• Fixed-plant maintenance groups

Our application ensures you get the right alloy for extreme conditions, the appropriate deposition method, and the right service life for your specific operating environment.

Applications in Mining & Heavy Industry

Special alloys are used to repair or enhance components in harsh environments. 

UTP Maintenance alloys are used on:

• Sour-service valves, Inconel repair

• Add-leaching tanks, tailing lines

• Chloride & fluoride processing

• Smelter kiln & furnace repairs

• Valve seats, hot shear blades

• Sour-service pump trim

• Furnace components, petrochemical

• Any alloy exposed to high heat/corrosion

Typical Special Alloy Problems

Common challenges in mining and heavy industry include:

• Pitting/crevice corrosion in acids/chlorides

• Oxidation/galling at high temperatures

• Cracking in dissimilar high-alloy joins

• Short service life in sour/alkaline media

• Difficulty welding without distortion/dilution

UTP alloys address these with tailored carbide content and compositions—now enhanced with 2025 Cr-reduced formulas for fume safety.

Understanding Special Alloy Modes

Common challenges in mining and heavy industry include:

• Nickel-base – for pitting/crevice corrosion resistance in acids/chlorides

• Cobalt-base – for wear + corrosion at high temperatures

• High-temperature – for oxidation/galling resistance up to 1100°C

Each mode requires specific alloys – which UTP provides for optimal performance.
