Stainless Alloy Steel - Incoloy Stainless Steel

Incoloy Stainless Steel 926 is a super austenitic stainless steel containing 6% molybdenum and improved performance by adding nitrogen. The nickel and chromium it contains make it have good corrosion resistance in a wide range of corrosive environments. This alloy has good corrosion resistance to non oxidizing acids such as sulfuric acid and phosphoric acid. Its high molybdenum content and nitrogen enable it to resist pitting and crevice corrosion, while the copper content enhances its corrosion resistance to sulfuric acid. It can provide excellent corrosion resistance in many highly corrosive aqueous solution environments. One of the most outstanding properties of Incoloy Stainless Steel926 alloy is its excellent corrosion resistance to environments containing chlorides and halides. This alloy is particularly suitable for handling high chloride environments such as saltwater, seawater, corrosive chlorides, and bleaching systems in pulp mills. Its applications include chemical and food engineering, bleaching equipment for pulp and paper, marine and offshore oil platform equipment, evaporators for salt plants, air pollution control systems, as well as condensing pipeline systems, circulating water pipeline systems, and water supply heaters for power plants.

Due to the fact that lncolo 825 N08825 is a corrosion-resistant NI-FE-MO-CU alloy stabilized with Ti, the alloy has effective resistance to uniform corrosion and localized corrosion, and has good performance. Therefore, it has been widely used in chemistry, energy, and wet metallurgy. In addition, the alloy has good toughness and performs well in the atmosphere. However, it should be noted that shallow pitting corrosion may occur in humid environments. This alloy is also resistant to freshwater corrosion and works well in flowing seawater. However, it may develop pitting in still seawater or under polluted conditions. The high nickel content of Incoloy Stainless Steel825 gives the alloy effective resistance to stress corrosion cracking. The corrosion resistance of Incoloy Stainless Steel 825 is excellent in various media, such as sulfuric acid, phosphoric acid, nitric acid, and organic acids, as well as alkali metals such as sodium hydroxide, potassium hydroxide, and hydrochloric acid solutions. The high comprehensive performance of Incoloy Stainless Steel 825 is manifested in nuclear combustion solvers with diverse corrosive media, such as sulfuric acid, nitric acid, and sodium hydroxide, all treated in the same equipment.

Due to the extremely low carbon and silicon content of Incoloy Stainless Steel 59 N06059 nickel based alloy, there is no tendency for impurity phases to precipitate during hot processing and welding, making it suitable for various chemical process industries containing oxidizing and reducing media. The higher content of molybdenum and chromium enables the alloy to resist the erosion of chloride ions

Due to the fact that the lncolo 330 N08830 Alloy 330 is a classic high-performance high-temperature resistant alloy By adding 1.25% silicon element, it has excellent high-temperature strength and still has good resistance to carbonization and oxidation up to 1200 ° C. Meanwhile, Alloy 330 is designed specifically to withstand the thermal shock of quenching. Alloy330 alloy has excellent resistance to chloride ion stress corrosion cracking. When choosing engineering materials, if conventional stainless steel is subjected to stress corrosion (especially at high temperatures), Alloy 330 would be a good choice. The forming and machining of Alloy 330 are similar to austenitic stainless steel and nickel alloy. Under normal circumstances, it is best to perform molding processing at room temperature. In most cases, heat treatment is not required for forming and machining. If necessary, it is recommended to fully anneal at 1038-1121 ° C for rapid air cooling or water cooling. Alloy 330 welding requires the use of the corresponding Alloy 330 welding material. Do not use AWS ER330. Maintain a low interlayer temperature during welding without preheating, using reinforced linear weld beads The machinability index is 20-25% of B1112

Incoloy Stainless Steel 28 N08028 is the stainless steel grade with the highest nickel content. Due to its Ni content exceeding 30%, it is sometimes classified as a corrosion-resistant alloy based on iron shackles. In addition to nickel, this steel has a high Cr content and contains 3% -4% Mo and about 1.0% Cu, making it excellent in overall corrosion resistance in many strongly reducing corrosive environments. In some oxidizing, redox composite, and halogen containing media, it is resistant to both overall and localized corrosion. In addition, this steel also has an austenitic structure, which has excellent strength, plasticity, and toughness. Therefore, this steel is a type of steel with excellent comprehensive performance matching.

The Cr content in Incoloy Stainless Steel 20 N08020 nickel based alloy is usually 19.0-21.0%, and the nickel content is 32.0-38.0%. It is a nickel based alloy containing molybdenum and copper, with excellent hot and cold working properties. Corrosion resistant alloys with many excellent properties have good resistance to oxidative and moderate reducing corrosion, excellent resistance to stress corrosion cracking, and good resistance to localized corrosion. They have satisfactory corrosion resistance characteristics in many chemical process media..
