AI-Powered supplier vetting

SummaryThe supplier is identified as HUNAN QILU INDUSTRIAL CO., LTD., a China-based limited company with conflicting classifications as both a trading company and manufacturer/factory. It has broad steel-related business activities, extensive stated export markets, self-operated import/export rights, and eight years of export experience. Customization, ODM, and OEM capabilities are explicitly reported. However, service-management documentation is absent, including supplier approval, corrective-action, and complaint-handling procedures. No in-stock, overseas warehouse, showroom, agent, or branch capability is reported. Financial records are referenced for 2021–2023, but no substantive financial performance evidence is provided. Production volumes and staffing are stated, although the supplier’s trading-company classification creates uncertainty regarding direct manufacturing capacity. No certifications or customer cases are documented.

After-Sales capabilityThe supplier reports no written procedures or records for service-capability assessment, corrective and preventive actions, or customer-complaint handling. It also reports no in-stock service, overseas warehouse, showroom, agent, or branch capability, although lead times are stated as one month in both peak and off-season periods.

R&D capabilityThe supplier reports total R&D-engineer experience of 6–10 years and offers ODM services, indicating some design and development capability. However, it has no available SDK, and the slices do not provide concrete innovation outputs, patents, or product-development records.

Production capacityThe supplier states production categories covering cold-drawn material, steel round bar, steel plate, and steel pipe, with substantial annual output figures and 11–20 quality-control staff. However, its classification as both trading company and manufacturer/factory is inconsistent, so the extent of directly controlled production capacity requires verification.

Customization capabilityFlexible customization is explicitly reported, together with ODM service availability and OEM service for popular brands. These statements provide direct evidence of customization and outsourced-brand production capability.

Product Q&A

Q:What is the equivalent standard for DIN 41CrAlMo7/34CrAlMo5?

The equivalent standard is JIS SACM645. Other equivalents include GB/T 3077 Grade 38CrMoAl, ASTM A29, and BS 970 Grade 905M39/905M3.

Q:What are the main applications of this steel?

It is used for nitrided parts requiring high wear resistance, high fatigue strength, and high dimensional accuracy, such as imitation dies, cylinder liners, gears, high-pressure valves, and grinding machine spindles.

Q:What are the delivery conditions for different product shapes?

Hot forged bars are usually delivered hot forged, annealed/QT, rough turned/black. Hot rolled plates are delivered hot rolled, annealed/QT, black surface. Cold drawn bars are delivered cold drawn, annealed/QT, peeled/black.

Q:What is the typical delivery time?

The delivery time is generally 30-45 days. Peak season lead time is one month, while off-season lead time is within 15 workdays.

Q:What payment terms are accepted?
