What is the ASTM A333 Steel Pipe?
ASTM A333 steel pipe is the standard specification for seamless and welded carbon and alloy steel pipe for low-temperature service or other applications requiring notch toughness. There are several grades of ferritic steel covered by this standard: Grade, Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10, and Grade 11. Metals-Piping provides ASTM A333 steel pipes made by the seamless or welded process with the addition of no filler metal in the welding operation except that Grade 4 shall be made only by seamless process. The pipe shall be furnished free of welding repair, either radiographically tested or ultrasonically examined.

*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.
