Oferta
HYW E309L-16 is an all-position stainless steel stick electrode (SMAW) designed for joining dissimilar metals and for overlay work. It welds stainless steel to carbon or mild steel, joins 309/309S base metals, and produces sound buffer layers and cladding. The extra-low carbon deposit guards against intergranular corrosion.
Key Features
- › AWS A5.4 classification E309L-16
- › Extra-low carbon (≤0.04%) for resistance to intergranular corrosion
- › Ideal for dissimilar-metal joints (stainless to carbon/mild steel)
- › Rutile coating — smooth arc, easy slag removal, clean bead
- › All-position welding on AC or DC electrode positive (DCEP / DC+)
Ideal Applications
- › Joining stainless steel to carbon or mild steel
- › Surfacing, cladding, and buffer / buttering layers
- › Welding 309 / 309S stainless and heat-resistant fabrications
