DIN BFB165AC12MHP5
Product Description
Semi-Basic, agglomerated flux specializing for X60-X70 degree pipe material welding.
Product Feature
Adopts AC/DC. The wire is connect to the positive rod when DC. It has nice welding technic performance property with steady electric arc, and the features of good slag detachability, and nice welding line configuration.
Product Specification
- Flux type: Fluoride
-Basic- Basicity index: 1.8
- Grain size:2.0-0.4mm(10-45meshes)
Application
Matching proper wire(H08C,H08MnA,H10Mn2,H08MnMoA,H08Mn2MoA) can be used for pipe steel such as X52,X60,X65,X70. It can be applied to multiple-layer welding, double-face single way welding, multi-wire and SAW in a narrow clearance.

Remark
1. Before welding, fluxes should be baked for two hours at 300-350℃.
2. Removal of rust, oil, dirt, water, impurities, etc in welding-areas.
