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.
