The Grade 63 high‑strength mining round link chain is offered in a size range of 34 mm to 126 mm per link. It is classified as Grade B (63) according to the supplier’s grading system, which indicates a tensile strength around 630 MPa. The chain is manufactured from alloy steel, a material commonly used for heavy‑duty mining applications. It is supplied with a painted or slushed oil coating to resist corrosion in harsh environments.
The chain conforms to ISO 9001 quality management standards and to the Chinese standard GB/T 12718‑2009 as well as DIN 22252:2001, which specify dimensions, material requirements and testing methods for mining chains. Fatigue performance is a key parameter; the supplier guarantees a minimum of 30 000 load cycles before failure. Typical link design for this type of chain includes a round bar with a central pin and a full‑height eye, providing high load distribution. Standard tolerances for link length are ±0.5 mm and for pin diameter ±0.2 mm, which are typical for mining‑grade chains.
End users such as scraper conveyor manufacturers and loader equipment makers rely on this chain for robust material handling. The listing does not disclose minimum order quantity, price, lead time or payment conditions, so buyers should request those specifics directly. Confirming the chain’s compliance with the cited standards and obtaining a material test report are advisable steps before finalising an order.

Prior to placing an order, verify that the chain meets the Grade 63 (Grade B) classification and that the alloy‑steel composition conforms to GB/T 12718‑2009 requirements. Request a mill test certificate and a coating thickness report to confirm the painted or slushed oil finish. Ensure that the supplied dimensions fall within the stated tolerances of ±0.5 mm for link length and ±0.2 mm for pin diameter.
Discuss the preferred Incoterm, such as FOB Qingdao or CIF Shanghai, and obtain the supplier’s estimated production lead time for the requested size range. Since payment terms are not listed, negotiate standard B2B arrangements, for example a 30 % T/T advance with the balance secured by an irrevocable L/C. Sea freight is the usual transport mode for bulk mining chains, and you should confirm container loading plans with the supplier.
Arrange a pre‑shipment inspection by a recognised third‑party agency to verify link dimensions, material grade and coating quality against the supplied specifications. Ask for the final commercial invoice, packing list and certificates of conformity as part of the shipping documentation. Maintaining these records will facilitate customs clearance and assure downstream quality control.
