Application\/properties:<\/strong><\/p>\n\n\n\n

Eectrode for welding of dissimilar steels and for surfacing purposes. The weld metal consists of austenitic Cr-Ni-steel with possible small amounts of delta-ferrite; it is non-scaling up to 850\u00b0C. It features high resistance to cracking and is therefore indicated for difficult-to-weld steels and depositing stress-relaxing buffer layers on crack sensitive base metal or beneath hard-facing deposits. Highest temperature of dissimilar steel joints is +300\u00b0C; at higher temperatures AMA 1604G electrode shall be used. Weld metal will work harden.<\/p>\n\n\n\n
