Alloy Grade UNS: MTEK MA-1 – High Temp Strength

  • Overview

    MTEK MA-1 is a proprietary high-temperature alloy specifically engineered to deliver exceptional performance in demanding environments. This alloy exhibits excellent high-temperature strength, maintaining its structural integrity and resisting deformation even under prolonged exposure to extreme heat. Furthermore, MTEK MA-1 offers outstanding carburization resistance, preventing the absorption of carbon and subsequent embrittlement in carbon-rich atmospheres. With a service limit of 2155 degrees Fahrenheit (1180 degrees Celsius), MTEK MA-1 is well-suited for challenging applications in industries where components must operate reliably under extreme thermal conditions.

Minimum Mechanical Properties

Frequently Asked Questions

Heat resistant stainless steel refers to alloys designed to maintain mechanical properties and resist oxidation at elevated temperatures.

Applications include furnace parts, heat exchangers, and components in petrochemical plants.

Heat resistant stainless steels can withstand temperatures up to 1,150°C (2,100°F), depending on the grade and exposure time.

High chromium and nickel contents stabilize the austenitic structure and form a protective oxide layer, resisting scale and oxidation.

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.
