Sandvik 16.5.1 (Welding wire)
Datasheet updated 2012-08-02 19:38:11 (supersedes all previous editions)
Sandvik 16.5.1 is a filler material for joining EN 1.4418 and similar steels. It is also used for overlay welding. The weld metal has excellent resistance to cavitation and is used typically for shafts, propellers, pumps and valves in for example, in hydropower generation. Sandvik 16.5.1 is available as wire and rods for MIG/MAG, TIG, plasma-arc and submerged-arc welding.
Chemical composition- filler metal
Chemical composition - all-weld metal
The following data is typical for non heat treated all-weld metal made by MIG or TIG welding with argon shielding gas.
The following data is typical for non heat treated all-weld metal made by SAW and flux 15W.
Microstructure - all-weld metal
Martensitic-austenitic microstructure with a ferrite content of 12 FN.
Mechanical properties- all-weld metal
|Yield strength, RP0.2||MPa||470|
|Tensile strength, Rm||MPa||850|
|Impact strength, Charpy V||J||80|
|Yield strength, RP0.2||MPa||490|
|Tensile strength, R||MPa||850|
|Impact strength, Charpy V||J||40|
Corrosion resitance - all-weld metal
The weld deposit is resistant to scaling in air up to 850 °C (1560 oF). Its pitting and general corrosion resistance is comparable to EN 1.4306, AISI 304.
Recommended welding data
Electrode positive is used to give good penetration in all types of welded joint. The following table shows common conditions for MIG welding.
|Wire diameter, mm||Wire feed, m/min||Current, A||Voltage, V||Gas, l/min|
1)Pulse parameters: Peak current 300 - 400 A
Background current 50 - 150 A
Frequency 80 - 120 Hz
Short-arc welding is used with light gauge material of less than about 3 mm, in depositing root runs, and in welding out-of-flat positions.
The higher the inductance in short-arc welding, the higher the fluidity of the molten pool.
Spray-arc welding is normally used for heavier gauge material.
The parameters for TIG welding depend largely upon the base metal thickness and the welding application.
Electrode negative and a shielding of argon or helium should be used to prevent oxidation of the weld metal. Read more about shielding the weld.
Electrode positive is suggested for joint welding to give good penetration.
