Alloy Steel

What Alloy Steel does

Alloy Steel International (ASI) is a vertically integrated Australian manufacturer of wear-resistant products for the global mining and resources industry, founded in 1991 by the late Gene Kostecki and now led by his son Steven Kostecki as Managing Director and CEO. From a 5,000 sqm facility in Malaga, Perth, Western Australia, ASI produces a portfolio including Arcoplate fused chromium carbide overlay plate, Arcotuff ceramic wear liners (92% and 95% Alumina, ZTA, and SiC variants), Arcoblock cast high wear products, Arcobolt single-sided fastening systems, and Arcoweld welding consumables, complemented by WAM, an IIoT-based predictive maintenance system with IP68 wireless probes, long-range gateways, and cloud-based analytics. The company holds Stage 2 ISO9001, ISO45001, ISO14001, and ISO31000 certifications and operates patented production processes including Arcobolt (Patent No. 2017101562).

ASI generates revenue primarily through one-time product sales of proprietary wear products and project-based engineering, fabrication, and off-site refurbishment services, with pricing negotiated per project rather than publicly disclosed. Go-to-market is enterprise field sales targeting large multinational mining corporations and mid-size public and private operators, supplemented by qualified distributor and representative networks across 25+ countries with regional offices in Spring Branch, Texas (North America) and Jamshedpur, India. Customer segments are concentrated in mining and bulk material handling applications including conveyors, stackers, reclaimers, train load outs, ship loaders, chutes, hoppers, and crushers.

In February 2026, ASI was acquired by Lincoln Electric Holdings Inc as part of the parent's RISE strategic expansion of welding and mobile work solutions capabilities, integrating ASI's wear products and Australian manufacturing base into a global welding platform.

Revenue model

1. Wear Products Sales (Arcoplate, Arcotuff, Arcoblock, Arcobolt): Sale of proprietary wear-resistant products including Arcoplate fused alloy steel plate, Arcotuff ceramic liners, Arcoblock cast products, Arcobolt fastening systems, and Arcoweld welding consumables. Products are sold as standard stock or customized to specific customer requirements. Revenue is primarily one-time product sales, with repeat orders driven by product wear cycles in mining operations.
2. Engineering and Fabrication Services: In-house engineering services including design/drafting, materials handling, project management, DEM (Discrete Element Modeling), 3D laser scanning, fabrication, welding, NDT, surface treatment, liner installation, and quality control. Services are provided alongside product sales to deliver complete wear solutions. Revenue is project-based and service-oriented.
3. Off-site Repairs and Refurbishment: Off-site repair and refurbishment services for customer assets including hopper chutes and train load out systems. Includes detailed strip and assess, scope of works, transport frames, scan data, wear reports, NDT, blast and paint, chute assembly, improvements, short head tram, and liner installation. Revenue is project-based per job.

• Sandvik Mining and Rock Solutions: Swedish major mining equipment OEM with broad equipment and spare parts portfolio including wear consumables. A larger incumbent operating across mining, while ASI is specialised in wear consumables and services.
• FLSmidth: Danish supplier of mining and cement equipment with a broader process-equipment portfolio. Comparable end markets and wear consumables, but operates as a generalist process-equipment OEM rather than a wear-specialist niche player.

Direct peers

• Bradken: Australian mining-focused manufacturer of wear-resistant components, liners, and casting products. Directly comparable geographic base and mining customer overlap with Arcoplate and Arcoblock product lines.
• Kennametal: US producer of wear-resistant components, cutting tools and materials for mining, construction and industrial markets. Comparable advanced metallurgy and wear products serving similar mining and heavy industrial customers.
