Import Alloy Steel Fixed Frame — Buy in wholesale FOB from Supplier in China

The Alloy Steel Fixed Frame supplied by Changzhou Kadi International Trade Co., Ltd is a structural component designed for metallurgical equipment applications. It is fabricated from alloy steel selected for tensile strength, resistance to deformation under load, and dimensional accuracy during machining and assembly. The frame serves as a rigid mounting or support structure within heavy industrial machinery where thermal cycling and mechanical stress demand material properties beyond standard carbon steel capabilities.

Alloy steel for this application typically incorporates chromium, molybdenum, or nickel in combinations that improve hardenability and elevated-temperature strength compared to plain carbon grades. The specific alloy designation is not stated in the source data. Standard practice for metallurgical equipment frames uses quenched and tempered low-alloy steels such as 30CrMo, 35CrMo, or 42CrMo (Chinese GB standard equivalents to AISI 4130/4140 series), achieving yield strengths of 650 to 900 MPa depending on section size and tempering temperature. Surface preparation typically includes shot blasting and primer coating for oxidation resistance during storage and installation.

Primary end-users include steel manufacturing plants, metal processing facilities, and heavy machinery OEMs requiring robust structural supports for rolling mills, continuous casting equipment, and forging presses. The fixed frame integrates with moving components that impose cyclic loading, so fatigue resistance and weldability of the alloy steel are critical design considerations. Buyers should confirm with Changzhou Kadi the exact alloy grade, whether material certificates with chemical composition and mechanical properties are available, and whether frames are supplied as bare fabrications or with machined mounting interfaces.

Changzhou Kadi International Trade Co., Ltd is located at Room 311, Building 13, No. 5, Yanzheng Middle Road, Hutang Town, Changzhou, Jiangsu, China, postal code 213100. The company holds a harbor trust tier on the platform, with a response rate of 0.00% and zero recorded average response hours. No response history means buyers cannot gauge communication speed or reliability from platform data alone.

The supplier operates as an international trading company rather than a direct manufacturer, based on their registered name and address format. No information is provided about manufacturing partnerships, years in operation, annual turnover, workforce size, or quality system certifications. Their source description mentions flexible trade options and various payment methods, but does not specify minimum order quantities, production capacity, or whether they perform final inspection before shipment. Buyers should request company registration documents, VAT invoice samples, and supplier references to validate trading experience.
