Alloy Grade UNS: CL III TYPE A – Wear Resistant Alloy

  • Overview

    CL III Type A is a wear-resistant white iron alloy that distinguishes itself through its hardness and ability to withstand demanding conditions. Containing approximately 3% chromium, this alloy offers enhanced oxidation resistance, making it suitable for high-temperature applications. Its inherent hardness provides exceptional resistance to wear, abrasion, and erosion, ensuring long-lasting performance in environments involving friction, sliding contact, and impact. CL III Type A is a valuable choice for components requiring durability and dimensional stability under 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.
