Inconel600 Material introduction

Inconel600 Nickel chromium iron alloy（UNS NO6600/W.Nr.2.4816）is a standard engineering material for corrosion and heat resistant applications. At the same time, the alloy has excellent mechanical properties, high strength and good processability. The high nickel content makes the alloy resistant to many organic and inorganic compounds, and at the same time, the alloy is fundamentally immune to chloride stress corrosion cracking. Chromium is resistant to sulfide and high-temperature oxidation conditions or corrosive solutions. This alloy cannot be precipitation strengthened, and its hardening or strengthening can only be achieved by cold work.

The versatility of Inconel 600 allows it to be used in a wide range of temperatures ranging from low temperatures to 2000 ° F (1095 ° C). Due to its high strength and corrosion resistance, the alloy has been widely used in chemical industry, including heaters, distillers, bubble cap towers and condensers in fatty acid process; Evaporator tube, tube sheet and tablet plate in sodium sulfide manufacturing process; Rosin acid treatment equipment in pulp manufacturing.

The high temperature strength and oxidation resistance of alloys make them used in many heat treatment industries. It is used for kettle, muffle, rolling furnace wall and other furnace parts, as well as heat treatment blue and tray. In the aviation field, Inconel 600 is used in various engines and airframe components that withstand high temperatures. For example: lock wire, exhaust lining and turbine seal.

is used in electronic industry, such as cathode ray tube support, thyratron grid, tube support diaphragm and spring. This alloy is a standard material for nuclear reactor construction. It has excellent corrosion resistance to high-purity water, and there is no sign of chloride stress corrosion cracking in the reactor water system. In nuclear applications, this alloy is produced according to strict specifications and is designated Inconel 600T alloy.
