Custom Nickel-Based Alloy Powders

Nickel-based custom powders are developed for components exposed to combinations of high temperature, corrosion, oxidation, erosion and mechanical loading.

Depending on application requirements, alloy chemistry and reinforcing phases can be adjusted to improve:

• High-temperature strength
• Oxidation resistance
• Corrosion resistance
• Wear and erosion resistance
• Thermal stability
• Deposit quality and metallurgical bonding

Typical applications include turbine and energy components, valves, shafts, petrochemical equipment, oil & gas components, marine components and high-temperature industrial parts.

Alloy 625 / UNS N06625 Custom Powder

Alloy 625 is a widely used nickel-chromium-molybdenum-niobium alloy characterized by excellent corrosion resistance, good mechanical strength and strong performance in aggressive environments.

GREENSTONE can provide customized Alloy 625 powder specifications for laser cladding, DED, additive manufacturing and surface repair.

Typical applications include:

Oil & gas equipment, valves, valve seats, marine components, chemical-processing equipment, shafts, energy equipment, corrosion-resistant overlays and high-value component repair.

Custom Alloy C276 / UNS N10276 Powder

Alloy C276 is a nickel-molybdenum-chromium alloy designed for exceptionally demanding corrosive environments.

It provides strong resistance to pitting, crevice corrosion, stress-corrosion cracking and many aggressive chemical media, making it particularly valuable for chemical-processing and severe-service applications.

Customized C276 powders can be supplied for laser deposition, protective overlays, DED repair and other surface-engineering processes.

Typical industries include:

Chemical processing, petrochemical, oil & gas, pollution-control equipment, marine engineering, energy and severe-corrosion industrial systems.

Custom Cobalt-Based Composite Powders

GREENSTONE cobalt-based composite powders are intended for applications requiring combinations of:

• High-temperature wear resistance
• Hot hardness
• Corrosion resistance
• Galling resistance
• Erosion resistance
• Thermal stability

The alloy matrix and reinforcing phase can be selected according to the required wear mechanism and service temperature.

Typical applications include valves, valve seats, sealing surfaces, cutting and forming tools, energy equipment, petrochemical components and high-temperature wear parts.

Custom Iron-Based Composite Powders

Iron-based custom powders provide a cost-effective solution for industrial components requiring improved hardness, wear resistance, mechanical strength or corrosion resistance without necessarily requiring a high-alloy nickel or cobalt matrix.

Customized iron-based powders are particularly suitable for:

Mining equipment, agricultural machinery, hydraulic components, rollers, shafts, molds, gears, heavy machinery, railway components and industrial remanufacturing.

Composition and reinforcement can be optimized according to abrasion, impact, corrosion and operating-temperature requirements.

Custom Functional Composite Powders

For applications that cannot be adequately addressed by a conventional monolithic alloy, GREENSTONE can develop metal-matrix composite and blended powder systems.

Possible systems include metal matrices combined with selected carbides, ceramics or other functional phases to achieve targeted properties.

Depending on the process and application, customization can focus on:

Hardness, abrasion resistance, erosion resistance, friction behavior, thermal properties, corrosion resistance, high-temperature stability or deposition characteristics.

This makes customized composite powders particularly useful for severe-service surface engineering and repair applications.

Customized for Different Manufacturing Processes

The same nominal alloy is not necessarily optimal for every manufacturing technology. GREENSTONE therefore provides particle-size and powder-property customization according to the intended process.

Typical options include:

Laser Cladding: optimized flowability and particle-size distribution for stable coaxial or lateral powder feeding.

DED Additive Manufacturing: controlled spherical morphology and powder flow for consistent layer deposition and metallurgical quality.

Metal Additive Manufacturing: fine spherical powders with controlled particle-size distribution and low impurity levels according to the selected AM technology.

Thermal Spray: particle-size distributions optimized for coating deposition and melting behavior.

Powder Metallurgy: powder morphology and density characteristics adapted to compaction and sintering requirements.
