  • Description
  • Specification
  • Standard
  • Process
  • Packing
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.

*For Grade 1 and 6, each reduction of 0.01% C below 0.30%, an increase of 0.05 % Mn above 1.06 % would be permitted to a max. of 1.35%.
*For Grade 6, the limit for columbium may be increased up to 0.05 % on heat analysis and 0.06 % on product analysis.
*Generally, the carbon equivalent C.E = [C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15] shall not exceed 0.43% by heat analysis.
