Alloy Grade UNS: 9B – General Structure Alloy

  • Overview

    9B is a general structure alloy. It has good castability, machinability, and weldability. It is a low-carbon steel, that also has silicon and manganese. Also known as MTEK WCB, it offers excellent wear resistance, good strength, and ductility.

  • Typical Uses

    Cylinders, marine propulsion, rolls, shaft sleeves.

  • MetalTek Grade

    WCB

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%.

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.
