Average Hardfacing Hardness
As the largest economy in Southeast Asia, Indonesia's economic growth is driven by heavy industries like coal and nickel mining, cement manufacturing, steel production, and maritime port trade. However, operations in these sectors face intense challenges from mechanical wear. Tropical climates, wet mud, high temperatures, and highly abrasive minerals create a destructive environment for machinery components.
Unplanned downtime in key plants can cost thousands of dollars per hour. For example, in the coal fields of East Kalimantan or the nickel extraction plants of Sulawesi, excavator bucket teeth, chute linings, and slurry transport pipes are worn down by severe abrasive friction. In Java's cement plants, grinding rollers and table segments face constant wear. This makes surface protection and wear mitigation vital for keeping machinery running reliably.
Traditional structural carbon steel wears out quickly in Indonesian operations due to low surface hardness. Applying a Chromium Carbide Overlay (CCO) using specialized welding wire forms a bimetallic structure. The structural steel backing absorbs impact loads, while the chromium-rich deposit (containing primary chromium carbides Cr7C3 with hardness up to 1500 HV) resists severe sliding abrasion. This combo extends service life by up to 5-10 times compared to standard carbon steels.
The global demand for wear-resistant materials is shifting toward self-shielded open arc flux-cored wires. Previously, heavy equipment was repaired using manual metal arc (MMA) electrode welding or gas metal arc welding (GMAW), which requires external shielding gas. Now, self-shielded flux-cored wires (FCAW-S) are preferred because they don't need external gas cylinders. This makes them ideal for quick field repairs in remote mining zones across the Indonesian archipelago, even in windy conditions.
Additionally, modern supply chains require certified alloys that comply with global standards like DIN 8555 (specifying deposit classifications) and ASTM G65 (measuring dry sand/rubber wheel abrasion resistance). Purchasing managers look for manufacturing consistency, stable alloy chemistry, and predictable wear performance from factories that run advanced Quality Management Systems (QMS).

Detailed Catalog →Under severe abrasive sliding wear conditions, CCO plates like the Runxing RX-m series typically last 4 to 8 times longer than standard abrasion-resistant (AR) steels (like AR400 or AR500). They can also last up to 15 times longer than typical structural carbon steels. CCO plates achieve this because the overlay contains a high concentration of primary chromium carbide particles (Cr7C3) embedded in a tough iron-alloy matrix.
Yes. Our OEM self-shielded flux-cored welding wire is designed for open arc welding without an external shielding gas. This makes it highly suitable for onsite repairs in windy locations, such as open-pit mines in Kalimantan and port facilities, where gas shielding can easily be disrupted by wind.
We maintain strict ISO 9001 quality compliance at our manufacturing facility in Tangshan, Hebei. Our partner, Hebei Yuwan International Trade Co., Ltd., handles all export processes. This includes customs clearance, logistics, and processing transport documents to ensure efficient delivery to ports like Jakarta, Surabaya, and Balikpapan.
Our standard wear plates and hardfacing wires contain 3.5% to 5.5% Carbon and 20% to 35% Chromium. This combination creates a high density of primary chromium carbides (with typical hardness values ranging from 58 to 65 HRC). We can also adjust the formulation with Niobium, Boron, or Tungsten to meet specific requirements for high-temperature resistance or high-impact resistance.
We supply standard-sized overlay plates (e.g., 1400x3400mm) and also provide full custom cutting, rolling, bending, and stud welding services. You can send us your component drawings (e.g., for hopper linings, fan blades, or transition pipes), and our factory will fabricate ready-to-install parts according to your dimensions.
