Alloy Grade UNS: CL II TYPE B – Wear Resistant Alloy

  • Overview

    CL II Type B, also known as MTEK HC-225, is a wear-resistant alloy engineered for exceptional durability in demanding environments. This alloy is characterized by its good hardness and excellent oxidation resistance, making it suitable for applications involving high temperatures and abrasive wear. Its composition, which includes a maximum of 2.5% nickel along with low carbon and manganese content, contributes to its ability to withstand wear, friction, and elevated temperatures. CL II Type B is a valuable choice for components requiring long-term performance and resistance to wear in challenging conditions.
