What Deloro Stellite does

Deloro Wear Solutions GmbH, formerly Deloro Stellite GmbH, is a privately held German specialty metallurgy manufacturer headquartered in Koblenz, Rhineland-Palatinate, founded in 1910 and operating under the Deloro Group alongside two wholly-owned Italian subsidiaries, Deloro Coatings S.r.l. (Bellusco) and Deloro Microfusione S.r.l. (Pieve Emanuele). The company develops and manufactures wear-resistant alloys (cobalt-chromium Stellite and Tribaloy families, nickel-based Nistelle, iron-based Delcrome, and proprietary Ultimet), thermal-spray and weld-overlay coating services (HVOF, plasma spray, PTA, laser cladding), PTA welding equipment, and ready-to-install engineered components produced through investment casting, sand casting, centrifugal casting, and powder metallurgy. Its technology portfolio includes registered alloy trademarks developed over 115 years and emerging additive manufacturing capabilities for cobalt-based alloys developed in partnership with Fraunhofer IFAM and DMRC at the University of Paderborn.

The company operates an enterprise B2B go-to-market targeting engineering-intensive industrial customers across oil and gas, power generation, aerospace, mining, chemical processing, automotive, hydropower, food processing, and general mechanical engineering. It sells directly through technical field sales augmented by application engineering support, with international distribution partners extending reach for consumables. Pricing is quote-based with multi-year contracts, and the company supports customers from material selection and wear analysis through prototyping, coating services, and post-installation lifecycle support. Named customers include Siemens Energy, Welland Power and Energy, Klinger Westad, Ekato, Probat, and KWO, among 2,295+ active accounts globally.

The business holds a diversified portfolio of quality certifications supporting regulated verticals, including ISO 9001:2015, ISO 13485 (medical devices), ISO 19443 (nuclear), AD 2000 / EN 764-5 (pressure equipment), ISO 3834 (welding quality), and NADCAP and AS9100 for the Italian Microfusione subsidiary. Leadership is stable with long tenure: CEO Michael Rünz has been with the company for over 30 years, and the management team includes dedicated directors for R&D and quality, welding equipment and materials, organizational development, and operations. Revenue, ownership structure, and headcount beyond the approximately 300-employee Koblenz site are not publicly disclosed.

Core offering

Deloro manufactures and supplies integrated wear-protection solutions for industrial components operating under extreme wear, corrosion, and high-temperature conditions. Its portfolio spans proprietary wear-resistant alloys (cobalt-, nickel-, and iron-based consumables in powder, wire, and rod form), ready-to-install cast and machined components (valve, pump, screw conveyor, turbine parts), Plasma Transferred Arc (PTA) welding systems manufactured in Germany, and industrial coating services using HVOF, plasma spraying, PTA, TIG, MIG, and laser cladding.

Product overview

Deloro Stellite (Deloro Wear Solutions GmbH) operates as a single-source supplier offering an integrated portfolio of wear protection solutions. The core offering consists of three interconnected product lines: (1) PTA Welding Systems — proprietary Plasma Transferred Arc equipment manufactured in Germany, Internet-of-Things-ready with intuitive interfaces; (2) Consumables — welding powders, wires, and rods based on cobalt, nickel, and iron alloys; and (3) Engineered Components — ready-to-install precision components manufactured using sand casting, investment casting, centrifugal casting, and powder metallurgy. The materials portfolio includes proprietary sub-brands such as Stellite® (cobalt-chromium alloys), Tribaloy™ (cobalt-Laves phase alloys), Nistelle (nickel-based), Delcrome (iron-based), Deloro alloys, and Ultimet®. Engineering services (wear analysis, material selection, prototyping) and coating services (HVOF, plasma spray, laser cladding) complement the product range. The company controls the full value chain from material development through finished components, positioning itself as a one-stop supplier for industrial wear protection. Deloro Group includes two Italian subsidiaries: Deloro Coatings S.r.l. (thermal coating services) and Deloro Microfusione S.r.l. (investment casting of superalloys).

Broad incumbents

• Kennametal: Global manufacturer of tungsten carbide, wear-resistant tooling, and engineered components serving mining, oil & gas, aerospace, and power generation. Directly comparable to Deloro in the wear-parts business and significantly larger, offering an overlapping product portfolio across materials, components, and surface solutions.
• Carpenter Technology: US specialty alloys producer with broad nickel, cobalt, and stainless portfolios serving aerospace, medical, and energy. Overlaps with Deloro on high-performance alloy supply and offers broader scale but does not focus on dedicated wear-protection components or coating services.
• Metso: Global supplier of mining and aggregates processing equipment, including wear parts and crusher liners. Compares to Deloro's wear-components business particularly in the mining vertical, though Metso is far larger and focuses on OEM equipment rather than specialty alloys.
• Praxair Surface Technologies (Linde): Surface coatings and thermal spray services business within Linde, applying wear- and corrosion-resistant coatings (HVOF, plasma, wire arc) to aerospace and industrial components. Direct competitor to Deloro Coatings in the contract coating service market.

Direct peers

• Oerlikon Metco: Surface solutions division of Oerlikon offering thermal spray equipment, coating materials (powders and wires), and coating services for wear, corrosion, and thermal protection. The closest direct competitor to Deloro's consumables, PTA systems, and thermal spray service offering across aerospace, power, and industrial markets.
• Wall Colmonoy: Manufacturer of Colmonoy nickel- and cobalt-based wear-resistant alloys, fused-alloy coatings, and engineered components for aerospace, oil & gas, and industrial markets. Closely comparable to Deloro in proprietary cobalt/nickel alloy portfolios, hardfacing consumables, and engineered wear components.
• Bodycote: World's largest thermal processing services provider, including specialist coatings (HVOF, plasma, weld overlay) for wear and corrosion protection. Overlaps with Deloro Coatings' service offering and competes for the same aerospace, energy, and industrial customer base.
• Haynes International: Producer of high-performance nickel- and cobalt-based alloys (e.g., Hastelloy, Haynes alloys) for severe-service corrosion and high-temperature applications. Direct comparability with Deloro's Nistelle and Stellite product families in aerospace, chemical, and power generation end-markets.
• Castolin Eutectic: Specialist in wear-protection solutions including welding consumables, thermal spray equipment, and coating services under the Eutectic and Castolin brands. Competes head-to-head with Deloro in hardfacing consumables and PTA/weld-overlay coating services across industrial verticals.

Regional players

• FLSmidth: Danish-headquartered supplier of mining and cement processing equipment, including abrasion-resistant wear parts. Comparable to Deloro's mining and heavy-industry wear-components offering, with stronger presence in cement and minerals processing than Deloro.
