FONTA FN 350
International Standards:
DIN 8555: E 1-UM-300
Application & Properties:
FONTA FN 350 is a general purpose hardfacing electrodes of medium hardness, which can be machined by chip-forming. Particularly suited for wear resisting parts subjected to heavy impact and shock. Can be used in all positions, except vertical-down. Weld metal is crack resistant and free of pores. Suitable for: Reconditioning of rails, rail crossings, switch points, sprockets and wearing parts, such as: rope pulleys, tumblers, rollers, caterpillar track rollers and links, wheel flanges, stud links.
FONTA FN 600
International Standards:
DIN 8555: E 6-UM-60
Application & Properties:
FONTA FN 600 is a hardfacing electrodes for depositing tough and heavy impact & shock resistance. It can be machined only by grinding. Only in case of very crack sensitive base metals, a tough buffer layer, made with FONTA FN 307 or FONTA FN 37 electrodes, is required. Suitable for: hardfacing excavator parts, bucket edges and bucket teeth, drilling bits, coal planes, conveyor screws, polygon edges,crusher jaws and cones.
FONTA FN 1000
International Standards:
DIN 8555: E 10-UM-60R
Application & Properties:
FONTA FN 1000 is a hardfacing electrode depositing hypereutectic chromium hard metal. It is suitable for producing highly wear resisting deposits subject to abrasion by mineral particles. The weld metal is machinable only by grinding. On difficult to weld steels, a buffer layer made with FONTA FN 307 or FONTA FN 37 electrodes is required. FONTA FN 1000 produces very smooth weld beads with flat penetration. Weld metal recovery is approx. 160%.
FONTA FN Mn
International Standards:
DIN 8555: E 7-UM-200 KP
Application & Properties:
FONTA FN Mn is a manganese hardfacing electrode for wear resisting hard facing deposits. Weld metal will adopt high hardness by cold working. It is therefore particularly suited for parts which are subjected mainly to wear caused by heavy impact and shock. When building up various layers, it is good practice depositing a buffer layer with FONTA FN 37 or FN 307 weld metal. Suitable for: hardfacing and repair welding of wear resisting parts made of austenitic manganese steel, such as crusher jaw plates, crusher cones, pulverizing hammers, beating arms and others.
FONTA FN SM
International Standards:
DIN 8555: E 10-UM-60
Application & Properties:
FONTA FN SM is an electrode for hardsurfacing rollers in sugar mills. Restrikes automatically even on wet base materials, allows to deposit efficient shaped dots, good weld bead aspect even at high travel speed, 200% recovery. Suitable for: mill rollers and roller flange in sugar manufactories.
