EnDOtec DO*351 Flux-cored wire Ø 1,6mm

EnDOtec DO*351

Seamless alloyed flux-cored wire electrode for gas-shielded arc welding, ideal for series production or maintenance and repair applications where absolutely perfect welding results, efficiency and productivity are required.
High-alloy CrSiC steel for wear-resistant coatings. The air-hardening weld metal offers excellent resistance to wear caused by impact/impact, friction (metal on metal)
and abrasion. The forgeable weld metal can be heat-treated or nitrided and is resistant to thermal shock.
Excellent arc stability.
Low heat input for low melting.
Exceptionally good weldability regardless of the welding position.
Uniform weld bead profile, virtually no spatter.
Versatile over a wide range of parameters.
Lower labor costs due to higher deposition speed.

Technical data
DIN EN 14700: T Fe 8
Hardness: 57 - 62 HRC

Applications
Specifically for coatings to protect against wear caused by impact stress, friction (metal on metal) and abrasion in various industrial sectors, e.g:

• Mining and quarries
  Drill heads, crusher plates, crushing rollers, conveyor buckets and drag shovels
• Construction industry
  Gravel pumps, rails, jaw crushers, buckets/teeth, tracked vehicles
• Household and industrial waste disposal
  Grates and frames of crushing components, hydraulic presses.

Processing instructions
Completely remove old weld metal residues and worn metal by grinding or with ChamferTrode 03/04.
The preheating requirement depends on the CEV value of the steel and the size, thickness and shape of the workpiece. Castolin Eutectic recommends:

• CE < 0.2 : Preheating not absolutely necessary
• CE 0.2-0.4 : Preheating to 100 - 200 °C.
• CE 0.4-0.8 : Preheat to 200 - 350 °C.

Note: Never preheat 12-14 % Mn steels and ensure that the temperature of the workpiece is always below 250 °C during welding.
