WD-612 Agglomerated Flux For S.A. Welding
Standards: GB/T 17854-1999 F309-H0Cr24Ni13 F308L-H00Cr24Ni13
Introduction
WD-612 is an agglomerated calcium-silicate type flux with a basicity index of BIIW 1.0.Matching low-carbon and extra-low-carbon stainless solder strip,WD-612 can be used for band arc hard surfacing in the stainless steel transition layer of low-carbon and low-alloy steel. In order to prevent the excess burn-out of chromium, a certain amount of chromium should be contained in the welding flux as a supplement of the burn-out.
Applications
Band arc hard surfacing in the stainless steel transition layer of the inner wall and pipe plate of pressure vessels for the chemical industry and hydrogenation reaction chamber.
Main Constituents (%)
Typical chemical composition of deposited metal (%)
Notice:
1. Flux should be redried at 300~350°C for 2 hours.
2. All dust, oil and rust should be removed.
