SMO 254 Pipes consist of around 20% chromium, 18% nickel, 6% molybdenum, 1% nitrogen, and low content of carbon, yielding superior corrosion resistance. Mechanically, they have a tensile strength of 650 MPa, yield strength of 300 MPa, and elongation of 35%, which makes them highly durable and flexible. Their physical properties are a density of 8 g/cm³, thermal conductivity of 14.5 W/m·K, and a melting range of 1320-1390°C. These characteristics render SMO 254 Pipes suitable for aggressive environments with excellent resistance against pitting, crevice corrosion, and stress corrosion cracking in challenging applications.

SMO 254 Pipes find extensive applications in industries demanding high corrosion resistance and strength. In marine conditions, they are best suited for seawater management, desalination plant applications, and offshore engineering applications because of their high resistance to corrosion from chloride attack. The chemical and petrochemical industries apply them to heat exchangers, piping systems, and pressure vessels that come into contact with severe chemicals. They are also utilized in pulp and paper treatment, food and drink manufacturing, and drug manufacturing. Also, SMO 254 Pipes find applications in power plants, flue gas treatment systems, and environmental protection systems, exhibiting long-term strength and reliability under harsh operating conditions.
SMO 254 Pipes are supplied with critical test certificates, such as Mill Test Certificates (MTC) in accordance with EN 10204 3.1, third-party inspection certificates, and material traceability reports to guarantee quality and compliance. They are properly packaged in wooden crates, waterproof wrapping, or bubble wrapping to avoid damage during transportation. With effective logistics, deliveries are timely to international markets, ensuring products are delivered to customers safely and within the specified time.
