Monel 400 (often specified as K400 in some markets) boiler tubes supplied by Sumer Metal Industries Private Limited are high-performance nickel-copper alloy tubes engineered for demanding boiler, heat exchanger and process applications. As a manufacturer, supplier and exporter, Sumer Metal Industries emphasizes metallurgical control and tight dimensional tolerances to ensure the tubes deliver consistent corrosion resistance, long service life and weldability. The product offering targets industrial steam boilers, seawater heat exchangers, chemical process heaters and other thermal equipment where resistance to chloride stress-corrosion and impingement attack is critical.
Sumer Metal Industries exports Monel 400 / K400 boiler tubes across a wide geographic footprint including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and several regions across Africa. Export quality is backed by standard test reports (mill certificates) and optional third-party inspection. The company can supply tubes in annealed (soft) and cold-worked conditions, with customized lengths, ends (plain, beveled), and packaging options for safe overseas shipment (wooden boxes, palletizing, and protective wrapping).
Monel 400 is a nickel-copper solid-solution alloy noted for excellent resistance to seawater, steam, hydrocarbon environments and many chemical media, plus good weldability and toughness over a wide temperature range. That combination of corrosion resistance and mechanical performance makes Monel 400 tubes a preferred choice where chloride stress-corrosion cracking, acidic or reducing conditions and high flow rates are concerns. Sumer Metal Industries supplies Monel 400 tubes in annealed/cold-worked conditions depending on customer requirements and can provide traceability, NDT (where requested) and packing suitable for export.
Below is a concise technical summary of specification, chemical composition, mechanical properties and equivalent grades commonly associated with Monel 400 (K400). Typical composition and properties used for selection and procurement are shown; Sumer Metal Industries supplies material to the relevant ASTM/ASME and international tube standards on request.
