Short Description:
Incoloy 926 is a super-austenitic with 6%-7% molybdenum stainless steel which exhibits excellent corrosion resistance and resistance against pitting corrosion and crevice corrosion.
Product Description
Incoloy alloy 926 is a super-austenitic stainless steel containing 6% molybdenum and enhanced by an addition of nitrogen. The nickel and chromium contents of this alloy make it resistant to a wide range of corrosive environments. The alloy is especially resistant to non-oxidizing acids such as sulfuric and phosphoric. The high molybdenum content and nitrogen provide resistance to pitting and crevice corrosion, while copper enhances resistance to sulfuric acid. It replaces the conventional, austenitic stainless steels (AISI 316 and 317), where their capabilities are pushed to their performance limits. The alloy, therefore, falls into a “super austenitic stainless steel” category. It can also represent a cost-effective alternative to the higher nickel alloys in some marine and chemical processing environments. One of the outstanding attributes of INCOLOY alloy 926 is its resistance to environments containing chlorides or other halides. This alloy is especially suited to handle high-chloride environments such as brackish water, sea water, caustic chlorides and pulp mill bleach systems.
Incoloy 926 Characteristic
- It has high resistance to pitting and crevice corrosion when in Halide and H2S contained acid media
- In practice, effective in resistance of chloride stress corrosion cracking
- A variety of corrosion have good corrosion resistance capability in the normal oxidation and restore environment
- Upgrade mechanical properties than Cronifer 1925 LC-Alloy 904 L
- Alloys has Improved the stability of metallurgical compared to a range of 18% of the nickel content alloys
- With a certification of applied in manufacturing-related pressure vessel (VdTUV-196 ~ 400C and ASME)
