Instruction and Application: H08CrMoA welding wire and flux SJ110 SJ110 alkali fluoride-type flux, rounded particles, particle size is 2.0~0.28mm (10~60mesh). Excellent welding properties and metallurgical properties. Impurities and diffusible hydrogen content in weld metal of low, good crack resistance, low temperature toughness, temper embrittlement sensitivity. Apply to the petroleum refining, petrochemical, power generation, nuclear energy and other equipment using ASME SA387Gr. 12 Class 2 (15CrMoR (H)) and welding materials. Suitable for narrow gap welding.

Mechanical properties of All-weld metal

*In practice, the heat treatment system shall be formulated separately by the supply and demand parties or by the conditions of the working conditions (such as the thickness of the specimen).

H_D (Mercury method): ≤ 4.0ml/100g

Physical and chemical analysis of the flux(％)

All-weld metal radio-graphic testing:

According to NB / T 47013.2, the radio-graphic detecting technique should not be less than class AB and the quality grade of all-weld metal should not be less than Class I.

Reference range (DC﹢)

Notice：

1.Redry the flux at 300-350℃ for 2 hours.

2.Cleaning the oil stain, rust and moisture of the weldment surface before welding.

3.Multi-pass welding must clean the welding slag. Each layer is controlled into 180℃ to 250℃.
