Overview
M-25S is a specialized alloy specifically formulated for exceptional resistance to both acidic and alkaline environments. This weldable grade offers excellent corrosion resistance across a wide pH range, making it suitable for challenging applications where components are exposed to harsh chemicals and corrosive solutions. Its ability to withstand both acidic and alkaline conditions makes it a valuable choice for industries such as chemical processing, wastewater treatment, and other applications where corrosion resistance in varying pH environments is critical.
Typical Uses
Filter parts, pump and valve components, seal housings.
