Stainless steel continuous & cut length solid welding wire for MIG/TIG welding
CLASSIFICATION :TAWS/SFA-5.9: ER307 (Nr.), BS 18.8Mn
DIN 8556: WK. 1.4370
CHARACTERISTICS : ER307 is Manganese-austenitic Stainless steel grade is suitable where high standards of toughness and cracks resistant have to specially met. It is suitable for MIG/TIG/SAW. The high silicon grade gives improved weld flow and weld ability for smoother weld beads.
APPLICATION : ER 307 suitable welding for cladding of harden able steels, armor plate, austenitic stainless, manganese wear steels and heat resisting steels up to 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 Or Ar+2%O2 gas.
