Abstract
This invention relates to a welding material of ferrite-austenite two-phase stainless steel capable of producing a weld metal having a high resistance to corrosion, particularly in an environment containing nitric acid, and the method of application therefor. The welding material consists essentially of not more than 0.03% of C, not more than 2.0% of Si, not more than 2.0% of Mn, 25 to 30% of Cr, 7 to 12% of Ni, not more than 0.35% of N, and the balance Fe and inevitable impurities. The Ni balance value given by the following formula ranges between -11.7 and -6.7:
