Use

For welding ASTM A387 Grade 92, P92/T92 steel, the weld metal exhibits excellent creep-rupture resistance.

Welding consumables for 9Cr–1Mo martensitic heat-resistant steel, producing weld metal with excellent creep-rupture resistance.

It is suitable for 2.25% Cr–1% Mo–V pearlitic heat-resistant steel, with weld metal exhibiting excellent crack resistance and low-temperature impact toughness, as well as low susceptibility to temper embrittlement.

Suitable for welding thick plates of ASTM A387 Grade 22 heat-resistant steel, the weld metal exhibits excellent crack resistance and low-temperature impact toughness, with low susceptibility to temper embrittlement.

Applicable to the welding of thick heat-resistant steel plates in accordance with ASTM A387 Grade 11, Class 1.

Welding of thick plates made of ASTM A387 Grade 11 CL1 and 15CrMoR heat-resistant steel.

Suitable for 0.5% Mo steel single- and multi-pass submerged arc welding.

Weld metal with excellent creep-rupture resistance, suitable for welding ASTM A387 Grade 91, P91, and T91 steels.

It is used for welding ASTM A3B7 Gr5 steel, resulting in weld metal with excellent crack resistance and low-temperature impact toughness, as well as low susceptibility to temper embrittlement.

Suitable for welding thick plates of ASTM A387 Grade 11 CL1 and 15CrMoR heat-resistant steel. The deposited metal exhibits excellent crack resistance and low-temperature toughness.
