ASTM A 334/A 334M - 04a Standard Specification for Seamless and Welded Carbon and Alloy-Steel Tubes for Low-Temperature Service

American Society for Testing and Materials (ASTM). Current edition approved May 1, 2004. Published June 2004. Originally approved in 1951. Last previous edition approved in 2004 as A 334/A 334 6M – 04. 6 p. This specification covers several grades of minimum-wall-thickness, seamless and welded, carbon and alloy-steel tubes intended for use at low temperatures. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.
