Pathan Durgadevi Udyan, Ground Floor, 25 Plot No 74/80, Patra Chawl, Maruti , Mandir Marg, Second Street, Girgaon, Mumbai, Maharashtra 400004Tubotech Alloys is a leading manufacturer, supplier, and exporter of premium quality SMO 254 Instrumentation Fittings in Germany. Our SMO 254 fittings are manufactured using high-alloy austenitic stainless steel UNS S31254 / EN 1.4547, offering exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. These fittings are widely used in chemical processing, offshore industries, marine applications, desalination plants, power generation facilities, and instrumentation systems requiring superior corrosion resistance.
SMO 254 is a super austenitic stainless steel alloy containing high levels of chromium, molybdenum, and nitrogen, making it ideal for highly aggressive chloride environments and seawater applications. The alloy provides nearly twice the strength of conventional 300 series stainless steels while maintaining excellent weldability and fabrication characteristics.
Tubotech Alloys offers a comprehensive range of SMO 254 Instrumentation Fittings, including:
Our fittings are manufactured in accordance with international standards and are available in customized dimensions to meet specific project requirements.
| Element | Composition (%) |
|---|---|
| Carbon (C) | ≤ 0.02 |
| Silicon (Si) | ≤ 0.80 |
| Manganese (Mn) | ≤ 1.00 |
| Phosphorus (P) | ≤ 0.03 |
| Sulfur (S) | ≤ 0.01 |
| Chromium (Cr) | 19.5 – 20.5 |
| Nickel (Ni) | 17.5 – 18.5 |
| Molybdenum (Mo) | 6.0 – 6.5 |
| Nitrogen (N) | 0.18 – 0.22 |
| Copper (Cu) | 0.5 – 1.0 |
The high chromium, molybdenum, and nitrogen content significantly enhance corrosion resistance and provide an excellent PREN value above 42, making SMO 254 suitable for severe chloride-bearing environments.
