2.Alloy 4618: The corrosion-resistant choice.
2.As a deformed and corrosion-resistant alloy, 4618 alloy stands out for its excellent sulfur and phosphoric acid resistance, making it an ideal choice in various corrosive environments. Thanks to its clever composition, the alloy exhibits excellent corrosion resistance in seawater, industrial water, and redox media. Here's an in-depth breakdown of 2The composition, performance characteristics and key role of alloy 4618 in a wide range of applications.
Superior Composition:
2.Alloy 4618 achieves an ideal balance of excellent performance in different media by reasonably regulating the content of carbon, silicon, manganese, phosphorus, sulfur, nickel, chromium, molybdenum, iron, tungsten, copper, cobalt, NB+TA and other elements. Of particular note is the fact that by reducing or removing the composition of carbon, silicon, iron and vanadium, the alloy is able to improve its thermal stability and become a leading corrosion-resistant alloy.
Superior corrosion resistance:
2.Alloy 4618 has excellent performance in sulfuric acid, phosphoric acid and other media, and also has excellent corrosion resistance to mixed media containing fluorosilicic acid, sulfate, chloride ions, fluoride ions, and nitrate sulfuric acid. Its outstanding resistance to intergranular corrosion, pitting and crevice corrosion makes it an ideal material for handling all kinds of corrosive media.
Ease of processing and welding:
2.Alloy 4618 has excellent deformability when hot working and is suitable for temperatures in the range of 900 1150 degrees. After thermoforming, solution treatment is recommended to maintain its superior corrosion resistance. The cold working performance is also excellent, but there is a certain tendency to work harden compared to stainless steel, so careful consideration is required when selecting molding equipment. In addition, the alloy performs well in welding, is suitable for a variety of welding processes, and does not require heat treatment after welding, providing great convenience to the manufacturing process.
Ideal physical properties:
2.The physical properties of Alloy 4618 include moderate density, high melting point, and good specific heat capacity and thermal conductivity, which enable it to maintain excellent performance at high temperatures, providing reliable support for engineering design.
Wide range of applications:
Due to its excellent corrosion resistance in various media, 2Alloy 4618 is widely used in various industrial sectors. Especially in the fields of sulfuric acid, phosphoric acid, wet phosphoric acid, pollution control and the paper industry, the alloy has become the material of choice for the manufacture of pipes, pipe fittings, vessels, heat exchangers, pumps, valves and other equipment.
Summary: Overall, 2Alloy 4618 is ideal for use in a wide range of corrosive environments due to its excellent corrosion resistance and versatility. The alloy offers unrivalled advantages in the process of handling highly corrosive media, providing a reliable solution for engineering design.
