Parameter | Incoloy 825 Strip | Other Nickel Alloys | Stainless Steel |
|---|---|---|---|
Acid Corrosion Resistance | Outstanding against sulfuric, phosphoric, nitric | Good, but less consistent across acids | Poor, corrodes quickly in strong acids |
Temperature Resilience | Excellent at high temperatures | Varies, some weaken at extreme heat | Limited, degrades under high temps |
Fabrication Ease | Easy to form, weld, and cut | Moderate, some alloys harder to work with | Easy, but corrosion limits applications |
Pitting/Crevice Corrosion | Superior resistance in chlorides | Moderate, depends on alloy | Poor, highly prone to pitting |
Oxidizing Media Resistance | Strong in oxidizing and reducing conditions | Varies, some struggle with oxidizing media | Better in oxidizing, weak in reducing acids |
Durability | Extremely durable, long service life | Moderate to high, depends on alloy | Moderate, shorter lifespan in harsh settings |
Chemical Versatility | Handles wide range of corrosives | Good, but less versatile | Limited, fails in aggressive chemicals |
Cost-Effectiveness | Higher upfront cost, long-term savings | Varies, some cheaper but less durable | Low cost, but frequent replacements needed |
