RAAJMIG ER307 (AWS A5.9 ER307)

Product Specification

Stainless steel continuous & cut length solid welding wire for MIG/TIG welding

CLASSIFICATION          : AWS/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/SA welding. The high silicon grade gives improved weld flow and weldability for smoother weld beads.

APPLICATION               : ER 307 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 Or Ar+2%O2 gas.
