ASTM B165 Monel 400 seamless pipe maintains excellent mechanical strength and corrosion resistance across a wide temperature range - from cryogenic conditions down to –196°C up to service temperatures of 482°C. Its exceptional resistance to hydrofluoric acid (HF), seawater, and reducing acids makes it the material of choice for oil refining, marine, and chemical processing applications.
Huitong supplies Monel 400 pipe in both seamless (cold-drawn and hot-finished) and welded configurations, manufactured to ASTM B165 and ASME SB165 standards, with full material traceability and third-party inspection available. Contact us to get free quote and sample!
