1. What is Incoloy 825?

Incoloy 825 is a high-performance nickel-iron-chromium alloy with excellent corrosion resistance to oxidizing acids (such as nitric acid), reducing acids (such as sulfuric acid and phosphoric acid), chloride environments, and sulfide environments. Its mechanical properties remain stable over a temperature range of room temperature to 550°C.

2. Advantages of Freeman Valve's Incoloy 825 API 602 globe valve:

2.1 Freeman Valve's Incoloy 825 API 602 globe valve exhibit excellent corrosion resistance to oxidizing acids (such as nitric acid) and reducing acids (such as sulfuric acid and phosphoric acid), especially performing exceptionally well under medium-concentration sulfuric acid and phosphoric acid conditions at low and medium temperatures;

2.2 Freeman Valve's Incoloy 825 API 602 globe valve possess strong resistance to chloride corrosion, effectively resisting pitting corrosion, crevice corrosion, and stress corrosion cracking (SCC), making them suitable for chlorinated seawater, brine, and chemical media environments;

2.3 Freeman Valve's Incoloy 825 API 602 globe valve is resistant to sulfide corrosion and can be used in acidic oil and gas wells in the oil and gas industry, resisting sulfide stress cracking (SSC);

2.4 Freeman Valve's Incoloy 825 API 602 globe valve maintain stable strength and ductility within a temperature range of room temperature to 550°C, and also possess good toughness at low temperatures, without low-temperature brittleness;

2.5 Freeman Valve's Incoloy 825 API 602 globe valve has excellent weldability;

2.6 Freeman Valve's Incoloy 825 API 602 globe valve effectively prevent intergranular corrosion due to the addition of titanium, which combines with carbon to form carbides, preventing the precipitation of chromium carbides at grain boundaries. This makes them particularly suitable for applications where post-weld solution treatment is not possible.
