Import 308 Lsi Stainless Steel Bar — Buy in wholesale FOB from Supplier in China

308 LSI stainless steel bar from Jiangsu Steel Group Co., Ltd. is a low-carbon austenitic stainless steel grade with enhanced silicon content, specifically developed for welding electrode and filler wire applications. The material composition runs chromium 19-21%, nickel 9-12%, silicon 0.65-1.00% and carbon maximum 0.03%, giving it superior weld pool fluidity and reduced risk of weld cracking. The supplier machines this grade to GB, AISI/JIS, SUS, UNS and DIN 17440 / 17220 (BS970 Part 4) standards, with outer diameters from 1.0 mm to 400 mm and standard lengths at 3000 mm or 6000 mm, though custom lengths are available on request. Surface finishes include bright, pickled and black, while processing techniques cover forged, hot rolled, cold drawn and peeled methods.

The elevated silicon level in 308 LSI, compared to standard 308L, improves arc stability and minimises spatter during gas metal arc welding, a property valued in automated welding lines. In the typical industry context, 308 LSI filler metal is specified for joining 301, 302, 304, 308, 321 and 347 base metals, as well as for surfacing applications where matching corrosion resistance is required. The grade maintains adequate resistance to intergranular corrosion in the as-welded condition, provided heat input is controlled. Standard dimensional tolerances for cold drawn bright bar reach H9, which is typical for precision machining and shaft applications. The austenitic structure ensures non-magnetic properties in the annealed state and retains toughness at cryogenic temperatures.

Buyers sourcing this bar for welding consumable production, chemical plant maintenance stock or marine fabrication should verify the specific surface finish and tolerance class required for their downstream process. The petroleum, chemical, construction, textile, medical, aviation, aerospace, railway, highway infrastructure, landscape protection and metallurgical machinery sectors all represent confirmed end-use markets from this supplier's profile. Jiangsu Steel Group Co., Ltd. holds ISO9001 certification according to the source data. Response rate stands at 0.00% with zero average response hours logged, so direct follow-up through the listed Shanghai address at 10/f No.257 Siping Road, Hongkou, is advisable for urgent enquiries. Standard seaworthy packing in plastic and wooden packaging is offered, with custom packing available on request.

Jiangsu Steel Group Co., Ltd. is headquartered at 10/f No.257 Siping Road, Shanghai 200080, Hongkou District, China, operating as an imported-tier supplier with harbour trust classification on this marketplace. The supplier's profile indicates a broad stainless steel bar manufacturing programme covering grades from 201 through 430 series, including numerous low-carbon and silicon-modified variants such as 308 LSI, 309 LSI and 316 LSI that target welding and fabrication markets. Response metrics show 0.00% response rate and zero recorded average response hours, which suggests either a new listing, inactive account, or data tracking limitation that buyers should factor into their sourcing timeline.

The company holds ISO9001 certification according to its listed credentials. Its product range extends across seven bar geometries, multiple surface conditions and several processing routes, indicating vertically integrated mill capabilities rather than pure trading. The source data does not disclose production capacity, employee count, revenue figures, specific client names or year of establishment. Buyers should request recent mill test certificates, third-party inspection reports and current production schedules directly from the supplier's Shanghai office before committing to volume orders.
