00Cr25Ni4Mo4Ti stainless steel is a ferritic titanium stabilized alloy with a high chromium content. It is an oxidation resistant material suitable for operating temperatures up to 900°C in dry air environments. It is known for its good corrosion resistance and formability and has excellent high temperature strength.
The alloy is composed of 24.3-26.3% chromium, 2.5-3.5% nickel, 4.4-4.8% molybdenum, 0.15-0.35% titanium and the balance iron. The addition of titanium to the alloy helps to create an austenitic-ferritic dual-phase microstructure where the austenite helps to stabilize the high chromium ferrite. This combination gives the material an excellent corrosion resistance when exposed to high temperature oxidation conditions.
The 00Cr25Ni4Mo4Ti material is available in a range of standard forms such as wire, sheets, plates and bars but can also be produced in custom shapes and sizes. It is commonly used to produce components for use in high temperature applications such as exhaust systems, turbine blades, pumps, valves and heat exchangers.
The high temperature strength of 00Cr25Ni4Mo4Ti material is excellent which allows for components to be fabricated and machined to meet customer specific designs. It can be easily welded with no pre-heat treatment required but the weld joints should be stress relieved to improve service life.
The general corrosion resistance of the material is good and it can also resist most stress corrosion cracking and pitting. The advantage of this material is it is able to withstand a range of harsh conditions including water, steam and sea water environments.
It is important to remember, however, that the 00Cr25Ni4Mo4Ti material can be susceptible to corrosion in the presence of chloride and chloric acid. To avoid this it is important to properly clean and protect the surfaces of the parts after fabrication.
Overall, the 00Cr25Ni4Mo4Ti stainless steel is an excellent choice for high temperature applications requiring corrosion resistance, formability and good mechanical properties. It is easily weldable and machinable to create custom components and is resistant to most environmental conditions. With proper maintenance, the 00Cr25Ni4Mo4Ti stainless steel can provide reliable performance in demanding applications.
