ASTM A334 (ASME S/A-333) Pipes grades permit low temperature service. This specification covers nominal (average) walled pipe almost exclusively in seamless. Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse effect on low-temperature impact properties. A334 pipe is furnished to nine different grades designated by numbers 1, 3, 4, 6, 7, 8, 9, 10, & 11.
