The SMO 254 tubing possesses about 20% chromium, 18% nickel, 6% molybdenum, and nitrogen (0.18–0.22%), which gives an exceedingly high pitting resistance equivalent number (PREN >42.5). It possesses a tensile strength of ≥650 MPa and yield strength of ≥300 MPa, with elongation (~35%) being good. The addition of nitrogen adds strength and enhances localized corrosion resistance. SMO 254 tubes maintain their integrity in high-pressure–high-temperature applications. The synergy of mechanical performance and resistance to corrosion makes it one of the most trustworthy tubing materials for extreme and chloride-rich environments.

Our products are widely used in various applications, and we are committed to delivering excellent service, resulting in high customer satisfaction. Our unique finishing techniques further distinguish us in the stainless steel industry. We are dedicated to consistently providing superior products and effectively meeting our customer’s needs.
SMO 254 tubing is used in critical applications where applications are in chloride-rich and highly corrosive environments. Applications are common in heat exchangers, condensers, chemical process lines, marine fittings, offshore installations, and seawater systems for cooling. It is also found to be used extensively in flue gas desulfurization equipment, pulp and paper bleaching plant equipment, and desalination plants. Due to the good resistance against pitting and crevice corrosion, it can be used for carrying aggressive media under high pressure. Its fine weldability and toughness render SMO 254 tube the industry’s first choice in sectors that require long service life, low maintenance, and high corrosion resistance.
