Product Description

Product Description

Exothermic Welding Powder Submerged Arc Welding Flux for High Speed Welding

Description:
HJ251 is a type of fused flux with low Mn,medium Si and medium F content,light yellow to light greenpumiceous grains in appearance.Its grain size is 10--60meshes.It adopts DC power supply,and thewelding wireis connected to the positive electrode,and the welding process performance is good.

Conforming to:GB/T12470-2003 F48A0-H10Mn2

Usage:
Combining with Cr and Mo steel wires,HJ251 can weld pearlitic heat-resistant steel,such as weldingsteam turbine rotor.It can also be used for welding other low alloy steels.
