ASTM A333 Low Temperature Pipe
ASTM A333 specification covers nominal (average) walled pipe almost exclusively in seamless. Several ASTM A333 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. A333 pipe is furnished to nine different grades designated by numbers 1, 3, 4, 6, 7, 8, 9, 10, & 11. Discussed herein are Grades 1 and 6.
