Chemical Composition

Incoloy 800H Pipes are high-temperature nickel-iron-chromium alloy pipes designed for exceptional strength, oxidation resistance, and carburization resistance. Manufactured according to ASTM B407 Incoloy 800H seamless pipe, ASTM B514 Incoloy 800H welded pipe, and ASME SB407 UNS N08810 pipe specifications, these pipes are widely used in petrochemical plants, heat exchangers, power generation, furnaces, and chemical processing industries where long-term service above 600°C is required.

Detailed Information

Incoloy 800H Pipes Manufacturer | W.Nr. 1.4958 & DIN 1.4958 Pipe Supplier

As a leading Incoloy 800H pipe supplier, we provide premium-quality piping solutions for demanding industrial applications worldwide. Our product range includes ASTM B407 Incoloy 800H seamless pipe, ASTM B514 Incoloy 800H welded pipe, Incoloy 800H EFW pipe, and custom piping manufactured according to international standards.

Incoloy 800H is a nickel-iron-chromium alloy specifically developed for elevated temperature service. Compared to standard Alloy 800, the H grade contains controlled carbon content and optimized grain size, resulting in significantly improved creep and rupture strength.

Our inventory includes W.Nr. 1.4958 pipe, DIN 1.4958 nickel pipe, UNS N08810 nickel alloy pipe, and Incoloy 800H Schedule 40 pipe suitable for high-pressure and high-temperature systems. Every product undergoes strict quality inspection to ensure outstanding mechanical properties, dimensional accuracy, and corrosion resistance.

Whether you require small quantities or bulk industrial orders, we supply pipes in various dimensions, wall thicknesses, and end finishes to meet project specifications.
