UNS N08825 - EN/DIN 2.4858 – NiCr21Mo

UNS N08825 is a Nickel Iron Chromium Alloy with Molybdenum and Copper. With an excellent resistance to reducing and oxidising acids it is also especially resistant to sulphuric and phosphoric acids. Due to this characteristics it often used for applications such as waste treatment and in the pulp and paper industry.

As one of the worldwide biggest manufacturer and stockist of UNS N08825 we supply this Material to many different industries such as oil and gas, power generation, petrochemical and other industries.

TPS Technitube Roehrenwerke GmbH supplies UNS N08825 in a big variety of forms incl.:
