Corrosion High Temperature Resistance Nickel Alloy Incoloy 825 Strip For Petrochemical Industry

Corrosion And High Temperature Resistance 1400°C Nickel Alloy Incoloy 825 Strip For Petrochemical Industry

Product Introduction

Incoloy 825 strip has a wide range of applications in the petrochemical industry, mainly due to its excellent corrosion resistance and high temperature performance. The main components of this alloy include nickel (38%-46%), chromium (19.5%-23.5%), molybdenum (2.5%-3.5%), copper (1.5%-3.5%) and iron (balance), and the combination of these components makes it perform well in high temperature and corrosive environments. The physical properties of Incoloy 825 strip include density 8.14 g/cm³, melting point range between 1370-1400℃, tensile strength of at least 550 MPa, yield strength of at least 220 MPa, and elongation of at least 30%. In the field of petrochemicals, Incoloy 825 strip is often used to manufacture equipment such as pipelines, valves, pumps, etc., which need to operate stably for a long time in high temperature, high pressure and corrosive working environments. The corrosion resistance of Incoloy 825 enables it to effectively resist the erosion of chlorides, oxidizing acids and other chemicals, ensuring the safety and reliability of equipment. In addition, Incoloy 825 strip has good processing performance and weldability, and can be processed by conventional metal processing processes such as forging, rolling, drawing, etc., which gives it greater flexibility in manufacturing parts with complex structures.

Parameter
