HF-N Basicity index: 2.6

Characteristics and Applications: HF-N is a neutral agglomerated fluoride-basic SAW flux for hard surfacing. During welding, it acts neutral in the all weld metal composition as a result of a large change in the arc voltage, and thus the arc length. HF-N has excellent hot slag removal especially when weld metal contains alloys such as Nb or V. - Continuous Caster Rolls

Notes on usage: 1. When the flux has been affected by moisture pick up, it has to be re-dried at a temperature of 350째C for 1 hour. 2. Adding proper quantity of new flux with the used one to maintain good quality of weld metal.

Notes on usage: 1. Be careful not to change the depth and temperature of the slag bath rapidly. 2. In order to prevent the interruption of welding. Check that adequate amounts of material are on hand before starting work. 3. When assembling weldments, please proceed with spot welding at the out side of the hole on metal parts. 4. Please keep gap precision less than 0.5mm. 5. Please remove all contaminations in holes and keep dry before welding. 6.

TF-R85 An agglomerated flux for SAW Characteristics and applications: TF-R85 is a basic agglomerated flux for SAW. During welding, it wonâ&#x20AC;&#x2122;t result any significant changes composition of weld bead and thus the arc length by changing arc voltage. This makes TF-R85 very suitable to use with wire for hardfacing applications. The weld bead has good appearance and excellent slag detachment. - Hardfacing applications - Low impurities - High hot crack resistance. - With wires: TWH- 12-S, 17-S, 31-S, 41-S, 45-S, and TWS- 410-S, 410NiMo-S, 420-S

Notes on usage: 1. Dry flux at 300~350 for one hour if there is any concern about moisture pick-up while opening the pack. 2. Add reasonable amount of new flux when recycled flux is used.

TFS-300

EN760 SA FB 2 AC

Basicity index: 2.4

Characteristics and Applications: TFS-300 is a neutral agglomerated flux, which has good weldability, excellent slag removal and smooth bead appearance. Some alloys were suitably added to maintain the stability of the alloy content in weld metal. It performs a very sophisticated mechanical properties and corrosion resistibility. - Stainless308, 308L, 316 and 316L butt join. - Pressure vessel

Notes on usage: 1. Use low heat input to keep the corrosion resistibility and mechanical properties on heat-affected zone unchanged. 2. Bake at 350 for one hour before use. 3. Add reasonable new flux when recycle the used flux so as to maintain good welding quality.

TFS-303 Characteristics and Applications: TFS-303 is a fused type of flux for various applications. It is designed primarily for SAW of 5%, 9%Ni alloys and joining of dissimilar base metals. Good results can be achieved when welding pipes and steels in combination with appropriate (TW-17/TW-61) wire electrodes. - 5% & 9%Ni alloys - Pipe or plate join

Notes on usage: 1. Drying the flux at 150 ~250 for 1 hr if moisture pick-up of flux is suspected. 2. Adding proper quantity of new flux with the used one to maintain good quality of weld metal. 3. While using TW-61 or TW-17 as combination, keep the inter-pass temperature under 100 .

TFS-330 EN760: SA AF 2 DC

Basicity：：2.0

Characteristics and Applications: TFS-330 is designed for both butt and fillet welding applications. TFS-330 behaves neutrally with regard to carbon content in the filler wire. The metallurgical behavior of the flux in respect to silicon and manganese is also neutral and as a result there is minimal burn out or pick up of these elements. The resultant weld bead is free from slag residue and requires little or no post weld dressing. Grain size according to DIN EN 760 2-20. - For submerged arc welding of the 300 series stainless steels, especially for 347 & 2209 - Applied to chemical plants, offshore, pressure vessels, storage tanks, power generation constructions, etc.

Notes on usage: 1. Any flux exposed to atmosphere for an excess period must be re-baked at 300-350

for 1 hour.
