What is the difference between 304 and 316 stainless steel?

316 contains Molybdenum (Mo), offering better corrosion resistance in high-temperature, chemical, and seawater environments compared to 304, though it is more expensive.

Can you provide free testing reagents for stainless steel?

Yes, we provide stainless steel testing reagents and detailed instructions for free upon request when placing an order.

What support is available for distributors?

Distributors purchasing over 30,000 USD receive free Gauss meters and magnetic pole detection sheets, plus access to internal magnet learning materials.

AI-Powered supplier vetting

SummaryThe supplier demonstrates established manufacturing, customization, export, and service-process capabilities. It reports annual capacity of 4,000 tons of neodymium magnets, 5,000 tons of rubber magnets, and 1,000 tons of samarium cobalt magnets, with flexible customization, ODM, and OEM services. Quality and service management are supported by written procedures and records, an approved supplier list, corrective and preventive action procedures, and finished-product inspection instructions. Certifications listed include RoHS and CE. The supplier has no SDK, overseas warehouse, showroom, agent, branch, or stated overseas service coverage, but has participated in Concrete Asia. Financial information is limited to year references, so credibility cannot be fully assessed. Innovation is evidenced by new products in the past year and ERP use, although no SDK is available. Customer-related evidence includes OEM service for well-known brands, but no specific customer names or case details are provided.

Supplier typeThe supplier is presented as a magnet manufacturer with reported production of neodymium, rubber, and samarium cobalt magnets. Its ODM and OEM offerings indicate it also operates as a manufacturing service provider for customized and branded products.

CertificationsThe supplier reports holding RoHS and CE certifications, along with other unspecified certifications. These stated certifications provide explicit compliance evidence, although the scope and validity details are not supplied.

After-Sales capabilityService capability is supported by written procedures, followed records, corrective and preventive action procedures, and an updated approved-supplier list. However, the supplier reports no overseas warehouse, showroom, agent, or branch, and lists zero countries with overseas services, limiting evidence of localized after-sales support.

R&D capabilityThe supplier reports having introduced new products during the past year, provides flexible R&D design services, and offers ODM services. It also uses ERP for production, procurement, quality control, and logistics management, but explicitly has no available SDK and reports zero for its sustainable-development technical transformation and big-data capabilities.

Production capacityReported annual capacity is 4,000 tons of neodymium magnets, 5,000 tons of rubber magnets, and 1,000 tons of samarium cobalt magnets. Production-related controls include uniform finished-product inspection instructions, while service procedures and records are established; stated lead times are within 15 workdays off-season and one month during peak season.

Customization capabilityThe supplier explicitly provides flexible customization through design and R&D services. It also reports ODM capability and OEM service for popular brands, supporting both customized product development and branded manufacturing.

Client casesThe supplier states that it provides OEM services for well-known brands and has participated in the Concrete Asia offline trade show. No customer names, project descriptions, order examples, or verifiable case outcomes are provided, so the depth of its customer track record cannot be fully assessed.

Product Q&A

Q:What should I do before purchasing a magnetic bar?

Confirm the shape, size (standard 25mm diameter, max 2500mm length), gauss (2500-14000Gs), working temperature, material corrosion resistance, tube cover type (316L/304), threaded hole configuration, and quantity.

Q:How does the magnetic filter tube work?

It consists of a 304 or 316 stainless steel tube, pole plate, end plug, and permanent magnet. Iron-containing substances are attracted to the pipe wall by the magnetic force, ensuring equipment integrity and product safety.

Q:What are the risks of buying low-cost magnetic filter rods?

Unethical companies may reduce magnet volume, use shredded magnets, use secondary magnets, or thin the stainless steel pipe, leading to uneven surfaces, tube collapse, efficiency drops, and shortened service life.

Q:What are the main factors causing demagnetization?

Demagnetization is caused by high temperatures exceeding resistance grades, impurities in magnet material, strong external magnetic fields, frequent impacts, and humidity.

Q:How often should the magnetic bar strength be checked?

The usual inspection frequency is 1 to 3 months. In harsh environments like high temperature or vibration, the frequency should be increased.
