What are the mechanical properties of 8620 steel?

Properties include tensile strength, yield strength, elongation, hardness, impact value, and non-metallic inclusion, varying based on heat treatment.

What is the maximum piece weight available?

The maximum piece weight can reach 50 tons for forging materials.

Can the steel be further surface hardened?

Pre-hardened and tempered 8620 can be further surface hardened by nitriding, but will not respond satisfactorily to flame or induction hardening.

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.
