Arcostar 304L 3,2mm 4,2kg Elétrodo de soldadura em aço inoxidável E308L-16

The Arcostar 304L welding electrode is a high-quality stainless steel electrode designed for welding AISI 304L, 321, and 347 stainless steels. With a diameter of 3.2 mm and a pack weight of 4.2 kg, this electrode offers excellent corrosion resistance and a smooth, stable arc. It is suitable for all welding positions and operates on DC+ current.

Advantages

Low carbon content (<0.04%) ensures excellent intergranular corrosion resistance. Easy slag removal and smooth arc stability make it ideal for professional welders. The rutile coating provides a stable arc and minimal spatter.

Suitable for

• Welding of AISI 304L, 321, and 347 stainless steels
• All welding positions: flat, horizontal, vertical up, overhead
• Applications requiring high corrosion resistance
