Launch of Small-Spool, Fine-Diameter Stainless Steel Flux-Cored Wires

CHANGZHOU, China – As 2022 drew to a close and China's COVID-19 control measures were gradually relaxed, Jiangsu Daxuan Welding Materials Co., Ltd. achieved another milestone in new-product development. Our 308L, 309L and 316L stainless steel flux-cored wires for thin-sheet applications, available in 1.0 mm and 1.2 mm diameters on small spools, were successfully introduced at a well-known Chinese automotive parts manufacturer.

The successful development of this product range strengthens Daxuan's ability to keep pace with steel-use trends in China's advanced manufacturing sector and positions the company to capture new opportunities in the premium welding wire market.

Stainless steel flux-cored wire is widely used in stainless steel fabrication. The clean, smooth appearance of stainless steel products, with barely visible joints, depends heavily on the welding wire. Among the available wire types, flux-cored wire is especially valued for its stable welds and smooth welding performance.

Many stainless steel applications involve thin sheets, which generally require fine-diameter wire. For welding 2 mm sheet, wire with a diameter of 1.0 mm or less is normally used at a current of 80-150 A to achieve good welding performance. A 1.2 mm wire is generally less suitable under these conditions.

Fine-diameter flux-cored wire is difficult and more expensive to manufacture than conventional 1.2 mm and 1.6 mm products. Daxuan brought its technical and production teams together to meet this challenge. After carefully designing the formulation, fine-tuning the manufacturing process and conducting repeated trials, the company successfully produced its 1.0 mm and 1.2 mm small-spool stainless steel flux-cored wire series.

The products offer excellent welding performance, low spatter, good bead appearance, easy slag removal and low porosity sensitivity. Their chemical composition and mechanical properties meet the requirements of GB/T 17853 and AWS A5.22.
