Andre Stainless stands out as a reliable manufacturer and supplier of top-notch SMO 254 Forged Fittings in Singapore, Pulau Ujong. They provide high-performance solutions tailored for the toughest industrial environments. SMO 254 is a high-alloy austenitic stainless steel known for its remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. These forged fittings come in various shapes, including elbows, tees, couplings, unions, and reducers, making them perfect for critical applications in sectors like offshore oil & gas, desalination, marine, and chemical processing. Adhering to ASTM A182 standards, Andre Stainless guarantees tight tolerances, impressive strength, and dependable corrosion resistance with every product they deliver.
SMO 254 Forged Fittings are made up of roughly 20% chromium, 18% nickel, 6% molybdenum, and 0.2% nitrogen, achieving a Pitting Resistance Equivalent Number (PREN) of over 42.5. This unique composition ensures outstanding corrosion resistance in seawater, acidic solutions, and environments rich in chlorides. On the mechanical side, these fittings boast a tensile strength of around 650 MPa, a yield strength of about 300 MPa, and an elongation of roughly 35%. The alloy is known for its excellent impact toughness and maintains its strength even at high temperatures. Plus, SMO 254 is non-magnetic and fully austenitic, making it perfect for both cryogenic and high-temperature applications in demanding industrial settings.

These fittings are available in sizes from 1/8″ to 4″ and offer reliable, leak-free connections in high-pressure systems. They are commonly used in petrochemical, power generation, and oil and gas industries.
Threaded fittings, ranging from 1/8″ to 4″, provide ease of installation and maintenance. Suitable for low-pressure applications, they are widely used in plumbing, heating, and cooling systems.
These elbows, available in sizes from 1/8″ to 4″, allow for smooth directional flow changes. They are ideal for piping systems requiring high-strength connections and reduced flow resistance.
Threaded tees, in sizes ranging from 1/8″ to 4″, branch off the main line in a piping system. They provide reliable performance in various industrial and commercial applications.
These couplings, available in sizes from 1/8″ to 4″, join two pipes or fittings. They offer easy assembly and disassembly, making them suitable for maintenance and repair work.
Socket weld crosses, ranging from 1/8″ to 4″, are designed to connect four pipes at a single junction. They are used in high-pressure applications where a strong, leak-proof connection is essential.
SMO 254 Forged Fittings find their place in highly corrosive and high-pressure systems across various industries, including oil & gas, marine engineering, petrochemicals, desalination, pulp & paper, and chemical processing. Their exceptional resistance to chloride-induced corrosion makes them ideal for seawater cooling systems, brine lines, heat exchangers, pressure vessels, and offshore platforms. You’ll also find these fittings in flue gas desulfurization units and food-grade chemical systems. With their high mechanical strength and reliability, they are a go-to choice for many
