SCF 19® Max 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.
