Shandong Speed Steel Seiko Factory Co., Ltd. manufactures carbon steel castings in Qingdao, Shandong Province, China. The product is offered in the standard grades Q195, Q215, Q235, Q255 and Q275, each defined by a specific carbon content range. These castings are supplied either as rough‑machined blanks or as finished parts according to buyer specifications. The material exhibits a combination of strength, plasticity and toughness that suits heavy‑load applications.
Carbon steel of these grades typically contains 0.15‑0.30% carbon together with small amounts of silicon and manganese that influence hardness and ductility. Typical tensile strength for the listed grades ranges from 300 to 500 MPa, with a Brinell hardness of 120‑180 HB. Standard casting tolerances are ±0.5 mm and the as‑cast surface finish is usually Ra 3.2 µm. Normalizing heat treatment can be applied to raise strength while retaining reasonable ductility.
The castings are commonly used in rolling‑mill stands, hydraulic‑press bases, railway couplers and other components that endure high static loads. Buyers such as machinery manufacturers, construction firms and original equipment makers typically order in bulk quantities and request FOB Qingdao or CIF terms. Because the listing does not disclose minimum order quantity, lead time or certification status, importers should confirm these details directly with the supplier before placing an order.

Before placing an order, verify the exact grade, chemical composition and any required certifications such as a mill test report. Ask the supplier to provide recent test certificates and confirm that the casting dimensions meet your engineering drawings. Ensure that the supplier’s factory registration and export licences are current for shipments from China.
Typical lead times for bulk steel castings are four to six weeks, but the exact schedule depends on order size and any post‑casting machining. Importers should confirm the preferred Incoterm - FOB Qingdao or CIF - and negotiate payment terms, often a telegraphic transfer after sample approval. Shipping is usually arranged by sea freight in standard containers or bulk freight, with the option for inland trucking to the port.
Quality assurance should include a third‑party inspection before loading, focusing on dimensional checks, hardness testing and surface defect evaluation. Request a non‑destructive testing report if the components will bear critical loads. Retain all inspection certificates, packing lists and the mill test report to support customs clearance and downstream quality control.
