ESAB 550
 
Super Hot Hardness and Edge Retention
A basic coated hardfacing electrode giving a weld deposit suitable for rebuilding of hot working tools, forging tools etc. Intended for hardfacing of hot trimming blades, hot bar shears etc. Resistance to scaling and tempering is upto 600°C.
 
The weld-metal gives extremely good spalling resistance, hot hardness due to grain boundary pinning by fi ne carbides.
 
ALLOY BASE
Fe, Cr, Mn, W, V, Mo, Co
 
SPECIAL FEATURES
  • Weld metal is resistant to scaling upto 600°C
  • The weld deposit gives extremely high secondary hardening
  • An excellent edge-retention property for repairing cutting and shearing tools
APPLICATIONS
Highest metal-to-metal wear resistance in upto 500°C along with good impact resistance. To be used where cutting, shaving, and piercing proprieties are required to be maintained.
 
Typical applications are shear blades, roll face repairs, tools for hot trimming and cold punching, lifting tongs for billets, high-speed steel dies and tools.
