ASTM A333 covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.
The pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.
All seamless and welded pipe shall be treated to control their microstructure by the following methods: Normalizing per A 333/A 333M-05 section 4.3.1.1; section 4.3.1.2 or section 4.3.1.3 Quenched and Tempered per A 333/A 333M – 05 section 4.3.2.1 Double Normalized and Tempered per A 333/A 333M – 05 section 4.3.2.2

| Silicon | 0.18 -0.37 | 0.10 min | |
| Nickel | 3.18 – 3.82 | ||
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. When Grade 6 is ordered under this specification, supplying an alloy grade that specifically requires the addition of any element other than those listed for the ordered grade is not permitted. However, the addition of elements required for the deoxidation of the steel is permitted.
