Langtuo Cp., Ltd. supplies casting iron in two distinct grades: grey cast iron GG-20 and GG-25, and ductile iron FCD 400 and FCD 450, as stated in the source. These grades correspond to tensile strengths of 200 MPa and 250 MPa for grey iron, and 400 MPa and 450 MPa for ductile iron, respectively. The material is manufactured to meet ASTM A48 and ISO 185 standards, with carbon content controlled for consistent graphite formation and mechanical performance.
Grey cast iron (GG-20/25) features flake graphite, offering good damping and machinability, while ductile iron (FCD 400/450) contains spheroidal graphite, providing higher elongation and impact resistance. The supplier does not specify alloying elements like nickel or copper, but these are typically added to enhance strength in ductile grades. Surface finish is not detailed, but industrial castings of this type are usually delivered with as-cast surfaces requiring secondary machining for precision parts.
This casting iron is used in machinery frames, automotive brake components, pipeline fittings, and construction equipment. Buyers include OEMs and replacement part distributors in Southeast Asia, Africa, and Eastern Europe. Packaging is standard for bulk shipments: no pallets or protective coating mentioned. Trade terms include FOB and CIF, but MOQ and lead time are not specified. Buyers must request these details directly.

Verify material grade certification before placing an order. Request a mill test certificate for each batch showing chemical composition, tensile strength, and elongation per ASTM A48 and ISO 1083. Confirm that the supplier can provide metallurgical reports with microstructure images. Do not accept verbal assurances - demand written documentation linked to shipment IDs.
Clarify Incoterms: FOB or CIF must be confirmed in writing. Ask for estimated lead time from order placement to port of loading, and whether the supplier handles export documentation. Payment terms are not stated - standard options include 50% advance against proforma invoice and 50% against BL copy. Confirm if the supplier accepts LCs and which bank they work with.
Conduct incoming inspection using a portable hardness tester and ultrasonic thickness gauge. Sample at least 5% of the batch for destructive testing. Check for surface cracks, sand inclusions, and misruns. Ensure packaging is labeled with grade, batch number, and origin. Retain samples for 60 days and request a Certificate of Origin and Packing List matching the container contents before customs clearance.
