Heat Treatment Elongation 30% Incoloy Alloy 800H Strip In Chemical Industry

Product Introduction

Incoloy Alloy 800H strip is widely used in the chemical industry, 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), as well as small amounts of aluminum (0.15-0.60%) and titanium (0.15-0.60%). The combination of these components allows Incoloy 800H to maintain good mechanical properties and chemical stability at high temperatures. Its physical properties include a density of 8.0 g/cm³ and a melting point range of 1350-1400℃. In the chemical industry, Incoloy 800H strip is often used to manufacture equipment such as reactors, heat exchangers, evaporators, etc., which often need to withstand high temperatures and corrosive media. The corrosion resistance of Incoloy 800H is especially good in high temperature environments. It has excellent tolerance to corrosive media such as oxidation, sulfidation, and chlorination. In addition, Incoloy 800H strip has good processing properties and can be processed by conventional metal processing processes such as forging, rolling, drawing, etc. These characteristics make Incoloy 800H strip an indispensable material in the chemical industry, ensuring the long-term stable operation of equipment in high temperature, high pressure and corrosive environments.

Parameter

1. High temperature reactor: Incoloy 800H strip is used to manufacture high temperature reactors, which can operate for a long time in harsh environments such as high temperature, high pressure, and strong corrosion. Its excellent oxidation resistance and corrosion resistance make it an ideal choice.
2. Acidic medium reactor: In reactors that handle acidic media such as sulfuric acid, hydrochloric acid, and hydrofluoric acid, Incoloy 800H strip can effectively resist corrosion and extend the life of the equipment.
3. High temperature heat exchanger: Incoloy 800H strip is used to manufacture high temperature heat exchangers, which can maintain stable performance under high temperature and high pressure conditions and effectively resist corrosion and oxidation.
4. Chemical heat exchanger: In chemical production, heat exchangers need to withstand the dual test of high temperature and corrosive media. Heat exchanger tube bundles made of Incoloy 800H strip can effectively improve heat exchange efficiency and extend the service life of equipment.
5. High temperature distillation tower: Incoloy 800H strip is used to manufacture high temperature distillation towers, which can operate stably for a long time under high temperature and high pressure environments and effectively resist corrosion.
