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.

  • Typical Uses

Frequently Asked Questions

Abrasion resistant cast iron is a high-hardness iron alloy designed to resist wear and friction from repetitive contact or movement.

Used in mining equipment, cement mixers, chute liners, pumps, and earthmoving machinery due to superior wear resistance.

Its high carbon and alloy content forms carbides and pearlite/martensite structures, enhancing surface hardness and wear resistance.

Non-Ferrous

Non-ferrous alloys are, literally, materials that are not iron-based. While others may provide non-ferrous materials of other materials, the MetalTek family of non-ferrous alloys are copper-based. In general, these materials deliver high strength, and excellent wear and corrosion resistance. They are often found in marine applications and also bushing, bearing, and gear environments.
Stainless Steel Parts

Stainless Steel

Stainless steels owe their ability to resist corrosion primarily to the presence of a passive film on their surface. Chromium is chiefly responsible for formation of the passive film. Iron ceases to rust at approximately 12% chromium content and resistance to oxidizing corrosives increases rapidly with chromium content up to approximately 20%.
Petrochemical Fittings

Specialty Alloys

Specialty Alloys comprise a broad group of materials that deliver properties for more demanding applications, use more exotic or expensive materials, or require special processes to manufacture. Where standard materials may not offer desired performance, specialty alloys (including those that are modified further) may be a sensible selection.
