UTP HydroCav - UTP Schweissmaterial

Standards :
DIN 8555 : MF 4-GF-55-ST
EN 14700 : T Fe8
Open-arc flux cored wire for highly
wear resistant surfacings
Application field
The self-shielding open arc wire SK 258-O is universally used for build ups on parts subject to a combination
of pressure, impact and abrasion.
Earthmoving equipment, bucket knives, surface protection on buckets, mill hammers, conveyor screws,
shredders, percussion tools, coal plain. Machining is only possible by grinding.
Properties of the weld metal
SK 258-O is a martensitic alloy and especially suited for strong compression and impact strain.
Hardness of the pure weld deposit : 55 HRC

Welding instruction
Clean welding area. Preheating is generally not necessary, use dragging welding technique with approx. 25 -
30 mm wire stickout.
