The details of stainless steel welding wire ER307

Mar 06, 2020

Specification/Clas.Code

AWS A5.9EN ISO 14343-A
ER307(mod)G 18 8 Mn

Properties & Application

  • GMAW solid wire of type G 18 8 Mn/ER307 designed for numerous appliactions.

  • The weld metal offers exceptionally high ductility and elongation together with outstanding crack resistance. There is on fear of embitterment when operating down to service temperatures of -110 or above +500,the scaling resistance goes up to +850(air)

  • The weld metal can be post weld heat treated without any problems, the deposit will work harden and offers good resistance against cavitations. Ductility is good even after high dilution when welding probelms steels or when subjected to thermal shock or scaling. Very good feeding,welding and wetting characteristics.

Base Metals

  • For fabrication,repair and maintenance.

  • Dissimalar joints,tough buffer and intermediate layers prior to hardfacing 14%manganese steels, 13-17% chromium heat resistance steels up to +850, armor plates, high carbon and quenched&tempered steels, surfacing of gears, valves,turbine blades etc.
