Pipes made of stainless steel grade X2CrNiMoN19-11-2 are used for applications that require high corrosion and temperature resistance. This stainless steel material offers a wide range of properties including excellent strength, formability and weldability.
X2CrNiMoN19-11-2 stainless steel grade is classified as a superaustenitic stainless steel which is well-suited for several applications like chemical and petrochemical process equipment, chemical transportation, reactions and heat exchangers, stainless steel kitchen equipment and equipment used in food processing. The chemical composition of X2CrNiMoN19-11-2 helps make this stainless steel grade highly corrosion-resistant and able to withstand higher temperatures than traditional steels while retaining its good strength properties. This stainless steel grade is characterized by its high molybdenum and nitrogen content, which gives it superior pitting and crevice corrosion resistance.
X2CrNiMoN19-11-2 stainless steel grade is also used in pharmaceutical equipment and chemical applications due to its excellent corrosion resistance and formability. Furthermore, due to its high chromium content and addition of nickel, this stainless steel grade offers good resistance to stress corrosion cracking in certain concentrations of chloride-containing media. The low carbon content of X2CrNiMoN19-11-2 stainless steel ensures that there are no problems with weld hot cracking. This stainless steel is also non-magnetic due to its austenitic structure, making it suitable for certain applications such as pharmaceutical and food processing equipment where contact with magnets is not desirable.
Welding X2CrNiMoN19-11-2 stainless steel requires the use of special techniques and care, as these types of stainless steel grades are especially sensitive to heat distortion and cracking. It is recommended to use filler materials with a matching composition to the parent material, as well as preheating and post-weld heat treatment processes.
The successful use of X2CrNiMoN19-11-2 stainless steel requires that an experienced welding and fabrication team is used. Pipes made out of this stainless steel grade offer exceptional corrosion resistance and temperature resistance properties and are used in a wide range of demanding applications. The high level of performance and reliability makes X2CrNiMoN19-11-2 stainless steel grade pipes an optimal choice for many industries requiring pipes with severe corrosion and temperature resistance properties.
