This precision-forged stainless ring gear is manufactured from SNCM439 alloy steel, delivering high tensile strength and fatigue resistance for heavy-duty mechanical systems. The listed dimensions are an outer diameter of 200.9 mm, an inner diameter of 91 mm, and a width of 140 mm, with the supplier confirming stainless steel grades 304, 316, and 321 available on request. Forged to ASTM A276 standards, it is designed for applications where shock loads and cyclic stress are common, such as automotive transmissions and industrial machinery.
The material composition is a key differentiator, with SNCM439 offering superior toughness compared to standard carbon steels, while the stainless grades provide corrosion resistance in harsh environments. Typical industry specifications for forged ring gears include hardness values of 25-35 HRC for case-hardened variants, though the supplier does not state a hardness value for this listing. Surface finishing is often ground or machined to achieve a Ra 0.8-1.6 µm roughness, a standard for precision gears, and teeth are usually cut to AGMA Class 10-12 accuracy for smooth meshing.
Buyers in the automotive, marine, and heavy machinery sectors use these forged ring gears in differential assemblies, slewing drives, and power transmission systems. Bulk orders are packed in export-ready wooden crates or steel pallets to prevent deformation during transit, with the supplier indicating flexibility in MOQ and global shipping terms. Verification of exact grades, hardness, and surface treatments should be confirmed with the supplier, as these details are critical for matching application requirements.

Zhangqiu Yubin Petrochemical Fitings Factory operates from Chizitou, Puji Town, in Zhangqiu City, Shandong Province, a region known for its metalworking and industrial components manufacturing. The supplier is classified under the harbor trust tier, indicating a baseline level of verification for international trade, though the response rate and average response hours are currently listed as zero, suggesting limited engagement on the platform.
The factory specializes in forged metal components, with this listing focusing on stainless ring gears for industrial applications. While the profile does not provide details on production capacity, certifications beyond ASTM A276, or specific client references, the supplier’s location in Shandong aligns with China’s established supply chain for forged steel products. Buyers should confirm the availability of specific grades, such as 304 or 316, as well as any additional certifications like ISO 9001 or CE, which are often expected for European or North American markets.
Our stainless forged ring gear is precision-forged from high-grade stainless steel, making it ideal for demanding industrial gear applications in machinery, automotive, and marine systems. Available in304 and 316 grades with sizes ranging from 100mm to 1500mm diameter, these custom forgings meet ASTM A276 standards and are ready for export packaging.

Before ordering, verify the exact material grade and heat treatment applied to the ring gear, as these directly impact performance in high-stress applications. SNCM439 alloy steel offers high strength, but stainless grades 304, 316, or 321 may be necessary for corrosion resistance in marine or chemical environments. Request mill test certificates or third-party inspection reports to confirm material properties and compliance with ASTM A276.
Confirm the logistics details, including lead time, which can vary for forged components due to custom sizing and heat treatment processes. Typical lead times for forged ring gears range from 4 to 8 weeks, depending on quantity and complexity. Clarify the Incoterms (e.g., FOB Jinan or CIF to your port) and payment terms, as these are not specified in the listing. For bulk orders, negotiate packaging and labeling requirements to meet your import regulations.
Quality checks should include dimensional verification of the outer diameter, inner diameter, and width to ensure they match your assembly tolerances. For gears, also inspect tooth profile accuracy and surface finish using a gear checker or coordinate measuring machine (CMM). Request a pre-shipment inspection report to confirm compliance with your specifications. Documentation such as material test reports (MTRs), heat treatment certificates, and packing lists should accompany the shipment for customs clearance and traceability.
