Industry Applications

Stellite Alloy Applications Across Industries

Cobalt-based Stellite alloys deliver exceptional performance in the most demanding industrial environments -- from extreme heat and pressure to aggressive corrosion and continuous wear.

Oil & Gas

High Priority Industry

Stellite alloys are widely used in valves, pumps, and downhole tools operating under extreme pressure, corrosive media, and high temperatures in oil and gas extraction and processing.

  • Gate valve seats & trim components
  • Ball valve seats & seal rings
  • Pump impellers & wear rings
  • Choke & control valve internals

Power Generation

Thermal & Nuclear

In steam turbines, nuclear reactors, and thermal power plants, Stellite components resist high-temperature oxidation, erosion, and metal-to-metal wear under continuous operation.

  • Steam turbine blade tips
  • Valve seats & spindles
  • Nuclear reactor valve components
  • Boiler feed pump wear parts

Industrial Valves & Pumps

Core Application

Valve seats, stems, and pump internals hardfaced or manufactured from Stellite alloys achieve superior sealing performance and extended service life in corrosive or abrasive fluid systems.

  • Globe & gate valve seats
  • Valve stems & plug components
  • Pump shaft sleeves & bushings
  • Mechanical seal faces

Steel & Metal Processing

High-Wear Environment

Steel mills and metal processing facilities rely on Stellite-tipped and Stellite-coated tooling to withstand intense abrasion, impact, and elevated temperatures during continuous production.

  • Saw tips & circular saw blades
  • Scraper blades & wear plates
  • Roll guides & side guides
  • Shear blades & cutting tools

Plastic & Rubber Machinery

Extrusion & Molding

Extrusion dies, screw tips, and barrel liners made with Stellite alloys resist wear from abrasive polymer compounds and corrosion from chemical additives, significantly extending equipment life.

  • Extrusion dies & die lips
  • Screw tips & check rings
  • Barrel & screw wear segments
  • Mixer blades & rotor tips

Mining & Aggregate

Extreme Abrasion

Mining equipment faces severe abrasion and impact. Stellite-hardfaced components and wear inserts dramatically extend service intervals and reduce unplanned shutdowns in crushing and drilling operations.

  • Drill bit inserts & wear pads
  • Crusher wear liners
  • Slurry pump components
  • Conveyor & chute wear parts

Chemical & Petrochemical

Corrosion Resistance

Chemical processing environments demand materials that resist both corrosion and wear simultaneously. Stellite alloys maintain dimensional stability and surface integrity in aggressive chemical media.

  • Agitator shaft sleeves & seals
  • Reactor valve internals
  • Pump casings & impellers
  • Spray nozzles & orifice plates

Food & Pharmaceutical

Hygienic Processing

In food processing and pharmaceutical manufacturing, Stellite components provide corrosion resistance to cleaning agents and product media while maintaining surface finish and dimensional accuracy.

  • Homogenizer valve seats
  • Cutting & slicing blade edges
  • Pump seal rings & bushings
  • Tablet press tooling components

Aerospace & Defense

High-Temperature Alloys

Aerospace and defense applications demand exceptional strength at elevated temperatures. Stellite alloys are used in turbine components and structural wear parts that must perform reliably under extreme thermal cycling.

  • Gas turbine vane & nozzle segments
  • Bearing races & bushings
  • Fuel control valve components
  • Actuator wear pads & inserts
