S-787TB x H-14

Classification:
AWS	A5.17/ASME SFA5.17 F7A(P)8-EH14

Description:

Single and multi-layer welding of aluminum-killed steel for low temperature service used in offshore structures, chemical vessels, steel pipes, low temperature service equipments, and other structures in cold regions. Excellent notch toughness at low temperature down to -60°C(-76°F). Suitable for single and multi-layer welding of TMCP steel. Resistance to pockmark and porosity are excellent. Slag detachability in the groove is good.

Mechanical properties:
Yield strenght	580 N/mm2
Elongation	31%
Tensile strenght	620 N/mm2
Impact strenght	90 J / -62ºC

Superflux 50ULT x H-14

Classification:
AWS	A5.17/ASME SFA5.17 F7A(P)8-EH14

Description:

Multi-layer welding of various kinds structure such as ship buildings, offshore structures, pressure vessels. It produces the weld metal which has excellent impact value at low temperature down to -60°C and CTOD at temperature down to -10°C. As the hydrogen content of weld metal is extremely low, it shows excellent resistance to crack. Tandem, multi-electrode can be performed. AC power source is recommendable because DC makes inferior quality.

Mechanical properties:
Yield strenght	530 N/mm2
Elongation	30%
Tensile strenght	580 N/mm2
Impact strenght	120 J / -62ºC

Superflux 787 x H-14 (H-14L)

Classification:
AWS	A5.17 / ASME SFA5.17 F7A(P)8-EH14

Description:

Multi-layer welding of various kinds structure such as ship buildings, offshore structures, machinery, pressure vessels. High-basic bonded type flux having excellent impact properties at temperature below to -60ºC and good CTOD. Tandem, multi-electrode welding can be performed. Owing to insensitivity to rust, scale, primer on the surface to be welded, has excellent X-ray characteristics and slag removal.

Mechanical properties:
Yield strenght	470 N/mm2
Elongation	26%
Tensile strenght	560 N/mm2
Impact strenght	130 J / -62ºC

Superflux 787 x H-12K

Classification:
AWS	A5.23/ASME SFA5.17 F7A(P)8-EH12K

Description:

Multi-layer welding of various kinds structure such as ship buildings, offshore structures, machinery, pressure vessels, large diameter and heavy wall steel pipe. An agglomerated fluoride-basic flux suitable for welded joints on high-tensile, fine-grained steels. Tandem, multi-electrode welding can be performed Owing to insensitivity to rust, scale, primer on the surface to be welded, has excellent X-ray characteristics and slag removal.

Mechanical properties:
Yield strenght	540 N/mm2
Elongation	32%
Tensile strenght	580 N/mm2
Impact strenght	168 J / -62ºC
