介绍 | SCF 19® Max alloy is an austenitic, nitrogen-strengthened stainless steel containing 5% Mo for improved stress-corrosion-cracking resistance. The alloy can be warm worked to achieve a minimum yield strength of 140 ksi. Because of its combination of stress-corrosion-cracking resistance, chloride pitting resistance, high strength, and low magnetic permeability it has been used as a nonmagnetic drill collar and MWD/LWD housing alloy in some of the harshest drilling environments. Laboratory and field evaluations have shown its superiority over the conventional chromium-manganese stainlesses commonly used for such applications. SCF 19 Max has been used for the following oil and gas well drilling components:
