Shandong Speed Steel Seiko Factory Co., Ltd. supplies malleable iron castings that are produced by heat‑treating white cast iron into a ductile material. The castings are made from malleable cast iron with a ferritic‑pearlitic structure and are supplied in the KTH300‑06 grade. This grade conforms to the KTH300‑06 specification and is comparable to ASTM A220 requirements for mechanical performance. The product is offered as a standard industrial casting suitable for further machining.
Typical industry practice offers grades such as KTH300‑06 and other ASTM‑A220 compliant alloys, providing tensile strengths in the range of 350 - 450 MPa and Brinell hardness between 150 - 180 HB. Malleable iron’s graphitised micro‑structure gives it superior plasticity and impact resistance compared with grey cast iron, allowing it to replace carbon steel in many applications. Standard dimensional tolerances for such castings are ±0.5 mm, with surface finishes commonly specified at Ra 1.6 µm.
Common applications include rear‑axle housings, steering mechanisms, low‑pressure valves, pipe joints and other components that experience shock and vibration. Automotive manufacturers, agricultural equipment makers and pipe‑fitting fabricators are typical buyers of these castings. Trade terms such as minimum order quantity, lead time and Incoterms are not disclosed in the listing and should be confirmed directly with the supplier before placing an order. The supplier notes that malleable iron castings are competitively priced in global trade.

Before placing an order, importers should obtain the supplier’s material certification confirming the KTH300‑06 grade and the heat‑treatment process used. Request a recent mill test report that details tensile strength, hardness and chemical composition. Verify that the casting dimensions meet the ±0.5 mm tolerance and that surface finish specifications align with project requirements. If possible, arrange a factory audit or third‑party inspection to validate production capabilities.
Logistics discussions should establish the preferred Incoterm, such as FOB Qingdao or CIF Shanghai, to clarify responsibility for freight and insurance. Lead time for heat‑treated malleable iron castings is not listed, so buyers must ask the supplier for a production schedule. Payment terms are typically negotiated on a letter of credit basis, but the exact arrangement should be agreed in the contract. Confirm the weight per crate and total container load to ensure efficient shipping planning.
Upon arrival, importers should conduct a visual inspection for surface defects and verify dimensions with calibrated gauges. A non‑destructive test such as ultrasonic or magnetic particle inspection can detect internal cracks that may arise during handling. Retain the supplier’s mill test certificates, heat‑treatment records and packing list as part of the documentation package for customs clearance. Engaging a qualified third‑party inspection agency before shipment can further reduce the risk of non‑conformance.
