Monel 400, also known as UNS N04400, is a high-performance nickel-copper alloy known for its outstanding resistance to corrosion in harsh environments, including seawater, acids, and alkalis. Sumer Metal Industries Private Limited is a trusted manufacturer, supplier, and exporter of Monel 400 K400 needle tubes, delivering high-quality products worldwide.
Sumer Metal Industries exports Monel 400 K400 needle tubes to Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and multiple regions across Africa. Their global distribution ensures industries in critical sectors receive reliable and durable tubing solutions for diverse applications.
The Monel 400 K400 needle tubes are manufactured according to international standards, including ASTM B165, B829, B775, B725, B163, B730, B751, and AMS 4574. Available in both seamless and welded forms, the tubes come in various dimensions, with outer diameters ranging from 6 mm to 119 mm, wall thickness from 0.25 mm to 3.0 mm, and lengths up to 6 meters or customized sizes.
The alloy is primarily composed of nickel (≥63%) and copper (28–34%), with minor additions of iron, manganese, silicon, carbon, and sulfur. This composition provides excellent resistance against corrosion, especially in marine and chemical environments, making Monel 400 K400 needle tubes highly reliable for industrial use.
