Sell welding flux ZT.HJ107

Description

ZT.HJ**7（**1）(NO Manganese-oxide welding flux) In accordance with GB/T*********9                   F***-H0Cr2lNil0                   F**8L-H*0Cr2Ni*0   DESCRIPTION:      ZT.HJ**7（**1）is a fused type no manganese-oxide flux with pumiceous granule of bluish gray to dark gray color, about ****0 mesh in size. This flux is designed for welding of auste-nitic stainless steel and is of characteristics with less carbon increment and less chromium loss.   APPLICATIONS:    This flux is recommended to use with H0Cr*1Ni*0, H0Cr*1Ni*0Ti, H0Cr*4Ni*2Nb,,H*0Cr*1Ni*0Nb、H*0Cr*6Ni*2、H*0Cr*1Ni*0 wires and strips doe welding of stainless steel and anti-corrosion cladding of nuclear pressure vessels and petrol chemical installations. It is also used for repair welding of high welding of high manganese steel with H0Cr*6Mn*6 wire. For welding of niobium stabilized stainless steel, the flux of LH.HJ**7Nb may be selected to solve the problem of difficult removal of welding slag.   TYPICAL PROPERTIES OF CLADDING LAYERS:    Being matched with H*0Cr*6Ni*2(first layer) and H*0Cr*1Ni*0(surface layers)welding strips for cladding on *0mm thick ISMnMoNb steel. 1. Carbon increment≤0.*1% Chromium loss≤1.5% 2.   After sensitization treatment, the specimen has passed the intercrystalline corrosion test in accordance with GB***4.*****0《 Method of corrosion test by sulfuric acidc-opper sulfate for stainless steel》   GUIDELINES FOR USAGE: 1.Dry the flux at **0℃ for 2 hours before use. 2.Completely remove rust, oil and dirt from the groove surface prior to welding.   TYPICAL FLUX COMPOSITION RANGE(%) SiO2+AI2O3 CaF2 MgO+CaO S P ****4 ＜*6 ****6 ≤0.*6 ≤0.*8   TYPICAL CHEMICAL COMPOSITION AND MECHANICAL PROPERTIES OF DE-POSITED METAL Flux & Wire ination Chmical composition of deposited metal(%) Mechanical properties C Mn S P Si Cr Ni ób MPa ō5 % HJ**7+H0Cr*1Ni*0 0.*5 1.*3 0.*1 0.**0 0.*1 *8.*7 9.*3 **3 *9.2
