Dynalloy

HARDBANDING
Dynalloy Industries offers a robust product line of welding, hardfacing and hardbanding wires. Each product has been specifically formulated to provide Wear Resistance, Corrosion Resistance, Toughness, or other specific characteristics.

POSTALLOY© TUFFBAND© NC

Postalloy© Tuffband© NC is a high hardness hardbanding wire that may be used by itself for casing friendly hardband applications or used as a weld matrix with Tungsten Carbide (WC) when casing protection is not a factor.

POSTALLOY© DURABAND© NC

Postalloy© Duraband© NC is a 100% crack-free hardbanding wire that provides maximum protection of the tool joint and casing. It’s microstructure consists of a hard, but tough tool steel matrix with a high volume of tightly packed micro-constituents. This combination ensures excellent wear resistance in open hole drilling as well as being casing friendly. Duraband© NC is unique. It is *Fearnley Procter NS-1TM Certified for new applications and it is the only product to be certified for re-application over itself and certain other products. It is the only product for maximum protection that is applied crack-free.

ER70S-2 Carbon Steel Welding Wire

 

ER70S-3 Carbon Steel Welding Wire

ER70S-3 is a premium mild steel solid wire, with silicon and manganese levels suitable
for general purpose welding over clean to light levels of rust and mill scale. ER70S-3
has the flexibility to provide trouble-free performance in heavy-duty, high-speed spray
or pulse applications to lighter duty, lower speed short-arc applications. ER70S-3 is
designed for use with various gas mixtures such as 100% CO2 ,75/25 Ar/CO2 or 98/2
Ar/O2. Even in the most difficult applications ER70S-3 produces a smooth stable arc
with low spatter, producing a weld bead that ties in evenly with the sides and has a
smooth finished appearance.

ER70S-6 Carbon Steel Welding Wire

ER70S-6 is a premium mild steel solid wire formulated to provide high quality welds
and trouble-free performance from heavy duty, high speed, spray transfer applications all
the way to light duty low speed, short-arc applications. ER70S-6 is designed for use with
various gas mixtures such as 100% CO2 ,75/25 Ar/CO2 or 98/2 Ar/O2. Even in the most
difficult applications ER70S-6 produces a smooth stable arc with low spatter, producing a
weld bead that ties in evenly with the sides and has a smooth finished appearance.

POSTALLOY© TOOL JOINT

Postalloy Tool Joint BU SA is a premium
medium manganese, carbon steel metal cored
wire for submerged arc welding with a very
smooth arc transfer.

Application

Hardbanding deposits are NON CRACKING, providing proper preheat, interpass and cooling temperature procedures are followed. The microstructure consists of a hard, but tough tool steel matrix with approximately 55Rc hardness. Deposits are extremely CASING FRIENDLY. Tuffband® NC can be applied over itself without removal, but only if the surface has been properly cleaned and inspected. Tuffband® NC can be applied over certain previously hardbanded competitive products providing that the worn deposit is 1/32” thick or less.

Application

DURABAND® NC microstructure consists of a hard, but tough tool steel matrix with a high volume of tightly packed micro-constituents. This combination ensures excellent wear resistance in open hole drilling as well as being CASING FRIENDLY. Typical hardness values of 57-60Rc can be expected when applied to new tools or properly rebuilt joints. Deposits are smooth and free of any slag. DURABAND® be applied over itself and over TUFFBAND® NC without removal, but only if the surface has been properly cleaned and inspected. Duraband NC can be applied over some competitive hardband products without removal.

Application

This wire is intended for multi-layer build-up of oil drilling tool joints, where compatibility with higher carbon steel chemistries is critical. Modern manufacturing technology ensures the best consistency, in both weldability and feedability. The cleanliness of Postalloy Tool Joint BU SA contributes to low subsurface porosity, and the elimination of lack of fusion or “cold laps”. Deposits are crack-free, can be readily machined with high speed and carbide tools, and can be flame cut or plasma cut.
