High chromium ferritic stainless steel 00Cr25Ni4Mo4Ti (UNSS44635) Typical use

Introduction of 00Cr25Ni4Mo4Ti

00Cr25Ni4Mo4Ti (UNSS44635) is a type of ferritic stainless steel, which contains 25% chromium, 4% nickel, 4% molybdenum, and 0.82% titanium. It is known for its high tensile strength and ability to maintain an excellent level of corrosion resistance even after being exposed to extreme temperatures and pressures. It also has a low coefficient of thermal expansion and good thermal shock resistance. It can be found in many industrial applications, such as automotive and aircraft components, oil and gas exploration, pump and valve components, and a variety of chemical processing equipment.

Performance & Features

00Cr25Ni4Mo4Ti offers a unique combination of features which make it well-suited for a variety of applications. It has excellent corrosion resistance due to its high chromium content, and it is resistant to both stresses and fractures. Additionally, it has an increased strength-to-weight ratio and is highly resistant to oxidation and heat. It has good thermal shock resistance and is suitable for high pressure and temperature applications, such as in oil and gas production. Another feature of 00Cr25Ni4Mo4ti is its low coefficient of thermal expansion, which makes it more thermally stable than other stainless steels.

Welding

00Cr25Ni4Mo4Ti can be welded using either metal inert-gas (MIG) welding or shielded metal arc welding (SMAW) processes. Because of its high chromium content, the recommended filler metal for welding is 309L or 310L. Pre-heating and post-weld heat treatment should both be used to reduce the risk of cracking.

Applications

00Cr25Ni4Mo4Ti is a versatile material and is used in many industries, including automotive, aircraft, oil and gas, chemical processing, and pumps and valves. It is used to make components in automotive and aircraft applications due to its self-passivation and resistance to heat and chemicals. It is also used to make piping and valves in oil and gas production due to its excellent corrosion resistance and high tensile strength. Additionally, it is used as a material for tanks, vessels, and pumps in chemical processing due to its good thermal shock resistance.

Conclusion

00Cr25Ni4Mo4Ti is an excellent material for a variety of industrial applications. It has excellent corrosion resistance and strength, and its low coefficient of thermal expansion makes it thermally stable. Additionally, it has good thermal shock resistance, making it suitable for high temperature and pressure applications. Due to its unique combination of features, it can be found in many industrial applications, such as automotive, aircraft, oil and gas, and chemical processing.
