HISAN outlines how to evaluate chromium carbide overlay plate quality

HISAN says buyers should judge chromium carbide overlay plate quality by structure, measurable wear data, fabrication fit and third-party testing, not by hardness alone. The company points to its HS100 and HS200 plates, ASTM G65 results and testing capability as examples for sourcing wear protection.

Why it matters: - Wear-protection buyers need proof that a chromium carbide overlay plate will perform in the field, not just a hardness number on a datasheet. - CCO plate quality affects whether liners, chutes, hoppers and other wear parts hold up under abrasion, impact and fabrication stress. - Procurement teams that compare structure, thickness, hardness, abrasion loss and test evidence can reduce the risk of premature failure.

What happened: - HISAN (Tianjin) Co., Ltd. published a guide on how to evaluate chromium carbide overlay plate quality. - The company framed quality as a mix of measurable specifications, reviewable microstructure, and application fit. - HISAN said its CCO Plate range is built around evenly distributed primary carbides, uniform overlay thickness, controlled positive tolerance and plate flatness. - The company also pointed to cut-to-size wear parts made through cutting, forming, welding, stud attachment, assembling and grinding.

The details: - HISAN’s HS100 Chromium Carbide Overlay Wear Plates list overlay thickness from 2 mm to 80 mm and base material thickness from 2 mm to 150 mm. - HS100 carries bulk hardness of HRC 58-65 and an ASTM G65 Procedure A abrasion result of 0.20 g or lower. - HISAN’s HS200 Chromium Carbide Overlay Wear Plates carry the same thickness and hardness ranges and report an ASTM G65 result of 0.18 g or lower. - HS100 lists a weld overlay composition of roughly 3% to 6.5% carbon and 16% to 30% chromium. - HS200 lists a weld overlay composition of about 3.5% to 7.5% carbon and 25% to 45% chromium, with exact content shifting by thickness. - HISAN said its testing floor includes a SPECTRO spectrometer, a portable spectrometer, a metallographic microscope and a sample grinder. - HISAN said its products are used in mining, cement, power plant, port, steel mill and bulk material handling settings. - The company said typical parts include bucket wheel excavators, truck bed liners, chute and bin liners, coal feed pipe, hoppers and transfer chutes. - HISAN’s capability page references an ASTM G65 wear test machine, a portable hardness tester and a portable thickness tester. - The company also referenced 30,000W laser cutting and advanced 5- and 8-torch welding machines in its CIM Connect 2025 announcement.

Between the lines: - A single hardness figure does not tell a buyer how a plate will behave once it is cut, welded, bolted or bent into a working component. - The real evaluation standard is whether composition, microstructure, abrasion testing and fabrication quality all point to the same result. - HISAN is trying to position quality as a chain of evidence, not a marketing claim. - The company’s mention of third-party testing through Faircloth, ATTAR and SGS is meant to support its own data, not replace it.

What's next: - Buyers reviewing wear-protection options can ask suppliers for composition, hardness, overlay-to-base thickness, ASTM G65 results, metallographic structure and third-party test references. - Teams should also confirm how the plate will be cut, formed and fixed for the target component. - HISAN says its process is shaped by a controlled quality management system, customer-oriented quality control and ongoing R&D improvement. - Project teams can review HISAN’s CCO plate range and wear-solution information at the company’s announcement, with social updates available on LinkedIn and YouTube.

The bottom line: - Chromium carbide overlay plate quality comes down to three checks: product specs, lab data and third-party signals that match the real application.
