• ASTM A333 seamless steel pipe for low-temperature service and other applications with required notch toughness

ASTM A333 (ASME S/A-333) are standard specification for seamless and welded steel pipe for low-temperature service and other applications with required notch toughness. 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, and 11.
