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.
b. Where an ellipsis "—" appears in this table, there is no requirement, and analysis for the element need not be determined or reported.
c. By agreement between the manufacturer and the purchaser, the limit for niobium may be increased up to 0.05 % on heat analysis and 0.06 % on product analysis.
d. The terms Niobium (Nb) and Columbium (Cb) are alternate names for the same element.
2. Mechanical Properties (Tensile Requirement)
The tensile test can measure three key properties of steel pipe: tensile strength, yield strength, and elongation.
| Tensile | Grade 1 | Grade 3 | Grade 4 | Grade 6 | Grade 7 | Grade 8 | Grade 9 | Grade 10 | Grade 11 |
|---|---|---|---|---|---|---|---|---|---|
| Tensile strength, min, psi [MPa] | 55,000 [380] | 65,000 [450] | 60,000 [415] | 60,000 [415] | 60,000 [415] | 100,000 [690] | 63,000 [435] | 80,000 [550] | 65,000 [450] |
| Yield strength, min, psi [MPa] | 30,000 [205] | 35,000 [240] | 35,000 [240] | 35,000 [240] | 35,000 [240] | 75,000 [515] | 46,000 [315] | 65,000 [450] | 35,000 [240] |

| ASME | JIS | EN | GB |
|---|---|---|---|
| ASME SA333 | JIS G 3460 | EN 10216-4 | GB/T 18984 |
4. Heat Treatment Requirements
All Steel Pipes Except Grade 8 and Grade 11
Select one of the following for heat treatment as needed:
- Normalize by heating to a uniform temperature of not less than 1500 °F (815 °C) and cool in the air or in the cooling chamber of an atmosphere-controlled furnace;
- Normalize by heating to a uniform temperature of not less than 1500 °F (815 °C) and at the discretion of the manufacturer, reheat to a suitable tempering temperature;
- For the seamless process only, reheat and control hot working and the temperature of the hot-finishing operation to a finishing temperature range from 1550 - 1750 °F (845 - 945°C) and cool in the air or in a controlled atmosphere furnace from an initial temperature of not less than 1550 °F (845 °C);
- For the seamless process only, reheat and control hot working and the temperature of the hot-finishing operation to a finishing temperature range from 1550 - 1750 °F (845 - 945°C), and at the discretion of the manufacturer, reheat to a suitable tempering temperature;
- Seamless pipes of Grades 1, 6, and 10 may be heat treated by heating to a uniform temperature of not less than 1500 °F (815 °C), followed by quenching in liquid and reheating to a suitable tempering temperature.
Grade 8 Steel Pipe
- Quenched and Tempered;
- Double Normalized and Tempered.
Grade 11 Steel Pipe
- When Grade 11 pipe is annealed, it shall be normalized in the range of 1400 - 1600 °F (760 - 870 °C).
