Standard

ASTM A333/A333M

ASTM 333/A 333M covers nominal (average) wall seamless and welded carbon and alloy steel pipe

intended for use at low temperatures.

ASTM 333/A 333M covers several grades of carbon and alloy steel seamless and welded pipes

included Grade1, Grade3, Grade4, Grade6, Grade7, Grade8, Grade9, Grade10, Grade11.

ASTM 333/A 333M pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation. Grade 4 shall be made by the seamless process.

Note: A For each reduction of 0.01 % carbon below 0.30 %, an increase of 0.05 % manganese above 1.06 % would be permitted to a maximum of 1.35 % manganese.C By agreement between the manufacturer and the purchaser, the limit for columbium may be increased up to 0.05 % on heat analysis and 0.06 % on product analysis.
