What is Nickel Alloy 31?
Alloy 31 (N08031) nickel-based alloy is a nitrogen-containing iron-nickel-chromium-molybdenum alloy with properties intermediate between super austenitic stainless steels and established nickel-based alloys.Alloy 31 (N08031) nickel-based alloy is suitable for applications in the chemical and petrochemical industries, in environmental engineering, and in the production of oil and gas.
Characteristics:
Excellent corrosion resistance in halogenated media, whether acidic or alkaline.
Excellent corrosion resistance in sulfuric acid at any concentration.
Excellent corrosion and erosion resistance in phosphoric acid media .
Excellent resistance to localized and uniform corrosion in chlorine dioxide bleach media.
Excellent corrosion resistance in both reducing and oxidizing environments.
Easy to process and weld.
Has the certification that can be used to manufacture pressure vessels with a wall temperature of -196～450℃.
Alloy 31 high temperature alloy has a wide range of applications. It is commonly used in the production of various types of electromechanical equipment with high-performance requirements, storage tanks for strong acids and alkalis, automotive exhaust gas processors, treatment of concentrated sulfuric acid and other equipment in the industrial field, as well as related devices in the field of aviation and medicine.
The Surface Treatment of Shot Peening:
Surface shot peening of pipes is a surface treatment method in which powerful metal particles or abrasives are blasted at high speeds onto the surface of metal pipes through the use of shot peening equipment. This process removes oxidation, rust, oil and other impurities from the surface, thereby improving the quality and cleanliness of the metal surface.
The principle of the blasting process is to utilize the impact and friction of the abrasive material to effectively clean the metal surface, making it more uniform and smooth and improving the surface roughness of the metal. This not only helps to improve the surface quality of the metal, but also provides a better basis for subsequent painting, plating or other surface treatments.
Surface blasting is widely used in the manufacturing industry, especially in the preparation of metal pipes, steel structures and other metal products. This process helps to improve the corrosion resistance and extend the service life of metal products and also provides a better basis for adhesion to subsequent processes.
