IV. Core Product Features
Easy Welding Operation: When used with flux, the weld forms smoothly, with no residue after slag removal. It delivers stable welding results for complex joints such as fillet welds, reducing subsequent cleaning costs.
Excellent Flux Compatibility: When combined with BOHLER BB 802 fluoride-basic agglomerated flux, it enables low flux consumption and produces low-hydrogen weld metal, avoiding hydrogen-induced cracking.
Wide Temperature Resistance Range: The weld can work stably in the temperature range from -195℃ (low-temperature working conditions) to +350℃ (medium-temperature working conditions), eliminating the need for frequent replacement of welding materials.
Strict Quality Control: The entire production process complies with the ISO9001-2008 quality management system and has passed dual certifications of CE and SGS, ensuring both compliance and reliability.
Flexible Customizable Packaging: In addition to the standard 1kg/5kg/15kg spool packaging, the packaging specifications can be adjusted according to customers' production needs to adapt to production scenarios of different scales.
V. Applicable Application Scenarios
Compatible Stainless Steel Materials: Specifically designed for austenitic stainless steels such as 1.4306 (304L), accurately matching the material characteristics.
