HISAN pitches CCO plate as a heavy-milling alternative to Hardox wear plate

HISAN (TIANJIN) CO.,LTD is positioning its chromium carbide overlay wear plates for heavy milling, mining, cement and bulk handling applications where abrasion concentrates on liners and other replaceable parts. The company says its bimetallic plates, fabrication capabilities and in-house testing give buyers a surface-wear solution distinct from Hardox’s through-plate approach.

Why it matters: - Heavy milling equipment fails first at wear surfaces, not at the strongest structural steel. - The choice between CCO Plate and Hardox Wear Plate affects liner life, downtime, fabrication fit and maintenance planning. - In abrasive environments such as mining, cement, power generation, steel and bulk material handling, the wear strategy can shape operating cost more than the base machine design.

What happened: - HISAN (TIANJIN) CO.,LTD framed its CCO Plate vs Hardox Wear Plate comparison around heavy milling applications. - The company described its product line as a bimetallic wear plate with a wear-resistant overlay on a mild steel base. - HISAN said its CCO plates are aimed at liners, chutes, hoppers and grinding surfaces where wear is concentrated. - The company said Hardox wear plate follows a through-plate hardness-and-toughness model, while HISAN CCO plate places chromium carbide and complex carbides at the wear surface.

The details: - HISAN said its CCO structure combines a high-volume-fraction chromium carbide or complex carbide overlay with a mild steel backing. - The overlay handles abrasion, while the backing supports welding, bolting, cutting, forming and assembly. - HISAN said its CCO category includes uniform overlay thickness, macro-hardness of 57 to 63 HRC, ASTM G65 Procedure A abrasion testing, cut-to-size wear parts and in-house fabrication. - The HS200 plate is designed for severe abrasion with low-to-moderate impact. - HISAN said HS200 carries bulk hardness of 58 to 65 HRC and an ASTM G65 Procedure A result of 0.18 grams or less. - The HS300 plate targets high-abrasion conditions with medium-to-high impact. - HISAN said HS300 uses a blend of chromium, niobium, molybdenum, vanadium and titanium carbides. - The HS600 plate is built for extremely severe abrasion. - HISAN said HS600 carries a complex carbide overlay rated at 60 to 65 HRC. - The company linked HS200 to coal, power plant, chute and bunker positions. - HISAN linked HS300 and HS600 to cement, mining, steel and bulk material handling. - The company pointed to cement mill internals, roller presses, mill rollers, grinding surfaces and mill casings as key use cases. - HISAN said its factory can cut, form, weld, attach studs, assemble and grind wear parts. - The company said that approach lets buyers match liners to a specific position, flow angle and maintenance window. - HISAN said its Company Ability includes a Vickers hardness tester, portable hardness and thickness testers, a SPECTRO spectrometer, an ASTM G65 wear test machine, a metallographic microscope and a desktop Rockwell hardness tester. - The company said it operates a 16,000 square-metre facility with more than 180 professionals, over 20 R&D specialists and an annual capacity of 26,000 tons. - HISAN said its product range also includes welding wire, overlay wear pipe, wear parts and overlay welding and repair services. - The company provided its website as More information. - HISAN also listed social links on LinkedIn and YouTube.

Between the lines: - The comparison is less about one plate being universally better and more about matching the wear mechanism to the material structure. - Hardox remains positioned as a strong through-plate option for structures that need overall toughness, flexibility and reduced weight. - HISAN is arguing that surface-dominant abrasion favors an overlay plate because the wear investment sits where damage occurs. - The factory message matters because buyers need a part that can be fabricated, tested and installed, not just a hard sheet of metal.

What's next: - HISAN is inviting operators to share working conditions, thickness needs, dimensions and testing requirements. - The company said it can support custom bimetallic wear plate specifications for mill liners, chute liners, hopper liners and grinding surfaces. - Buyers comparing CCO Plate vs Hardox Wear Plate will likely keep weighing wear mechanism, installability, traceability and resupply alongside raw hardness numbers.

The bottom line: - HISAN is selling CCO plate as a factory-built answer for severe surface wear, while Hardox remains the better-known through-plate route for broader structural toughness.
