Weld Star Alloy 82 NiCr-3 Wire [15kg Spool]

The Weld Star Alloy 82 (NiCr-3) is a high performance nickel chromium solid MIG wire designed for the most demanding industrial environments. Often referred to as the "Swiss Army Knife" of high alloy welding, Alloy 82 is widely used for joining nickel alloys like Inconel 600, 601, and 800, as well as for complex dissimilar metal joints between stainless steels, carbon steels, and low alloy steels.

The weld metal provides exceptional mechanical properties, including high tensile strength and superior resistance to oxidation and "creep rupture" at elevated service temperatures. Its versatile chemistry also makes it highly reliable for cryogenic applications, maintaining toughness where other alloys would fail. Precision layer wound on 15kg BS300 spools, this wire is a staple in the power generation, petrochemical, and nuclear industries for both structural welding and high quality corrosion resistant overlays.

Key Features

Exceptional Dissimilar Joining: The premier choice for transition welds between stainless steel and carbon steel, or different nickel based alloys.

Thermal Range Versatility: Performs flawlessly in service environments ranging from liquid gas temperatures (cryogenic) to high heat furnace applications.

Superior Corrosion Resistance: High Chromium and Nickel content provides excellent protection against oxidation and chemical attack.

High Creep Rupture Strength: Engineered to maintain structural integrity under constant stress at high temperatures.

Precision Feed ability: Layer wound to ensure consistent wire delivery, crucial for the expensive and sensitive nature of nickel alloy fabrication.

Overlay & Cladding: Ideal for surfacing carbon steels to create a corrosion resistant barrier in aggressive media.
