Product Description

Incoloy 825 is a nickel-iron-chromium alloy engineered for exceptional corrosion resistance in a wide range of demanding environments. The chemical composition of this nickel-based alloy, fortified with molybdenum, copper, and titanium, provides superior performance against reducing acids like sulfuric and phosphoric acid, as well as oxidizing media such as nitric acid.

Unlike many corrosion-resistant alloys that excel only in specific environments, Incoloy 825 offers balanced resistance to both reducing and oxidizing acids. The addition of molybdenum and copper provides outstanding protection against pitting and crevice corrosion, while titanium stabilization ensures immunity to intergranular attack. With a minimum nickel content of 38%, Alloy 825 also offers proven resistance to chloride-induced stress-corrosion cracking.

This combination of properties makes a premier material for critical applications across chemical processing, pollution control, offshore oil and gas, and marine engineering. Common trade names include Incoloy 825, Alloy 825, Nickelvac 825, and Nicrofer 4241.

Key advantages:

  • Broad Corrosion Resistance: Excellent resistance to both reducing and oxidizing acids
  • Stress-Corrosion Cracking Resistance: High nickel content (38-46%) provides proven SCC resistance
  • Pitting & Crevice Corrosion Resistance: Molybdenum and copper additions enhance localized corrosion protection
  • Intergranular Attack Immunity: Titanium stabilization prevents weld decay and sensitization
  • Versatile Fabricability: Excellent weldability and formability using standard techniques
  • NACE MR0175 Approved: Certified for oil and gas service in sour environments

    Precision cold rolled stainless steel strip is a narrow, thin-gauge stainless steel product manufactured to significantly tighter thickness and width tolerances than standard cold-rolled sheet. Unlike standard sheet (typically 1000mm or 1219mm wide), precision strip is produced in narrow widths — usually less than 600mm — and thin gauges from 0.05mm up to 3.0mm. The key differentiator is the tolerance : the precision strip holds thickness variations to as low as ±0.005mm,
