When failure isn’t an option, rely on 28 Chrome (UNS N08028) for your toughest sour service applications. This high-strength tubing excels in highly sour (H₂S) environments with moderate chlorides, delivering exceptional corrosion resistance up to 350°F. Perfect for HPHT wells, AGI applications, and critical subsurface equipment, it outperforms stainless steels with superior pitting and crevice corrosion resistance. Fully NACE MR0175/ISO15156 compliant, it’s engineered to handle 200 psi H₂S at 350°F, making it the go-to choice for high-pressure, high-temperature environments.
