DIEWELD HARDNESS : 32-36 HRc
Size (mm) : 3.15 4.00 5.00
Current (amps) : 100-120 110-150 150-170
Newly developed low heat input electrode that gives a Cr-Ni-Mo- V alloy steel deposit
which is considered to be standard for die-block repairs, both patch work type as well as extensive.
The deposit has good machinability & gives improved die life, & hence it is the automatic choice for the
repair & reclamation of hot forging dies. As deposited hardness is 32 - 36 RC.
A post weld stress relief heating to 450º C for 1 Hr / 2 Hr would further improve toughness of repair work.
DIEBUILD N HARDNESS : 45-48 HRc
2 TENSILE STRENGTH : 100 -120 kgf/ mm
Size (mm) : 3.15 4.00 5.00
Current (amps) : 80-110 100-140 130-170
A basic coated electrode which deposits a rich Cr- Ni- Mo-V weld metal containing
lower carbon but otherwise similar to 55 Ni Cr Mo V2. It is excellent for building
up working face of composite hot forging dies, both large as well as small. The deposit has excellent
wear resistance at elevated temp. ( Upto 650º C ), It is eminently suitable
for the reclaimation of repairing all types of hot dies, equally useful for small patch work as well as extensive repairs.
DIEBUILD E HARDNESS : 41-45 HRc
2 TENSILE STRENGTH : 100 -110 kgf / mm
Size (mm) : 3.15 4.00 5.00
Current (amps) : 80-110 100-140 130-170
A basic electrode which is designed to give a low carbon alloy steel weld deposit similar to H 12 in its alloy content.
It is extemely suitable for building up large composite dies or extensive repairs of
similar insert dies used in hot-forging. The weld metal has an excellent
heat cracking resistance and resistance to thermal shock. It exhibits superior wear
resistance at high temperature as compared to DIE-BUILD-N.
The deposit is machinable & has a hardness of 41 - 45 Rc. Its hardness can be
controlled as desired by employingasuitable postweldheat treatment/tempering.
DIEBUILD S HARDNESS : 41-47 Rc
2 TENSILE STRENGTH : 100 -110 kgf / mm
Size (mm) : 3.15 4.00 5.00
Current (amps) : 85-110 100-130 130-160
Basic coated electrode of this series, gives a highly alloyed low carbon weld1 metal similar to BH 10 A.
The weld metal is machinable and exhibits a high degree of toughness, excellent hot strength
and wear resistance at elevated temperature alongwith good heat cracking resistance.
It stands up well against temperature shocks and even admits water cooling
from 500 º C to 650 º C. Suitable for building up large composite dies or extensive
repair of similar dies used in steel, chemical industry, as well as nuclear industry.
DIFFUSALOY DIE 100 TENSILE STRENGTH : 75 kgf/mm (Min.)
Hardness : 42 - 45 HRc
Size (mm) : 3.15 4.00 5.00
Current (amps) : 80-120 120-150 150-190
A newly developed electrode with Cr-Ni-Mo specially for forging die repairs in forging industry.
The deposited weld metal is highly resistant to cracking even with higher impact load.
It is an all position electrode with high strength for repair of large forging dies, hot working tools,
hammer bases, sow blocks anvil, devotails and insert dies, rolls of cold rolling mill.
Any surface requires impact and friction resistance.
DIFFUSALOY DIE 101 TENSILE STRENGTH : 115 kgf/mm (Min.)
HARDNESS : 37 - 42 HRc
Size (mm) : 3.15 4.00 5.00
Current (amps) : 80-120 120-150 150-190
A newly developed electrode with Cr-Ni-Mo-W-Co specially for forging die repairs in forging industry.
It is used for welding high-strength tempered low-alloy steels as well as process
welding on steels castings, cast steels of corresponding strength. It is an all position electrode
with high strength for repair of large forging dies, hot working tools, hammer bases,
sow blocks anvil, devotails and insert dies, rolls of cold rolling mill.
DIFFUSALOY DIE 105 Hardness : 47 - 54 HRc
Size (mm) : 3.15 4.00 5.00
Current (amps) : 80-120 120-150 150-190
A newly developed electrode with Cr-W-V used for similar type steel and also for overlaying
the edges or surfaces of tools made of low alloyed steels. Weld deposit have good high temperature
resistance which is very helpful in increasing the life. This product is very much suitable
for forging die repairs in forging industry. Used for hot shear blades,
drawing blocks, hot forging dies, impact moulding dies, slab shears, containers, swages etc.
