FONTA FN 312

International Standards:
AWS SFA 5.4 : E 312-16
DIN EN 1600 : E 29 9 R 12
DIN 8556      : E 29 9 R 23

Application & Properties:
FONTA FN 312 electrode produce a weld deposit of 28% Cr – 10% Ni with the highest tensile & yield strength of any stainless electrode. It is used to weld dissimilar steels, unknown steels, difficult to weld steels, abrasion resistant steels, high strength steels and for joining high temperature alloys to carbon or low alloy steels. FONTA FN 312 electrodes produce ductile, crack resistant, porosity-free weld
deposits. Can be also used for Mn steels, hardening steels, armour steels, spring steels, and as a wear resistant build-up and buffer layer for hardfacing.

FONTA FN 347

International Standards:
AWS SFA 5.4 : E 347-16
DIN EN 1600 : E 19 9 Nb R 12
DIN 8556      : E 19 9 Nb R 23

Application & Properties:
FONTA FN 347 are used to weld austenitic 18% Cr – 9% Ni stainless steels where maximum resistance to corrosion is required. FONTA FN 347 weld deposit contain Niobium (Nb) which prevents intergranular corrosion caused by carbide precipitation. Commonly used for welding AISI 304, 321 and 347 stainless steels in the textile and cellulose industries for joint-welding mechanical parts exposed to chemical attack. Also used in pressure vessels at chemical plants and oil refineries, dye works, and for sealing basis applications in acid, gas, water and steam valves and fittings.

FONTA FN 309Mo

International Standards:
AWS SFA 5.4 : E 309Mo-16
DIN EN 1600 : E 23 12 2 L R 12
DIN 8556      : E 23 13 2 L R 23

Application & Properties:
FONTA 309Mo was developed for welding 22% Cr – 13% Ni – 2.5% Mo stainless steel, austenitic stainless steel containing molybdenum to mild or carbon steel and for welding ferritic steel plates clad with AISI 316 stainless steel. This electrode yields an austenitic ferritic, crack resistance against sulfuric acid, phosphoric acid, etc. It is typically used for overlaying carbon steel giving weld deposits analogous to 316 stainless steel.
