Petrochemical Industry Incoloy 925 Strip High Temperature Resistant High

Product Specification

Bright Surface Incoloy 925 Wire Customized Nickel Alloy ASTM B407 Wire with high-performance

Product Introduction

Incoloy 925 strip has a wide range of applications in the petrochemical industry, mainly due to its excellent corrosion resistance and high-temperature strength. The main components of this alloy include nickel (42.0-46.0%), chromium (19.5-22.5%), molybdenum (2.5-3.5%), copper (1.5-3.0%), titanium (1.9-2.4%) and aluminum (0.1-0.5%), and the combination of these components makes it perform well in high temperature and corrosive environments. The physical properties of Incoloy 925 strip include density of 8.08 g/cm³, melting point range between 1311-1366°C, tensile strength of at least 650 MPa, yield strength of at least 295 MPa, and elongation of at least 30%. In the petrochemical industry, Incoloy 925 strip is often used to manufacture pipes, valves, pumps and other equipment, which need to operate stably for a long time in high temperature, high pressure and corrosive working environments. The corrosion resistance of Incoloy 925 enables it to effectively resist the erosion of chlorides, oxidizing acids and other chemicals, ensuring the safety and reliability of equipment. In addition, Incoloy 925 strip has good processing performance and weldability, and can be processed by conventional metal processing processes such as forging, rolling, drawing, etc., which makes it more flexible in manufacturing parts with complex structures.

Parameter

1. Refinery equipment: It can be used in core equipment such as catalytic cracking units and hydrocracking units in refineries to resist corrosion from high temperature, high pressure and corrosive media. For example, it is also used in air heat exchangers in oil refining.
2. Oil and gas extraction equipment: In the field of oil and gas extraction, especially in corrosive environments containing hydrogen sulfide and carbon dioxide, Incoloy 925 strip is widely used in subsea oil well equipment, valves, drill pipe connectors and oil pumps. It can also be used to manufacture oil well casings, oil and gas pipelines and other equipment, which can resist corrosion in high temperature and high pressure environments.

Advantages and Characteristics

1. Excellent corrosion resistance: Incoloy 925 alloy performs well in a variety of corrosive environments, especially in harsh environments such as high temperature and high pressure, chlorine, and sulfide. It has strong resistance to nitric acid corrosion and chloride corrosion, and can effectively prevent pitting and crevice corrosion.
2. Resistance to stress corrosion cracking: Incoloy 925 alloy has excellent resistance to stress corrosion cracking in high temperature and high pressure environments, and is particularly suitable for the oil and gas industry. The nickel content is sufficient to prevent chloride ion stress corrosion cracking.
3. High strength and high toughness: Incoloy 925 alloy obtains higher strength through aging hardening, and its tensile strength can reach more than 965 MPa, yield strength can reach more than 758 MPa, and elongation can reach more than 18%.
4. High temperature performance: Incoloy 925 alloy can still maintain good strength and stability in high temperature environments, and is suitable for high temperature applications. Its creep resistance is particularly outstanding, and it can work stably for a long time under high temperature and high pressure.
