HISAN lays out how to choose CCO plate thickness

HISAN published a technical guide on July 29, 2026, explaining how buyers should size chromium carbide overlay plates for heavy-wear applications. The company says the right choice depends on matching overlay and base thickness to the wear environment, then verifying performance with hardness and abrasion data.

Why it matters: - CCO plate thickness affects both wear life and structural strength in mining, cement, power generation, ports, steel mills, and bulk material handling. - A mismatch between overlay thickness and base thickness can lead to repeated liner replacements instead of longer service intervals. - Buyers need a thickness spec that matches the application, not just a single number from a catalog.

What happened: - HISAN published a technical guide on choosing chromium carbide overlay, or CCO, plate thickness for heavy-wear applications. - The guide was released July 29, 2026, and centers on how overlay thickness and base thickness work together in chutes, bins, crusher liners, and other wear parts. - HISAN (Tianjin) Co., Ltd. framed the guide as a decision aid for industrial buyers and fabricators.

The details: - CCO plate is a bimetallic wear material with a chromium-carbide-rich overlay fused to a mild steel base plate. - The overlay provides abrasion resistance. - The base plate provides structural integrity, weldability, and attachment strength. - HISAN says thickness should be read as a pairing, not as one nominal figure. - HS100 and HS200 are positioned for severe abrasion with low-to-moderate impact. - HS100 and HS200 offer overlay thickness from 2 to 80 millimeters and base thickness from 2 to 150 millimeters. - HS-F targets applications where material hang-up is the main problem. - HS-F uses a no-weld-bead surface to reduce sticking. - HS-F lists overlay thickness from 4 to 35 millimeters and base thickness from 5 to 50 millimeters. - HS-X is the customizable product family. - HS-X matches thickness and alloy system to customer requirements and lists coating thickness from 4 to 80 millimeters and base thickness from 4 to 150 millimeters. - HS100 carries bulk hardness of HRC 58-65 and ASTM G65 performance of 0.20 grams or lower. - HS200 carries bulk hardness of HRC 58-65 and ASTM G65 performance of 0.18 grams or lower. - HS-F carries bulk hardness of 58 to 65 HRC. - HISAN says plate selection should begin with the wear environment, including abrasion level, impact level, material hang-up risk, and component shape. - The guide names chutes, bins, screens, transfer pipes, fan housings, crusher liners, and conveyor components as common use cases. - HISAN says thickness specifications should be verified against hardness and abrasion test data. - HISAN cites a portable thickness tester, ASTM G65 wear test machine, desktop Rockwell hardness tester, metallographic microscope, and SPECTRO spectrometer in its quality process. - HISAN says it can cut plates to size and fabricate them through cutting, forming, welding, stud attachment, assembling, and grinding. - HISAN says that in-house fabrication reduces coordination risk between plate supply and installation.

Between the lines: - The guide turns thickness selection from a purchasing decision into an engineering decision tied to performance data. - HISAN is positioning itself as both a materials supplier and a fabrication partner, not just a plate seller. - The emphasis on verification suggests buyers are being pushed to compare suppliers on testing method as well as on published thickness ranges.

What's next: - HISAN says buyers should submit application details, drawings, sample parts, or component information for review before requesting a quote. - The company says those inquiries can help determine whether HS100, HS200, HS-F, or an HS-X custom solution fits the application. - Buyers can find more information in HISAN's announcement.

The bottom line: - HISAN's core message is simple: choose CCO plate thickness as an overlay-plus-base system, match it to the wear environment, and verify it with test data before ordering.
