Product Detailed
GUIDELINES FOR USAGE: 1.Dry the flux at 250aa for 2 hours before use. 2.Completely remove rust, oil and dirt from the groove

ZT.SJD18 (welding flux)

DESCRIPTION:   ZT.SJD18 is a kind of F-basicity slag-series agglomerated flux, Its basicity is 2.0, and its size of whitish grain is 10-40mesh. By matching with flux wire 1Cr13, 2Cr13, 3Cr13etc for surfacing welding, there is no C increment and less Cr loss. It has smooth welding bead with good slag removal specially at high temperature. The smooth welding parts leaves no dots or other flaw, so it is suitable for the submergedarc surfacing welding of hot roller, The surfacing layer has high hardness, anticorrosion. By matching with H00Cr21Ni10,H00Cr19Ni12Mo2 wire, it can be used for the welding of super low carbon stainless steel and heat-resisting steel, surfacing Layer-hardness HRC ≥45. GUIDELINES FOR USAGE:1. Dry the flux at 300-350°C for 2 hours before use.2. Completely remove rust, oil and dirt from the groove surface prior to welding. TYPICAL FLUX COMPOSITION RANGE: (%)
