AWS ER5.9 ER307Si produces a tough, ductile, 19% Cr / 9% Ni / 7% Mn austenitic stainless weld metal which is highly crack resistant. It is intended for joining hardenable steels, armour plate, 13% Mn steels and difficult-to-weld steels, without the need for preheating. It is also recommended for dissimilar joints between stainless and mild or medium carbon steels.Buffer layers on 13% Mn steels used in rock crushing and earth moving equipment, prior to hardfacing. Reclaiming 13% Mn steels. The surfacing of rails, rail crossings, frogs etc. Buffer layers in highly restrained repair work.

AWS A5.9 ER307Si
Dissimilar Welding: Suitable for welding between steel and stainless steel.
Buffer Layers: Can be used to deposit stress-relaxing buffer layers on crack-sensitive metals.
Precision Layer Wound: Ensures smooth and consistent wire feeding.
Austenitic Stainless Steel: Contains a significant amount of manganese, resulting in a predominantly austenitic weld metal.
High Mechanical Strength: Offers excellent crack resistance.
Silicon Content: The increased silicon content ensures weld pool fluidity, resulting in a smooth deposit appearance.
