, and high 
	temperature characteristics.  This specification covers twelve 
	grades, most common of which are Grades 1,5 7, 9, 11 and 22.

A-338	This specification covers malleable iron flanges, pipe fittings
	and valve parts, including parts to be assembled for use in 
	railroad, marine and other heavy duty service applications 
	where fittings furnished in accordance American National 
	Standard for Malleable Iron Threaded Fittings, Class 150 and 
	300 (ANSI B16.3) are not considered adequate.

A-350 	This specification covers several grades of carbon and 
	low-alloy steel forged or ring-rolled flanges, forged 
	fittings and valve intended primarily for low-temperature 
	service and requiring notch toughness testing.  They are 
	made to specified dimensions, or to dimensional standards, 
	such as the ANSI and API specifications referenced in the 
	full ASTM Specification.  
	Although this specification covers come piping components 
	machined from rolled bar and seamless tubular materials.  
	It does not cover raw material produced in these product 
	forms.

A-351 	This specification covers austenitic and austenitic-ferritic
	(duplex) steel castings for valves, fittings and other 
	pressure-containing parts.  Grades included in this 
	specification are CF3, CF8, CF3M, CF8M, CF3MN and so on.

A-352 	This specification covers steel castings for valves, flanges, 
	fittings and other pressure-containing parts intended 
	primarily for low-temperature service.  This specification
	contains the following grades LCA, LCB, LCC, LC1, LC2, 
	LC2-1, LC3, LC4, LC9 and CA6NM.

A-358 	This specification covers electric-fusion-welded 
	austenitic chromium-nickel alloy steel pipe suitable for 
	corrosive or high-temperature service, or both.  
	(Although no restrictions are placed on the sizes of pipe 
	which may be furnished under this specification, commercial 
	practice is commonly limited to sizes not less than NPS 8).

A-387	This specification covers chromium-molybdenum alloy steel 
	plates intended primarily for welded boilers and pressure vessels 
	designed for elevated temperature service.  It covers the following 
	grades, 2, 5, 9, 11, 12, 21, 21L, 22, 22L and 91.

A-403 	This specification covers two general classes, WP 
	and CR, of wrought austeitic stainless steel fittings of 
	seamless and welded construction covered by the lastest 
	revision of ANSI B 16.9, ANSI B 16.11, ANSI B 16.28, 
	MSS-SP79 and MSS-SP95.  Fittings differing from these ANSI 
	and MSS standards shall be identified with the marking "S9".

A-405	Covers on grade (P-24) of seamless ferritic alloy-steel pipe 
	specially heated treated for high temperature service.

A-420 	This specification covers wrought carbon steel and 
	alloy steel fittings of seamless and welded construction 
	covered by the lastest revision of ANSI B 16.9, 
	ANSI B 16.11, ANSI B 16.28, MSS-SP79 and MSS-SP95.  
	Fittings differing from these ANSI and MSS standards shall 
	be identified with the marking "S6".  These fittings are 
	for use in pressure piping and pressure vessel service 
	at low temperatures.

A-500	Covers cold formed welded and seamless carbon square, 
	rectangular, or special shape structural tubing for general 
	structural purposes.  Covers three grades:
	Grade A - 39,000 psi Min. Yield
	Grade B - 46,000 psi Min. Yield
	Grade C - 50,000 psi Min. Yield

A-501	Covers hot formed welded and seamless carbon steel, rectangular, 
	square, or special shape tubing for general structural purposes.

A-512	This specification covers cold-drawn buttweld carbon steel tubes 
	for use as mechanical tubing.  It covers round, square, 
	rectangular, and special shapes.  Common grades in warehouse 
	stock are 1010, 1015, and 1020.

A-513	This specification covers electric-resistance welded 
	carbon and alloy steel tubing for use as mechanical tubing.  
	It covers round, square, rectangular, and special shapes made 
	from hot or cold rolled steel.  It covers "as welded," 
	"sink drawn," "mandrel drawn," and "special smooth inside 
	diameter."  

A-519	This specification covers a multitude of grades of 
	carbon and alloy steel seamless mechanical tubing.  It covers 
	both hot finished and cold drawn tubing up to and including 
	12-3/4 in. outside diameter with wall thickness as required.

A-524	Covers seamless carbon steel pipe for process piping 
	applications.  Suitable for welding, bending, flanging, and 
	similar forming operations.  Two grades are covered: Grade I 
	(0.375 in. wall thickness and under) and Grade II 
	(greater than 0.375 in. wall thickness).

A-618	Covers three grades of hot-formed welded and seamless 
	high-strength low-alloy square, rectangular, round or special 
	shape tubing for use in bridge or building construction and 
	general structural purposes.

A-671	Covers electric-fusion-welded steel pipe with filler 
	metal added, fabricated from pressure vessel quality plate of 
	several analyses and strength levels and suitable for service 
	at atmospheric and lower temperatures.

A-672	Covers electric-fusion-welded steel pipe with filler 
	metal added, fabricated from pressure vessel quality plate of 
	several analyses and strength levels and suitable for 
	high-pressure service at moderate temperatures.

A-691	Covers electric-fusion-welded carbon and alloy steel 
	pipe with filler metal added, fabricated from pressure vessel 
	quality plate of several analyses and strength levels and 
	suitable for high-pressure service at high temperatures.
