Description and Applications: Description and Applications:
• Rutile coated high recovery stainless steel electrode • Basic coated electrode for welding austenitic
• For welding 14% Mn steels, mixed joints between stainless Cr-Ni steels
high alloyed steel, stainless steels and unalloyed • Suited for positional welding of thick plates and highly
base materials restrained joints
• Used for hard to weld steel joints and buffer layers in • Excellent resistance to cold cracking
hardfacing applications • Good mechanical properties
