Import Crusher Hammer — Buy in Bulk from Supplier in China

Chengde Rongmao Cast Steel Co., Ltd. produces crusher hammers using cast high-chromium alloy steel, suitable for high-impact crushing applications. The hammers are designed for use in jaw, cone, and impact crushers, with weights ranging from 2.2 kg to 8.0 kg and lengths from 150 mm to 300 mm. These are not forged but cast in sand molds, with a typical chromium content of 12-18% to enhance abrasion resistance.

The material follows standard high-chromium white cast iron grades such as ASTM A532 Class IIIA, which is common in mining applications. The hammers feature a martensitic matrix with embedded chromium carbides, providing superior wear resistance over plain carbon steel. Surface roughness is not specified, but casting tolerances are ±3% on weight and ±2 mm on length. These hammers are not heat-treated post-casting, relying on alloy composition for performance.

Buyers in cement plants, mineral processing facilities, and scrap recycling operations in Africa, South America, and Southeast Asia use these hammers as direct replacements. Packaging is in bulk steel drums or palletized wooden crates, holding 20 to 50 units per shipment. Minimum order quantities are not listed and must be confirmed directly. Lead times are estimated at 30 to 45 days after order confirmation. Incoterms offered include FOB Tianjin or CIF, depending on destination.

Chengde Rongmao Cast Steel Co., Ltd. is a foundry located in Chengde, Hebei Province, China, specializing in cast steel wear parts for industrial crushers. The company’s facility is situated in a known industrial zone, but no public records confirm its establishment date, workforce size, or export volume. The listing does not mention certifications, quality management systems, or client references. Response metrics are not tracked, and no third-party verification is disclosed.

The supplier claims engineering for durability and energy efficiency but provides no technical documentation, test reports, or process controls. There is no mention of post-casting heat treatment, surface finishing, or inspection protocols. Buyers cannot verify claims about 'precision engineering' or 'high standards' without requesting independent test data. The absence of response rate and verification signals indicates limited buyer interaction history.
