The corrosivity of drilling mud will vary widely depending on its composition, aeration, formations being drilled, and the control of the system by the drilling contractor and mud supplier personnel. With the drilling of deeper and deviated holes, and the use of higher strength steels: higher stresses and stress reversals are applied to the drill pipe. These stresses in conjunction with corrosive environments, particularly in presence of sulfides, increases the susceptibility to stress corrosion cracking.
