grams per cubic centimeter) and a high melting point (approximately
1,345°C) while having a low coefficient of linear expansion (12.8 x
10^-6/°C).
In the chemical processing industry, Inconel 625 rods are widely
used in various key equipment and components, especially those
working in corrosive gases, liquids and high-temperature media. It
is used to manufacture reactors, heat exchangers, distillation
columns, storage tanks and piping systems, etc. Due to its
excellent corrosion resistance, Inconel 625 rods are able to
withstand a variety of corrosive media, including acids, alkalis,
salts and oxides, etc., maintaining equipment reliability and long
life.
In addition, Inconel 625 rods are also commonly used in the
manufacture of catalyst system components such as catalyst
supports, catalyst baskets, catalyst tubes and catalyst reactors.
It has excellent high-temperature strength and corrosion
resistance, and can withstand high temperatures and corrosive
environments during the catalyst reaction process.
Inconel 625 rod has excellent mechanical properties, including high
yield strength (approximately 590 MPa) and tensile strength
(approximately 760 MPa), allowing it to withstand the high loads
and stresses found in the chemical processing industry.
Overall, Inconel 625 rod plays an important role in the chemical
processing industry due to its excellent corrosion resistance, high
temperature strength and mechanical properties. It is widely used
in key equipment and components such as reactors, heat exchangers,
storage tanks, piping systems and catalyst systems to ensure the
safety and efficiency of chemical processing processes. The wide
application range and excellent performance of Inconel 625 rod make
it one of the indispensable materials in the chemical processing
industry.
