QuNi25 Rod – Laser Welding Wire Alloy 825 / 2.4858 (NiFeCr, ERNiFeCr-1)

QuNi25 is a nickel-base wire for highly corrosion-resistant steels: DIN EN ISO 17274 S Ni 8065 · AWS A5.14 ERNiFeCr-1 · material no. ~2.4858 (Alloy 825).

The weld metal is fully austenitic and therefore highly resistant to stress corrosion cracking and pitting in chloride-bearing media — the two failure modes that defeat ordinary stainless steels in chemical plants. It is designed for exposure to sulphuric and phosphoric acid and is corrosion-resistant in sea water. Besides matching joints it suits dissimilar welds.
