Alloy Grade UNS: MTEK M-152 – “400” Series Material

  • Overview

    MTEK M-152 is a high-strength, corrosion-resistant stainless-steel alloy belonging to the "400 series." This designation indicates that it possesses a higher chromium content compared to the "300 series" stainless steels, resulting in enhanced corrosion resistance and hardenability. MTEK M-152 is specifically formulated to withstand both mechanical stress and corrosive environments, making it a suitable choice for applications where components require a combination of strength and durability. This alloy's ability to resist corrosion and maintain its structural integrity makes it valuable for a variety of industries, including those involving chemical processing, marine environments, and general industrial applications.

  • Typical Uses

    Aerospace, bearings, bushings, chemical and food processing equipment, conveyor rollers, cutlery, impellers, medical devices, pump and valve components, turbine engine parts.

Frequently Asked Questions

Martensitic steel is a magnetic stainless steel that is heat-treatable and used for applications requiring high hardness.

Martensitic steel is used in chemical and food processing equipment, impellers, turbine engine components, and wear-resistant parts where hardness and strength are critical.

Austenitic steel is non-magnetic, corrosion-resistant, and ductile. Martensitic steel is magnetic, harder, heat-treatable, and more wear-resistant but less corrosion-resistant.

Martensitic steel offers high hardness, wear resistance, and strength after heat treatment, ideal for demanding mechanical applications.

Yes, martensitic steel can be heat treated through quenching and tempering to increase hardness and mechanical performance.

Yes, martensitic stainless steel is magnetic due to its body-centered tetragonal (BCT) structure after quenching.

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.
