Import 904l 316l Urea Grade Stainless Steel Bar — Buy in wholesale FOB from Supplier in China

Jiangsu Steel Group Co., Ltd. offers 904L and 316L urea grade stainless steel bars, austenitic grades engineered specifically for urea fertilizer synthesis and aggressive chemical processing. The bars are produced with controlled carbon, sulfur and phosphorus levels to prevent catalyst contamination in urea plants, with diameters normally ranging from 2.5 mm to 180 mm and lengths from 2 m to 6 m or per customer requirement. Each heat number and batch undergoes chemical and mechanical testing, with supply conforming to SUS, AISI, JIS, GB or DIN standards depending on project specification.

The 904L variant provides exceptional resistance to sulfuric acid and chloride pitting due to its high nickelMolybdenum and copper content, while 316L offers a cost-effective solution with adequate corrosion resistance for less extreme urea process stages. Both grades are delivered in milled, bright or pickled finish, with typical austenitic microstructure ensuring good formability and weldability for machined components. The controlled chemistry, particularly sulfur below 0.015 percent typical for urea grade, minimizes the risk of stress corrosion cracking in ammonium carbamate environments.

These bars are used to produce screws, nuts, engine components and structural fasteners for urea reactor internals, high-pressure piping supports and pump shafts in fertilizer complexes. Buyers are typically EPC contractors, urea plant operators and chemical engineering procurement teams sourcing for greenfield and retrofit projects. The supplier ships in seaworthy bundles of 500 kg with strong plastic wrapping, wooden case options and galvanized steel wire strapping, though exact MOQ, lead times and Incoterms should be confirmed directly with Jiangsu Steel Group given the zero percent response rate on record.

Jiangsu Steel Group Co., Ltd. maintains its registered address at 10/F, No. 257 Siping Road, Shanghai 200080, Hongkou, China, placing its commercial operations within Shanghai's steel trading district rather than necessarily at a production site. The supplier holds an imported tier classification and harbor trust tier, which indicates a verified import-export registration without implying third-party audited quality certification. The zero percent response rate and zero average response hours suggest the listing has not generated documented buyer engagement through platform channels, so direct contact via the Shanghai address or alternative channels is advisable for procurement discussions.

The supplier's product scope spans multiple stainless steel families from 200 series through duplex grades, with urea grade 316L and 904L positioned within its special steel offering. No information is provided about mill origin, ISO 9001 or ISO 14001 certification status, annual capacity, or specific end-user references in the urea sector. Buyers should request mill test certificates, verify material traceability to heat numbers, and confirm whether the supplier operates as a trader, mill agent, or direct manufacturer before committing to specification-critical urea grade orders.
