HF350R
EN 14700 : E Fe1
JIS Z3251 : DF2A-350R
Description：
HARDFACING 350R is a rutile type, AC/DC electrode which is recommended for the multi-layer build-up and surfacing of steel components subjected to metal-to-metal wear and compressive loading. It deposits an air hardening & machinable C-Mn-Cr steel alloy which is machinable. Typical applications in build-up and surfacing of gears, shafts, rollers, quarry parts, track links and etc.
Diameters:
3.2mm, 4.0mm, 5.0mm
