Largest SMO 254 Buttweld Fittings Supplier in Chennai, India

SMO 254 Buttweld Fittings consist of around 20% of chromium, 18% of nickel, 6% of molybdenum, and 0.2% of nitrogen. This alloy has a high Pitting Resistance Equivalent Number (PREN > 42.5), thus making the alloy highly resistant to localized attack in seawater and hostile chemical environments. The fittings have outstanding mechanical properties with a tensile strength of approximately 650 MPa and yield strength of 300 MPa. The nitrogen content improves strength and structural stability, while minimal carbon content prevents intergranular corrosion, particularly after welding.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
