ER309LSi
ARCSTEEL ER309LSi
Wire for joining stainless steels to mild and medium-tensile carbon steels.
Product Description
AWS A5.9 : ER309LSi
This flux-cored wire is designed for joining stainless steels to mild and medium-tensile carbon steels. Additionally, it is optimized for depositing intermediate buffer layers on structural steel substrates prior to cladding or overlaying with Grade 308 stainless steel.
Specifications
- The chemical composition yields a delta-ferrite content of approximately 12%, providing robust immunity against hot cracking.
- Elevated silicon levels enhance weld pool fluidity, ensuring an optimal bead profile and a smooth surface finish.
- Engineered also for joining clad steels, provided that operational service temperatures do not exceed 300°C.
