BÖHLER FOX EV 70伯乐焊条

Description
Basic coated Mo-Ni alloyed electrode exhibiting high ductility and crack resistant for applications on
high-strength fine-grained steels. Suitable for service temperatures between -60 °C and +350 °C.
metal recovery approx. 115 %. Easy to handle in all positions except vertical-down. Very low
hydrogen content ( according AWS condition HD ≤ 4 ml/100 g weld metal ).
Preheat and interpass temperatures, as well as post weld heat treatment as required by the
base metal.
