UNIBRAZE® 1100

UNIBRAZE 1100 is the ultimate electrode for welding all types of steels, without any danger of cracking or breakage. Special "FERRITE BALANCED" Chemistry also allows UNIBRAZE 1100 to serve as a "STUD PULL" electrode. Due to exceptional strength and crack resistance, it is ideal for repairing tools, dies, spring steel and any dissimilar metal combinations, except for the aluminum and copper alloys. Also recommended for repairing worn parts and as an underlay for hardfacing.

Typical Deposit Characteristics
Tensile Strength 132,300 psi
Yield Strength 94,000 psi
Elongation % 36.0%
Hardness 320 HB

UNIBRAZE® Cast SM

UNIBRAZE CastSM is a solid core welding electrode for the welding of most cast irons, including gray cast iron and spheroidal graphite cast iron parts. With a unique non-nickel series core rod, the weld zone of the reclaimed part is almost indistinguishable from the parent material after welding. UNIBRAZE CastSM has an extremely smooth welding arc, and excellent slag fluidity. Weldability, crack resistance, as well as workability and mechanical properties are all excellent.

Typical Deposit Characteristics
Tensile Strength 84,000 psi
Elongation % 27.0%
Hardness 180 HB

UNIBRAZE® Cast DM

UNIBRAZE CastDM is a solid core welding electrode for the welding of most cast irons, including gray cast iron and spheroidal graphite cast iron parts as well as dissimilar metals (carbon steel, stainless). With a unique non-nickel series core rod, the weld zone of the reclaimed part is almost indistinguishable from the parent material after welding. UNIBRAZE CastDM has an extremely smooth welding arc, and excellent slag fluidity. Weldability, crack resistance, as well as workability and mechanical properties are all excellent.

Typical Deposit Characteristics
Tensile Strength 84,000 psi
Elongation % 27.0%
Hardness 180 HB

POSTALLOY® 14

POSTALLOY 14 is a self-fluxing, oxy-acetylene hardfacing alloy that is applied below the fusion temperature of the base metal. It may be used on carbon steels, alloy steels, nickel alloys and cast iron. POSTALLOY 14 flows out easily and may be applied in extremely thin layers. Deposits are non-sparking, non-magnetic, and non-heat treatable. Excellent cold and hot abrasion resistance - Maintains a high level of hardness up to 1200°F (649°C) . Outstanding for metal-to-metal wear resistance - Deposits take on an extremely high polish, and will resist galling and freezing when in contact with other metals. Good Corrosion Resistance - POSTALLOY 14 will provide corrosion protection that is equal to most stainless steels and Inconel alloys.

Typical Deposit Characteristics
Hardness (Room Temp) 59 Rc, (800°F) 55 Rc, (1000°F) 50 Rc, (1200°F) 45 Rc
Typical Application Properties**
Valve seats

POSTALLOY® 21

POSTALLOY 21 is a “self-hardening" wear resistant overlay engineered for abrasion and abrasion combined with medium impact. The alloy chemistry provides good resistance to spalling and chipping while the special low hydrogen coating minimizes dilution and helps to eliminate underbead cracking. Use on carbon and low alloy steels, It can be used out-of-position and can be used with all types of AC or DC equipment.

Typical Deposit Characteristics
Hardness 56-60 Rc
Deposit Thickness 2-3 passes
Deposits Non-machinable
Typical Application Properties**
Excavator parts
