The X12CrNi22-12 alloy is a stabilized austenitic stainless steel formulated by DIN for special applications. It contains about 18% chromium, 8.5% nickel, and 2% titanium.
It is mainly used in applications where oxidation resistance is important, such as alkaline and oxidizing environments, as well as elevated temperature environments. Its superior oxidation resistance is attributed to titanium stabilizing the steel. It is also considered a suitable choice for weldable solutions in most cases.
X12CrNi22-12 is therefore suitable for use in a variety of different verticals, including power generation and petrochemical engineering, as well as food handling and steam processing. It is regularly used in piping systems, pressure vessels, tanks, and other general-purpose applications requiring oxidation resistance.
Power generation and petrochemical engineering typically benefit the most from X12CrNi22-12’s superior oxidation resistance, allowing them to last for longer amounts of time, even in corrosive environments. Its high chromium and nickel contents also make it a popular choice for heat exchangers and header tanks.
The food handling and steam processing vertical also makes use of X12CrNi22-12. Its superior oxidation resistance allows it to resist corrosion even in long-term exposure to high temperatures. In addition, its titanium stabilizing element allows it to resist oxidation, which makes it an ideal choice for food manufacturing and packaging equipment, steam pipe systems, and steam vessels.
Finally, X12CrNi22-12 is regularly used in general-purpose applications due to its superior oxidation resistance and weldability. Piping systems, pressure vessels, tanks and other equipment composed of the alloy can withstand corrosive environments, high temperatures, and prolonged periods of stress without risk of failure.
Clearly, X12CrNi22-12 serves an important role in numerous verticals across various industries. Its superior oxidation resistance and weldability has made it a frontrunner in numerous applications, making it an essential part of many engineering designs.
