RAAJMIG ER307 (AWS A5.9 ER307)

Product Specification

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

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
