介绍 | SCF-19® alloy is an austenitic, nitrogen-strengthened stainless steel. Because of its combination of stress-corrosion-cracking resistance, high strength, and low magnetic permeability it has been used as a nonmagnetic drill collar and MWD housing alloy. Laboratory and field evaluations have shown its superiority over the conventional chromium-manganese stainlesses commonly used for such applications. The strength of SCF-19 alloy is achieved by warm working on a rotary forge at a temperature below the recrystallization temperature. SCF-19 alloy has been used for the following oil and gas well drilling components: Drill collars Stabilizers MWD housings |
