Exaton Ni72HP (SAW)

Exaton Ni72HP is a high‑performance filler material for Submerged Arc Welding (SAW) of nickel‑based alloys, high‑temperature stainless steels, and Ni‑Cu alloys. It is designed for demanding environments, offering excellent corrosion resistance and high temperature capability.

Key Features

• Suitable for joining NiCrFe alloys, 9% Ni steels, stainless‑to‑carbon steels, and NiCu alloys.
• Operates in air up to 1175 °C (2145 °F) and in sulphur‑dioxide atmospheres up to 800 °C (1470 °F).
• Consistent wire quality with tight chemistry and dimensional tolerances.
• Innovative corrosion‑resistant chemistry with high Cr and Mo content.
• Delivered in moisture‑resistant steel drums (20–25 kg) with low‑moisture flux.
