Ductile Crack-Free Deposit for Mn Steel Build-up
High efficiency electrode with special coating, to resist massive impact by mineral or metal along with moderate to good resistance to mineral abrasion.
 
Despite the common tendency of cracking in manganese steel, this high purity bead remains ductile and crackfree even after die penetration tests.
 
The alloy also shows reluctance to necking in tensile specimen. In abrasion area also it is superior to all the above except high-density pre-formed carbides.
 
ALLOY BASE
Fe, Mn, Ni
 
SPECIAL FEATURES
  • Ripple free deposit
  • Auto slag detachment, free from slag inclusion
  • Low heat input even at high current capacity
APPLICATIONS
Crushers, earthmoving equipment, hammers, shovel track pads, wear plates, building up manganese steel components, buffering before carbide hardfacing deposit.
