1Cr17Ni2Mn15N(AISI205) is an austenitic stainless steel with a medium-low nitrogen content produced by the chromium-nickle-manganese-nitrogen alloying system. This medium-low nitrogen steel is better suited for applications that need to be able to withstand cryogenic temperatures and increased strength. This steel exhibits a higher corrosion resistance due to the fact that it contains higher chromium and nickel content.

The chemical composition of the 1Cr17Ni2Mn15N(AISI205) austenitic stainless steel is C: 0.08%; Mn: 1.2%; Si: 0.7%; Cr: 17.0%; Ni: 2.0%; N: 0.15%; and P: 0.040%. The presence of nitrogen enhances its strength as well as giving it improved corrosion resistance to salt water and crevice corrosive environments. The proportion of this composition gives high strength, formability and toughness in cryogenic temperatures.

Due to the high strength and rigidity at low temperatures, this steel is ideally used in applications like desalination, drilling, and metal processing equipment, as well as cryogenic tanks, valves and cylinders. The stainless steel is also resistant to pitting and scaling in higher chloride concentrations environments and has excellent forming properties.

The corrosion resistance of 1Cr17Ni2Mn15N(AISI205) can be increased with proper annealing and stress-relieving processes. It has a high ductility and good weldability, making it easy to handle. In addition, it is non-magnetic and easy to clean and maintain.

Its best recommended applications include food processing equipment, process equipment, pressure vessels, valves and pumps, cryogenic vessels, piping and tubing, and chemical process equipment. Its strength, low cost and low temperature resistance make it a great option for these industries.

1Cr17Ni2Mn15N(AISI205) is a dependable material and is one of the most desirable products in the stainless steel world. It is multifunctional, cost effective, and easy to fabricate. For this reason, it is becoming increasingly popular with various industries around the world.
