Ductile Iron Bar 500-7
Hengong Machinery Technology Co., Ltd supplies Ductile Iron Bar 500‑7, a spheroidal graphite cast iron product meeting EN‑GJS‑500‑7 and ISO 1083 specifications. The grade guarantees a minimum tensile strength of 500 MPa and an elongation of at least 7 %, making it suitable for high‑stress components. Bars are offered in diameters from 30 mm up to 600 mm and are cut to standard lengths of 1.5 m or 3 m. The material composition follows the typical chemical limits for grade 500‑7, providing a balance of strength and ductility.
In the cast‑iron industry, grade 500‑7 is widely used for automotive parts, pump housings, pipe fittings and heavy‑duty machinery. Typical surface finish is a roughness (Ra) of 6 µm, and the bars are supplied without additional coating, allowing end users to apply bespoke treatments. The supplier lists the product under the umbrella of ductile and gray iron offerings, indicating the ability to source alternative grades if required.
Customers such as foundries, engineering contractors and large‑scale manufacturers often request these bars for forging or machining operations. While the listing does not disclose minimum order quantities or pricing, buyers should contact Hengong Machinery Technology Co., Ltd to confirm availability and shipping options. Standard trade terms include FOB from the port of Tianjin, with payment typically via L/C or T/T after receipt of the pro‑forma invoice.

Sourcing Ductile Iron Bar 500-7 from Hengong Machinery Technology Co., Ltd - China Import Guide
Importers should first confirm the bar’s grade, tensile strength, and chemical analysis certificates before finalising the purchase. Request a mill test report that lists the exact composition and mechanical properties for the batch you intend to buy.
Logistics typically involve FOB from the nearest Chinese port, with Incoterms such as FOB or CIF to be agreed. Verify the expected lead time, shipping schedule and payment terms - usually an irrevocable L/C or T/T after the pro‑forma invoice.
Upon receipt, a third‑party inspection can verify dimensions, surface roughness and weight against the specifications. Retain the mill test report and any SGS inspection documents to facilitate customs clearance and quality assurance.
