More Details

HH-810 Hardfacing flux cored welding wire

Welding the hardfaced layer (build-up layer) of the grinding rollers (VRM) & press roller (HPGR)

Characteristics

HH-810 produces a wear-resistant, austenitic, primary carbide-containing weld deposit. It is very resistant to abrasion.

1. Microstructure: High-chrome-high-carbon hard alloy on iron base with molybdenum additions, C – Cr – Mo – Fe.

2. Machinability: Grinding only.

3. Cutting: Not suited for flame-cutting.

4. Deposit thickness: Multi layers.

Specification

EN14700 T Z FE 15g

Application

Recommended particularly for the hardfacing of parts subjected to strong abrasion and medium impact stress, e.g. Vertical mill rollers, Mill discs, Roll presses, Sieves, Stirrer blades, Sand slingers and Top coats of Dredger teeth. The application temperatures should not exceed 500℃.

Welding Precautions

When using HH-810 welding wire, do not use inert gas. During welding, carefully control the current and voltage according to the recommended surfacing parameters.
Both weaving and straight bead are possible. Multiple layers can be welded. The performance of the surfacing alloy layer is related to the surfacing dilution rate.
After each weld layer is completed, the weld slag must be cleaned before welding the next layer, and so on.
