ASTM A333 Low Temperature Steel Pipe
ASTM A333 (ASME S/A-333) Pipe 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. 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.

Scope - astm a333 pipe
ASTM A333 covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.
Material & Manufacture
The pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.
Heat Treatment Requirements
All seamless and welded pipe shall be treated to control their microstructure by the following methods: Normalizing per A 333/A 333M-05 section 4.2.1.1; section 4.2.1.2 or section 4.2.1.3 Quenched and Tempered per A 333/A 333M – 05 section 4.2.2.1 Double Normalized and Tempered per A 333/A 333M – 05 section 4.2.2.2
