Alloy Grade UNS: CH13 – Abrasion Resistance

  • Overview

    CH13 is a non-deforming alloy specifically engineered to provide exceptional wear and abrasion resistance. This alloy maintains its dimensional stability even under demanding conditions involving friction, sliding contact, and repetitive stress. Its ability to resist wear and abrasion makes it a valuable choice for applications where components are subjected to harsh environments and require long-term dimensional accuracy. CH13's inherent stability ensures that it retains its shape and dimensions over time, making it a preferred choice for applications demanding durability and precision.

Frequently Asked Questions

Tool steel alloys are high carbon chrome steels containing molybdenum, cobalt and/or vanadium. Certain tool steels are engineered to withstand repeated high loads and impacts at ambient temperature with exceptional wear resistance.

Used in cutting tools, dies, molds, drills, punches, and industrial machinery components requiring wear and impact resistance.

Major types include water-hardening, cold-work, shock-resistant, high-speed, and hot-work tool steels.

Tool steel is hardened using heat treatment: heating to a specific temperature, quenching, and tempering to achieve desired hardness and toughness.

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.
