Sumer Metal Industries Private Limited manufactures premium Super Duplex Steel S32750 (Alloy 2507 / UNS S32750) boiler tubes engineered for the most demanding pressure-vessel and heat-exchange applications. These tubes combine a two-phase (ferrite + austenite) microstructure that gives exceptionally high strength and superior resistance to chloride stress-corrosion cracking, pitting and crevice corrosion compared with conventional austenitic stainless steels — making them ideal for aggressive environments in oil & gas, desalination, offshore, chemical and power plants.
As a manufacturer, Sumer Metal Industries produces S32750 tubes in solution-annealed and finish-tested condition using controlled melting, nitrogen control and precision hot-working to maintain the correct microstructure and PRE (pitting resistance equivalent). Their quality program includes PMI/chemical analysis, hydrostatic/eddy-current testing and surface finishing options to meet both standard and bespoke customer requirements destined for international projects.
Sumer Metal acts as supplier and exporter to markets including Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada and multiple regions across Africa — providing export documentation, material traceability, packing for seaworthy shipment and customer support for customs and project logistics. For project buyers the company offers material certificates (EN/ASTM), NDT reports, and if required, heat-treatment records and third-party inspection. (Logistics and export services follow standard international trade practice.)
Typical specifications for S32750 boiler tubes supplied by Sumer Metal Industries include material designation UNS S32750 / Alloy 2507, EN designation X2CrNiMoN25-7-4 (1.4410), heat-treated (solution annealed) condition, standard sizes (OD and wall thickness per client), and common standards such as ASTM A789 / A790 / A240 where applicable for tube and plate forms. The tubes are supplied with mill test certificates and are compatible with common welding and fabrication practices when appropriate filler metals and procedures are used.
Specification of Super Duplex Steel S32750 Boiler Tubes
| Property | Value / Note |
|---|---|
| Material designation | UNS S32750 (Alloy 2507, Super Duplex) |
| EN designation | X2CrNiMoN25-7-4 (1.4410) |
| Common Standards | ASTM A789 / A790 (tubes), ASTM A240 (plate), EN standards as requested |
| Condition | Solution annealed and rapid cooled; annealed condition unless otherwise specified |
| Typical Uses | High-pressure heat exchangers, boilers in chloride environments, seawater equipment, oil & gas and chemical plants |
| Certificates | Mill test certificate (MTC / EN 10204 3.1), PMI report, NDT reports (as required) |
The chemical composition of S32750 emphasizes high chromium (≈24–26%), molybdenum (≈3.0–5.0%) and nitrogen (≈0.24–0.32%) plus moderate nickel (≈6–8%) — this alloy chemistry yields a combination of very high strength and excellent localized corrosion resistance. The material’s mechanical properties in the annealed condition commonly specify a minimum ultimate tensile strength ≈ 795–800 MPa (≈116 ksi) and 0.2% offset yield strength ≈ 550 MPa (≈80 ksi), with elongation typically ≥15% depending on form and test method.
