Exaton 25.10.4.LB

Exaton 25.10.4.LB is a high‑alloy chromium‑nickel‑molybdenum‑nitrogen covered stick electrode with a basic coating, designed for welding 25 %Cr and super‑duplex stainless steels such as SAF 2507 and Zeron 100.

Key Features

• Basic coating delivers good welding properties in all positions and high impact strength at low temperatures.
• Provides high strength and excellent corrosion resistance in the weld metal.
• Suitable for service temperatures up to 280 °C (536 °F) and impact testing down to –50 °C.
• Can be used as an overmatching consumable for 21‑23 %Cr duplex stainless steels.
