Arcoplate Manufacturer & US Inventory:

  • Manufacturer: Alloy Steel International (ASI) in Perth, Australia
  • Artha WearTech: US inventory based in San Antonio, TX, and Phoenix, AZ
Alloy Steel International has been manufacturing the Arcoplate family of products for over 30 years, securing a strong global presence in over 25 countries. Renowned companies like Rio Tinto, BHP, and OEMs such as Caterpillar and Komatsu trust ASI’s wear solutions.
In 2023, Artha WearTech was appointed as the official ASI Partner for the USA and Canada, following a longstanding relationship between ASI’s India Country Manager and our President. Our first major order came from a leading iron ore mining company in Quebec, totaling $500,000 for Arcoplate products deployed in Fixed Plant applications, including the Surge Bin and Primary and Secondary Hoppers. Our Proposals help them evade 4-liner replacement downtime cycles on each component and save the company from investing in liners for 2-liner replacement cycles.
As a company, we are focused on advancing our presence in the mining industry, particularly in iron ore, gold, and copper. With over 30 years of experience selling mining solutions across the US, Canada, Panama, Colombia, India, and Australia, we are well-positioned to serve clients from our base in Phoenix, Arizona. Our immediate focus is on the Western US, with sub-distributors strategically located in the Midwest, East, and Southeast, including Florida.

WHAT IS ARCOPLATE?

Arcoplate is a wear-resistant fused alloy steel plate manufactured by Alloy Steel International. It is a smooth, chromium carbide-rich overlay plate manufactured by a patented production process maximizing abrasion resistance and reducing hang up. Arcoplate was developed as an alternative to unpredictable wear rates and high friction characteristics, associated with both – quenched and tempered steel plate and the old technology, often used to manufacture traditional bulk weld overlay plates. Associated costs with unscheduled maintenance or repair are obvious, but more importantly, hidden costs relating to plant and capital productivity losses need to be eliminated wherever possible.

Inappropriate wear liner packages significantly affect fixed plant and mobile equipment in a number of ways, these include: hang up of product, spillages around plant, increased energy consumption, and increased friction causing premature wear. Alloy Steel International’s engineering and design service enables Arcoplate to be supplied as a complete wear and anti-hang-up kit, designed to suit a specific application. Arcoplate can be supplied with stud bolts, and countersunk inserts and can be pressed to shape. Arcoplate kits greatly reduce installation time and ongoing maintenance costs.

ARCOPLATE: The Ultimate Solution for Fixed Plant Wear and Mobile Plant Challenges

Addressing Common Challenges in Fixed Plant Applications and Mobile Plant of Wear Liners:

Flowability

Flowability is the ability of a liner to allow materials to smoothly flow across its surface. In fixed plants, various materials, often with high moisture content, can cause issues such as plugging and sticking. These issues can lead to complete blockages, resulting in unforeseen maintenance and downtime.

Moldability

Moldability refers to the ability of a liner to be formed to fit any shape or equipment. This involves challenges such as weldability, bendability, and formability. A liner must be versatile and adaptable to different configurations while maintaining its integrity.

Durability

Durability is the ability of a liner to last as long as possible before breaking down. Higher durability leads to lower downtime and higher productivity, making it a critical factor for every miner.

Predictable Wear Rates

Predictable wear rates are essential to avoid unplanned and unforeseen breakdowns. Having a clear understanding of the liner’s lifespan through its throughput is crucial to prevent premature maintenance or damage.

Direction of Flow

Some liners require specific orientation to avoid plugging and sticking, which can limit the arrangement and patterning options. A non-directional liner would offer greater flexibility in installation.

Available in 3 Finishes

ALLOY GRADE ABRASION ASTM G65 GLOSS IMPACT HIGH TEMP ANTI HANGUP
1600 HIGH 0.0758 HIGH 350°C YES
1600T HIGH 0.0312 HIGH 350°C YES

Flowability

ARCOPLATE boasts the smoothest surface finish, available in three finishes: Mill Finish, Pre-Polished Finish, and Ultra Polished Finish. Pre-polished ARCOPLATE has a low friction coefficient, enhancing flow properties and performance. It offers up to 23% less friction resistance than Mill Finish Utility Stainless Steel (USS). In service, the friction coefficient further decreases, improving by 39% compared to USS Polished or Q&T.

Moldability

ARCOPLATE can be cut, formed, or rolled into virtually any shape and easily attached. It must be cut by carbon arc, plasma arc, or abrasive saw – all common machining methods. ARCOPLATE can be rolled or pressed to a minimum diameter of 300mm (12 inches) with a thickness of 6/7 or 6/9. It can also be pressed using a press brake and joined with welds. ARCOPLATE can be attached using welding, plug welding, stud bolts, inserts, and fully fabricated items for larger applications.

Durability

ARCOPLATE’s laboratory and field tests show that it outlasts quenched and tempered wear plate by a factor of up to 8 to 1 and conventional welded overlay plate by up to 2 to 1, millimeter for millimeter.

Non-Directional Wear Plate

ARCOPLATE’s laboratory and field tests show that it outlasts quenched and tempered wear plate by a factor of up to 8 to 1 and conventional welded overlay plate by up to 2 to 1, millimeter for millimeter.
