MIG 309LSi (G 23 12 LSi,ER309LSi) 0,8mm 15kg/db hőálló acélokhoz és átmeneti, vegyes kötésekhez huzal Elga Cromamig (98052008)
Leírás
Cromamig 309LSi deposits a 23% Cr / 13% Ni austenitic stainless steel weld metal with a ferrite
content of about FN 11. The high alloy level and high ferrite content enables the weld metal to tolerate
dilution from carbon and low alloy steels without hot cracking. The higher silicon content gives
better arc stability and weld metal flow which improves bead appearance, particularly when dip
transfer welding.
APPLICATIONS:
– Buffer layers on mild and low alloy steels prior to overlaying with MIG/TIG 308L.
– Joining of clad steels and dissimilar joints between stainless and mild or low alloy steels.
– Welding of similar composition, 309L type, stainless steels.
– Joining of ferritic-martensitic stainless steels.
Welding current:
DC+
Shielding gas:
M12, Ar + 2% CO2, 16-21 l/min
M13, Ar + 1-3% O2, 16-21 l/min
Approvals:
TüV
Mechanical properties
Typical
Yield strength, Rp0.2%: 450 MPa
Tensile Strength, Rm: 650 MPa
Elongation, A5 35%
Impact energy, CV: 20°C • 130 J
–120°C • 60 J
Ferrite content:
