Import 4130 Forged Steel Round Bar — Buy in Bulk from Supplier in China

Zhuhong Forging Co., Ltd supplies 4130 forged steel round bars, a low-alloy chromium-molybdenum steel known for its weldability and strength in high-temperature applications. The bars are produced through a controlled forging process to refine grain structure, followed by heat treatment to optimize mechanical properties. This grade is widely used in industries requiring a balance of strength, ductility, and resistance to fatigue.

The 4130 alloy typically contains 0.28-0.33% carbon, 0.80-1.10% chromium, and 0.15-0.25% molybdenum, offering good hardenability and toughness. Standard diameters for forged round bars range from 50 mm to 500 mm, with lengths customizable to buyer specifications. The bars are often supplied in the normalized or annealed condition, though quenching and tempering can be applied for higher strength applications. Typical industry standards include ASTM A322 for steel bars, alloy, standard grades.

Primary applications include structural components, shafts, and machinery parts in automotive, aerospace, and oil and gas sectors. The bars are exported with flexible MOQs and can be shipped under FOB or CIF terms, depending on buyer preference. Buyers should confirm the specific heat treatment and mechanical properties required for their use case, as these directly impact performance in service.

Zhuhong Forging Co., Ltd is located in Yangshi Industry Park, Huishan District, Wuxi, Jiangsu Province, China. The company specializes in the production of forged steel bars, including alloy and carbon steel grades, for industrial applications. Its manufacturing process includes forging, heat treatment, and machining to meet precise customer specifications for diameter, length, and mechanical properties.

The supplier operates under the harbor trust tier, indicating a verified manufacturing and export capability. While the company’s response rate and average response hours are not currently specified, it maintains a focus on delivering high-precision forged products for global markets. Buyers are advised to contact the supplier directly to confirm production lead times, certification status, and additional quality control measures.
