Stainless Steels Manual Electrode E2553-15 MJHS ethylene glycol synthesis tower welding goods
WELDING TECHNOLOGY
Don't let the questions
Continue to haunt you
Arc instability
Unsightly molding
Excessive spatter
Suitable for welding of 25% Cr duplex stainless steel,
such as 0 ocr25ni7mo4n,
03cr25ni6mo3cu2n,UNS 32550 (Alloy255), etc.
Duplex stainless steel is low hydrogen type electrode with the hand,
the main ingredient is 25.5% Cr Mo - 7.5% Ni - 3.5% - 2% Cu - 0.17 N
Ripple fine
With high strength and good resistance to pitting corrosion and stress corrosion cracking performance
Arc welding technology is excellent, stable, beautiful shape,
corrugated is exquisite, little splash, easy to take off the slag.
Easy slagging
