HISAN spotlights ISO 9001 controls for chromium carbide overlay plates

HISAN (Tianjin) Co., Ltd. is positioning its chromium carbide overlay plate line around documented quality control, Cr7C3 carbide structure, and test data for buyers in heavy industry. The company says its process links composition, hardness, thickness, abrasion testing, and inspection under an ISO 9001-style quality system before shipment.

Why it matters: - Heavy-industry buyers want proof of wear performance before installing chromium carbide overlay plate. - Documented control of carbide structure, hardness, and abrasion results can reduce procurement risk for mining, cement, steel, port, and power applications. - ISO 9001-style process control gives importers and project teams a paper trail for supplier qualification.

What happened: - HISAN (Tianjin) Co., Ltd. outlined its chromium carbide overlay plate quality-assurance approach around Cr7C3 carbide control and ISO 9001 process discipline. - The company says its CCO Plate family is built for buyers who want verifiable data on composition, microstructure, hardness, thickness, and abrasion performance. - The announcement was issued from Tianjin, China, on July 29, 2026.

The details: - HISAN manufactures its CCO plate by cladding a wear-resistant overlay onto a mild steel base plate. - The bimetallic structure is designed to combine wear resistance with ductility for forming and welding. - The mild steel base can be welded or bolted for on-site fabrication. - The overlay carries a macro-hardness of 57 to 63 HRC. - HISAN says the plate family is used in transfer chutes, hoppers, liners, and pipes in mining, iron and steel, cement, port, and coal-fired power operations. - ISO certificates and third-party test reports are available on request. - The HS100 chromium carbide overlay wear plate lists roughly 3.0% to 6.5% carbon and 16% to 30% chromium in the weld overlay. - HS100 overlay thickness ranges from 2 mm to 80 mm. - HS100 base material thickness ranges from 2 mm to 150 mm. - HS100 has a bulk hardness of HRC 58 to 65. - Standard sheet sizes include 1400 x 3000 mm and 2000 x 3000 mm. - Other sizes and thicknesses are available on request. - The HS200 grade extends the same plate concept with a higher chromium range for heavier-duty service. - HISAN reports HS100 abrasion performance under ASTM G65 Procedure A with mass loss of no more than 0.20 grams. - The company pairs the wear test data with an X200 metallographic view of the overlay structure. - HISAN's testing floor includes a SPECTRO spectrometer, a portable spectrometer, Vickers hardness testers, desktop Rockwell testers, portable hardness testers, a portable thickness tester, an ASTM G65 wear test machine, and a metallographic microscope. - The production workshop includes plasma cutting, flattening and bending machines, a welding wire production line, pipe welding machines, and an eight-torch welding machine. - HISAN also cuts plates to size and fabricates wear parts through cutting, forming, welding, stud attachment, assembling, and grinding. - The CCO range includes HS100, HS200, HS300, HS600, HS-F, and custom HS-X grades. - HS-F is a smooth-surface plate made without raised weld beads and is aimed at sticky flows such as coal preparation. - HS-X is designed for project-specific composition needs. - HISAN describes itself as a high-tech manufacturer of chromium carbide overlay wear-resistant plates, overlay wear pipes, welding wires, wear parts, and related wear-resistant solutions. - The company says quality control and responsive technical service are central to its operating approach.

Between the lines: - The pitch is not just about a product line. It is about making wear resistance measurable enough for procurement teams to compare suppliers on data, not branding. - The combination of metallurgy, test reports, and in-house fabrication suggests HISAN is selling a specification-to-installation workflow, not only raw plate. - The emphasis on HS-F and HS-X shows the company is trying to cover both difficult material-handling conditions and custom engineering jobs.

What's next: - Buyers can request ISO certificates, third-party reports, and product specifications before qualifying the plates for service. - HISAN invites inquiries on chromium carbide overlay plate specifications, Cr7C3 carbide quality, ISO 9001 quality assurance, and factory capability through its website at the company's announcement. - The company also lists social channels on LinkedIn and YouTube for additional product and factory information.

The bottom line: - HISAN is betting that traceable carbide structure and test-backed quality control will matter as much as wear resistance itself in industrial buying decisions.
