SMO 254 Pipes & Tubes

Supplier & Stockist of SMO 254 Pipes & Tubes

SMO 254 Pipes & Tubes are highly specialized austenitic stainless steel products developed for extreme corrosion resistance and outstanding mechanical strength in demanding environments. Neonox Overseas, a leading supplier and exporter of premium quality stainless steel, offers SMO 254 Pipes & Tubes that comply with international standards such as ASTM, ASME, DIN, and EN. Known for its exceptional resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, SMO 254 has become the material of choice for industries exposed to aggressive environments including seawater, chemical processing, offshore oil & gas, desalination plants, and pulp & paper manufacturing.

SMO 254 Pipes & Tubes contain a high level of chromium (20%), nickel (18%), and molybdenum (6%), along with nitrogen and copper additions that provide superior strength and corrosion resistance compared to conventional stainless steels like 304 or 316. This unique composition makes SMO 254 a cost-effective alternative to nickel alloys and titanium in chloride-rich conditions. It is particularly effective in brackish water, seawater, and chloride-bearing solutions where standard stainless steels fail.

At Neonox Overseas, we supply SMO 254 Seamless Pipes, Welded Pipes, ERW Tubes, and Fabricated Tubes in a wide range of dimensions and thicknesses. Available in outer diameters ranging from 6 mm to 610 mm and wall thickness up to 50 mm, our pipes and tubes can be custom-cut to lengths up to 12 meters. These pipes and tubes are tested for durability, mechanical properties, and corrosion resistance to ensure maximum performance in harsh operating conditions.

SMO 254 Pipes & Tubes exhibit excellent weldability and formability, making them suitable for a wide variety of fabrication processes. Their high tensile strength (≥ 650 MPa) and yield strength (≥ 300 MPa) ensure structural reliability even in high-pressure and high-temperature environments. With a melting point between 1320°C and 1390°C, these pipes and tubes can withstand elevated operational conditions without losing integrity.

Industries across the globe rely on Neonox Overseas for top-grade SMO 254 Pipes & Tubes used in heat exchangers, condensers, pressure vessels, desalination equipment, offshore platforms, marine hardware, and flue-gas cleaning systems. Our strict quality standards, prompt delivery, and customer-focused solutions have established us as a trusted name in the global stainless steel market.

By choosing SMO 254 Pipes & Tubes from Neonox Overseas, customers benefit from a product that combines exceptional corrosion resistance, high mechanical strength, and long service life, making it the most reliable material solution for critical industrial applications.
