Hastelloy is an alloy with excellent corrosion resistance, often used in high-temperature, high-pressure environments and under corrosive conditions. Pickling of Hastelloy is performed during the manufacturing process, maintenance, and repair of Hastelloy products and components. Pickling requires specialized knowledge and equipment, and appropriate safety measures must be taken. Additionally, the pickling conditions and treatment time must be set appropriately according to the characteristics of Hastelloy and the usage environment. 【Purpose of the Service】 ■ Removal of oxides and oxide films Oxides and oxide films may form on the surface of Hastelloy due to the manufacturing process or usage environment. Pickling effectively removes these oxides and oxide films, cleaning the surface. This can improve the corrosion resistance and material properties of the alloy. ■ Removal of impurities Impurities may adhere to the surface of Hastelloy during the manufacturing process or handling. Pickling dissolves and removes these impurities using an acidic solution. By removing impurities, the surface quality of Hastelloy and the performance of the products can be enhanced. *For more details, please refer to the PDF document or feel free to contact us.
