Stainless Steels Manual Electrode E347-15 Polypropylene reactor welding goods


WELDING TECHNOLOGY
Don't let the questions
Continue to haunt you

Arc instability

Unsightly molding

Excessive spatter
Often used in acid and heat resistant pressure vessels,
petrochemical and other important structures such as
1Cr18Ni9Ti(SUS321), 1Cr19Ni11Nb(SUS347).
The main composition of low hydrogen stainless steel hand electrode is 19%Cr-11%Ni-Nb

Ripple fine
Adding Nb on the basis of 308 can effectively
improve the resistance to intercrystalline corrosion
Excellent welding performance, excellent fire resistance,
good porosity resistance, stable mechanical properties of molten metal

Easy slagging
