Alloy Grade UNS: MTEK 535 – Martensitic Alloy

  • Overview

    MTEK 535 is a martensitic stainless-steel alloy known for its high strength, hardness, and good corrosion resistance. This type of alloy is characterized by its ability to be hardened through heat treatment, resulting in increased strength and wear resistance. MTEK 535's martensitic microstructure provides a good balance of toughness and hardness, making it suitable for applications requiring both impact resistance and wear resistance. This alloy is often used in demanding environments where components are subjected to high stresses and potential wear and tear.

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.
