Alloy 625 Wire

Alloy 625 Wire - Premium High-Temperature Corrosion-Resistant Wire Solutions

TSM Technology produces Alloy 625 Wire (UNS N06625) with a monthly capacity of 150 tons which exhibits excellent resistance to chloride stress corrosion and oxidation up to 982°C. The wire has a density of 8.44 g/cm³, a tensile strength between 827 MPa (annealed) and 1515 MPa (spring tempered) and meets ASTM B446 and AMS 5837. This non-magnetic wire is used extensively in aerospace, marine and petrochemical applications, reinforced by molybdenum (8-10%) and niobium (3.15-4.15%) in solid solution. 0.1-10.0mm diameters, bright or annealed finishes. 5-20 days delivery.

What is the Alloy 625 Wire?

Alloy 625 Wire is a nickel-chromium-molybdenum superalloy product designed to deliver exceptional performance under high stress and elevated temperatures. Strengthened primarily through solid-solution hardening, this alloy provides excellent resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. It maintains mechanical integrity up to about 1000°C, making it ideal for critical components, welding applications, fastener production, springs, and precision fabrication in aggressive operating environments.

FAQ

Q1: Does product require heat treatment after forming?

A: Generally no. Solid-solution strengthening eliminates this need, though stress-relief annealing at 593–760°C may reduce residual stress in complex shapes.

Q2: What differentiates product from Alloy 718 Wire?

A:Alloy 625 offers superior corrosion resistance with simpler processing. Alloy 718 provides higher strength via precipitation hardening but requires aging treatment.

Q3: Is this wire magnetic?

A:No. Magnetic permeability remains below 1.002, suitable for sensitive electronic and submarine applications.

Q4: Can it weld dissimilar metals?

A:Yes. As ERNiCrMo-3 classification, it's the standard for joining nickel alloys to stainless or carbon steels without cracking.

Q5: What's the maximum operating temperature?

A:It maintains strength up to 982°C, though prolonged exposure above 600°C may cause carbide precipitation affecting impact properties.
