Features of ASTM A333 Grade 6 Carbon and Alloy Steel Pipes

• ASTM A333 specification covers both seamless hot-finished and seamless cold-finished treatment.
• 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
• This specification covers several grades of carbon and alloy steel seamless and welded pipes. When welding is used for joining the weldable mechanical tube grades, the welding procedure shall be suitable for the grade, the condition of the components, and the intended service.
• The pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.
• Heat Treatment – Product is supplied in the normalized, 1500 f and air cooled, condition. It may be quenched and tempered by heating to 1475 F, quench in circulating water and then temper by re-heating to 1100 F and rapid air cooling.
• Hot Working – Hot working may be done qt 2000 F down to 1600 F if need be. Do not hot work below 1550 F and immediately following hot working cool in a controlled atmosphere furnace from a temperature above 1550 F.
• Cold Working – Cold working may be done by conventional methods.
• Annealing – Anneal, or normalize, at 1600 F and air cool.
• Forging – Product is supplied in pipe form and not normally forged from that shape.
• Flattening Test – One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot.
• Flaring Test – One flaring test shall be made on specimens from each end of one finished tube, not the one used for the flattening test, from each lot.
• Hydrostatic or Nondestructive Electric Test – Each tube shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.
• Surface and Dimension Test
• Tensile Strength, Yield Strength, Elongation, Bending, Hardness, Impact Test.
• Chemical Composition Inspection
