Food Engineering Field Incoloy 800 Strip 690 MPa Forging And Rolling Technology

Product Introduction

Incoloy 800 strip has a wide range of applications in the field of food engineering, mainly due to its excellent corrosion resistance and high temperature performance. The main components of this alloy include nickel (30-35%), chromium (19-23%) and iron (balance), and the combination of these components makes it perform well in high temperature and corrosive environments. The physical properties of Incoloy 800 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 food engineering, Incoloy 800 strip is often used to manufacture equipment such as heaters, steam generators and heat exchangers under high temperature and high pressure conditions. Its corrosion resistance enables it to effectively resist the erosion of chlorides, oxidizing acids and other chemicals, ensuring the safety and reliability of the equipment. In addition, Incoloy 800 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.

Specific Applications

1. Heat exchangers: Heating or cooling operations are often required in food processing, and heat exchangers are key equipment. Incoloy 800 strip has good high-temperature stability and oxidation resistance, and can withstand the high temperature environment during the heat exchange process. At the same time, its corrosion resistance can resist various media commonly used in food processing, such as acidic or alkaline solutions, so it is an ideal choice for manufacturing heat exchanger pipes and plates.
2. Cooking equipment: The food cooking process needs to be carried out under high temperature and humidity conditions, which requires high high temperature resistance and corrosion resistance of equipment materials. Incoloy 800 strip can be used to manufacture cooking pots, cooking tubes and cooking devices, which can effectively resist the corrosion of high-temperature steam and food ingredients.
3. Drying equipment: Food drying equipment needs to remove moisture at high temperatures, and the material needs to have high temperature resistance and oxidation resistance. Incoloy 800 strip is suitable for manufacturing dryers and drying chambers, which can ensure long-term stable operation of the equipment in high temperature environments.
4. Food processing equipment: Food processing equipment such as blenders, crushers and mixers not only need to withstand mechanical stress, but may also come into contact with corrosive foods. The mechanical properties and corrosion resistance of Incoloy 800 strip make it suitable for the manufacture of components for these equipment, which can extend the service life of the equipment and ensure the hygiene and safety of the food processing process.
