HISAN pitches CCO plate as a tougher alternative to AR400 in severe abrasion

HISAN (Tianjin) Co., Ltd. is framing chromium carbide overlay plate as a better fit than AR400 steel for mining, cement and bulk-handling equipment that faces constant sliding abrasion. The company points to its HS200 product data, in-house testing and fabrication capabilities, and a broader wear-products lineup as buyers weigh liner life against downtime.

Why it matters: - Maintenance teams in mining, cement and bulk material handling lose time and money when chutes, hoppers and transfer points wear out early. - The material choice affects both liner life and how often equipment must be shut down for replacement. - The comparison is not just about hardness. It is about whether the wear surface can survive the actual abrasion pattern.

What happened: - HISAN (Tianjin) Co., Ltd. positioned its chromium carbide overlay plate, or CCO plate, as an abrasion-focused alternative to AR400 steel. - The company outlined a CCO Wear Plate vs AR400 Steel comparison based on wear mechanism, fabrication fit and test data. - HISAN highlighted its HS200 product line as the main example of the overlay plate approach.

The details: - CCO plate is a bimetallic material made by fusing a high-chromium carbide layer onto a mild steel base. - AR400 steel is a quenched and tempered, through-hardened plate that balances hardness and formability. - HISAN said its overlay approach concentrates chromium carbide on the wear-facing surface while keeping the base formable. - HISAN said HS200 delivers bulk hardness in the HRC 58-65 range. - HISAN said HS200 posted an ASTM G65 Procedure A abrasion result at or below 0.18 grams in its product documentation. - HISAN said its overlay platform also includes HS100, HS300, HS600, HS-F and HS-X. - HISAN said those lines are tuned for different overlay chemistries, impact tolerance and surface conditions. - HISAN said its CCO plates can be cut, formed, welded and assembled into finished wear parts. - HISAN said sizes are available on request. - HISAN lists mining, cement, power generation, ports, steel mills and bulk material handling among its documented applications. - HISAN said its facility includes hardness testers, spectrometers, an ASTM G65 wear test machine and a metallographic microscope. - HISAN said its workshop includes bending, flattening and plasma cutting equipment. - HISAN said its product range also includes overlay wear pipes, welding wires and abrasion resistant steel plates. - HISAN provided a company website for more information: the company's announcement - HISAN also listed social media links for LinkedIn and YouTube

Between the lines: - The pitch is aimed at buyers who care more about wear-life economics than single-number hardness claims. - The company is trying to separate a general-purpose wear steel from a purpose-built overlay system. - The emphasis on in-house testing suggests HISAN wants buyers to view the product as measurable rather than promotional.

What's next: - Buyers evaluating coal chutes, storage bins, mining equipment, cement lines, ports and steel mills are being invited to send operating conditions, drawings or thickness requirements. - HISAN is positioning its one-stop wear-protection lineup as a sourcing path for teams that want both material supply and fabrication support. - The practical decision still comes down to the wear condition: AR400 for moderate wear and formability, CCO plate for severe sliding abrasion.
