HISAN pitches ISO 3834-backed hardfaced plate solution in China

HISAN (Tianjin) Co., Ltd. is positioning its CCO plate business around welding quality, inspection, and fabrication as heavy-wear buyers demand more than a hard surface. The company says its integrated process, testing equipment, and product range are designed to support mining, cement, power, port, and steel operations.

Why it matters: - Heavy-wear buyers are increasingly judging suppliers on the full welding and fabrication chain, not just on overlay hardness. - In mining, cement, power, port and steel operations, a wear plate must be weldable, formable and testable if it is going to solve a wear problem in practice. - ISO 3834 gives buyers a common framework for evaluating welding quality, process control and inspection records.

What happened: - HISAN (Tianjin) Co., Ltd. is promoting itself as a hardfaced plate solution provider in China built around ISO 3834 welding quality. - The company operates a 16,000-square-metre facility with more than 180 professionals, including over 20 R&D specialists. - HISAN says annual capacity is about 26,000 tons across chromium carbide overlay wear plates, welding wire, overlay wear pipe, wear parts, and overlay welding and repair services. - The company is directing buyers to its website for product range, application cases and equipment details.

The details: - The core product is CCO plate, a bimetallic material that combines a wear-resistant overlay with a mild steel base plate. - Published specifications include macro-hardness of 57 to 63 HRC. - Wear performance is measured under ASTM G65 Procedure A. - The company says the plates offer larger sheet sizes and reliable formability. - Multiple grades are available for different working conditions. - HS100 is positioned for severe abrasion with low to moderate impact. - HS200 is positioned for similar duty and is offered with a range of overlay and base thickness options. - HS200 is listed with an ASTM G65 Procedure A result of 0.18 grams or less. - The plate range is used in chutes, hoppers, truck bed liners, screen plates, pipes and mill liners. - The applications span mining, cement, power, port, steel and bulk material handling. - HISAN says its welding capabilities include pipe welding machines and an eight-torch welding machine. - The company also offers cutting, forming, welding, stud attachment, assembling and grinding inside one supply system. - Welding consumables include gas shielded flux cored wires, industrial roller rebuilding wire and high-durability wear plate wire. - The wire products come in diameters from 1.2 to 4.0 mm and are packed as spools, coils or drums. - The company says the wires are designed for field work and on-site applications. - HISAN says its testing floor includes a Vickers hardness tester, a desktop Rockwell hardness tester, portable hardness and thickness testers, a SPECTRO spectrometer, a metallographic microscope and an ASTM G65 wear test machine. - The company says ISO certificates and third-party test reports are available on request.

Between the lines: - The pitch is less about a single wear plate and more about a coordinated manufacturing system. - The emphasis on welding quality, consumables and inspection suggests HISAN is trying to reduce risk for procurement teams that need repeatable performance, not just a hardness number. - The equipment list is meant to make quality auditable, with hardness, composition, carbide distribution and abrasion all verifiable in testing. - The article frames ISO 3834 as a process-control standard rather than a branding claim.

What's next: - Buyers evaluating CCO plate, welding wire or overlay wear pipe are being steered toward reviewing HISAN’s product range, application cases and equipment display. - The company is also positioning overlay welding, fabrication and repair as part of the same wear-management offering. - For procurement teams, the next step is matching plate grade, consumable and fabrication method to the specific wear environment before purchase.

The bottom line: - HISAN is selling hardfaced plate as a system, not a sheet of steel, and ISO 3834 is the framework it uses to argue that the system is consistent, testable and fit for heavy-wear service.
