Sumer Metal Industries Private Limited, based in Mumbai, India, is a leading manufacturer, supplier, and exporter of high-quality stainless steel products. The company specializes in precision-engineered 904L stainless steel boiler tubes, catering to diverse industrial applications. With decades of experience, the company has established a reputation for quality, timely delivery, and reliable customer support, serving clients across the globe.
Stainless Steel 904L is an austenitic stainless steel grade designed for superior corrosion resistance, particularly in acidic and chloride-containing environments. Its composition includes high nickel and molybdenum content, with added copper for better resistance to reducing acids. 904L boiler tubes are widely used in chemical processing, power generation, and pollution control equipment, ensuring high performance even under extreme conditions.
These boiler tubes conform to international standards such as ASTM A213, ASTM B677, and ASME SA213. They are available in both seamless and welded forms, with outer diameters ranging from 6 mm to 1016 mm and wall thicknesses from 0.5 mm to 50 mm. Custom lengths and finishes such as annealed, pickled, or bright annealed are available to meet client-specific requirements.
Sumer Metal Industries exports SS 904L boiler tubes worldwide, covering markets such as Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada, and regions across Africa. The company ensures compliance with international quality standards, providing seamless and welded tubes with consistent dimensions and performance reliability, earning the trust of global clients in the power and chemical sectors.

Industries such as chemical processing, power generation, pollution control, and desalination plants benefit from the exceptional corrosion resistance and high-temperature strength of SS 904L boiler tubes.
Compared to stainless steel grades like 304L and 316L, SS 904L offers superior resistance to acidic environments, especially those containing chlorides and sulfuric acid, making it ideal for harsh chemical processes and high-temperature applications.
SS 904L can be welded using standard welding techniques such as TIG and MIG. Post-weld heat treatment is recommended to relieve stresses and ensure optimal corrosion resistance, especially for critical boiler applications.
