With years of expertise in the metal industry, the company has established a global presence, exporting to countries including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and multiple regions across Africa. Their focus on quality, reliability, and timely delivery has made them a trusted name in the boiler tube sector.
The Stainless Steel 304/304L Boiler Tubes offered by Sumer Metal Industries are designed to withstand extreme temperature and pressure conditions, making them ideal for industrial boilers, heat exchangers, and superheaters. These tubes are available in both seamless and welded forms, offering flexibility to meet diverse industrial applications. Their corrosion resistance, high tensile strength, and excellent thermal properties make them a preferred choice in both domestic and international markets.
These tubes are manufactured in compliance with international standards such as ASTM A213 and ASME SA213. Available in grades 304 and 304L, they come in various diameters, wall thicknesses, and lengths, with surface finishes like pickled, polished, or bright annealed. The ends can be supplied in plain, beveled, or threaded forms, depending on client requirements, ensuring they meet precise industrial standards.
The chemical composition of SS 304 and 304L Boiler Tubes ensures optimal performance. SS 304 contains 18–20% chromium, 8–10.5% nickel, and a maximum carbon content of 0.08%, while 304L has a reduced carbon content of 0.03% for enhanced weldability and resistance to carbide precipitation. The presence of manganese, phosphorus, sulfur, silicon, and nitrogen contributes to corrosion resistance, strength, and durability under high-temperature conditions.
Specification of Stainless Steel 304 / 304L Boiler Tubes
| Standard | Grades | Type | Form | Length | Surface Finish | End Finish | Application |
|---|---|---|---|---|---|---|---|
| ASTM A213 / ASME SA213 | 304, 304L | Seamless, Welded | Round, Square, Rectangular | Up to 25 meters | Pickled, Polished, Bright Annealed | Plain End, Beveled End, Threaded | Boilers, Heat Exchangers, Superheaters |
Sumer Metal Industries’ SS 304/304L Boiler Tubes exhibit excellent mechanical properties, including high tensile and yield strength, significant elongation, and good hardness. SS 304 offers a tensile strength of approximately 505 MPa and a yield strength of 215 MPa, while 304L provides slightly lower tensile and yield strengths, making it more suitable for welded applications. The modulus of elasticity of 193 GPa ensures structural stability in critical applications.
