Stainless steel continuous & cut length solid welding wire for MIG/TIG welding
CLASSIFICATION : AWS/SFA-5.9 ~ER307; EN ISO 14343 18 8 Mn
CHARACTERISTICS :
ER307 is Manganese-austenitic Stainless steel grade is suitable where high standards of toughness and cracks resistant have to specially meet. It is suitable for MIG/TIG/SA welding. The high silicon grade gives improved weld flow and weldability for smoother weld beads.
APPLICATION :
ER307 suitable welding for cladding of hardanable steels, armour plate, austenitic stainless, manganese wear steels and heat resisting steels upto 850°C. The grade is particularly suite for hard facing hot work steel, stainless valve steel and carbon steel items that must possess abrasion resistance to corrosion.
SHIELDING GAS :
welding with 100% Ar gas and/or Ar+1-5%O2 gas
