Product Description

 

Product Description

 Product Introduction

 

INCOLOY® 825 (UNS N08825 / W.Nr. 2.4858), also known as NiCr21Mo and JIS NCF825, is a nickel-iron-chromium alloy alloyed with molybdenum and copper, designed to provide excellent resistance to a wide range of corrosive environments.

Alloy rings manufactured from INCOLOY 825 offer outstanding resistance to reducing and oxidizing acids, as well as good resistance to pitting, crevice corrosion, stress corrosion cracking, and intergranular corrosion.
With its balanced combination of corrosion resistance, mechanical strength, and fabrication performance, INCOLOY 825 alloy rings are widely used in chemical processing, petrochemical, oil & gas, pollution control, and marine applications.
