High-wear Rare Earth Alloy Flange For Harsh Industrial
Zg40cr8mnmonisire flange offers outstanding wear, corrosion, and impact resistance, ideal for abrasive, high-temperature, and high-pressure pipeline systems.
The ZG40Cr8MnMoNiSiRe Flange is a high-performance flange fitting made from a specialized rare earth alloy steel, engineered for extreme durability in abrasive, corrosive, and high-impact environments. Its alloy composition includes chromium (Cr), manganese (Mn), molybdenum (Mo), nickel (Ni), silicon (Si), and rare earth elements (Re) such as cerium and lanthanum, providing exceptional structural integrity and surface hardness.
Thanks to rare earth modification, the steel achieves a refined microstructure, improved carbide distribution, and reduced grain boundary brittleness. The result is a flange that withstands heavy mechanical stress, thermal shock, and aggressive media—making it perfect for connecting pipes in slurry systems, ash lines, or high-wear industrial pipelines.
Typical hardness ranges from 240 to 320 HB, with excellent tensile strength, crack resistance, and long service life. It is compatible with both ANSI and DIN standards, and available in flat face, raised face, or custom flange designs (slip-on, weld neck, blind, threaded, etc.).
Also known as rare earth alloy wear resistant flange, ZG40Cr alloy flange, or abrasion resistant steel pipe flange, this product reduces flange failure risks in critical connections.

There are six most commonly used flanges, also knows as ANSI Flange, ASME B16.5 Flange. However, these designs can be modified to meet the specific functions and requirements of the applications. Therefore, it’s essential to understand the pressure at the flagged joint, the required strength, and the size of pipes involved. With the correct information comes six types of flanges that an individual can choose from. These include:
ZG40CrMnMoNiSiRe alloy is ideal for high-strength, wear-resistant, and impact-tolerant components across demanding industries.
