T22 alloy steel pipe mechanical properties :
| Tensile strength MPa | Yield point Mpa | Elongation% | Impact power J |
| ≥415 | 205 | See table |
T22 alloy steel pipe process:
Hot-rolled (extrusion seamless steel tube): round tube blank heated perforated three-roller oblique rolling, continuous rolling or extrusion decollation sizing (or reducing) cooling blank tube straightening hydraulic pressure test (or flaw detection) mark storage.
Cold-drawn (rolled) seamless steel tubes: round tube blanks, heated piercing, head annealing, pickling, and oil coating (copper plating), multi-pass cold drawing (cold-rolling), billet, heat treatment, straightening, hydrostatic testing (flaw detection), marking, storage.
