Technological properties of chromium-nickel-manganese-nitrogen austenitic stainless steel 1Cr17Ni5Mn6N (AISI201)

Process Performance of AISI 201 (1Cr17Ni5Mn6N) Stainless Steel

Introduction

AISI 201 (1Cr17Ni5Mn6N) Stainless Steel is a ferritic chromium-nickel-manganese-nitrogen austenitic stainless steel. AISI 201 stainless steel has excellent formability and weldability, which makes it very suitable for the majority of both industrial and consumer products. It has good corrosion resistance and excellent heat treatability to a range of temperatures. This article discusses the process performance of AISI 201 stainless steel.

Formability

AISI 201 stainless steel has good formability, with a minimum percentage elongation of 16%. AISI 201 can be easily formed into any shape with the appropriate tooling and equipment. It can also be used in a wide variety of forming processes, including stretching, drawing, stamping, rolling, and spinning. AISI 201 also has excellent spring properties, making it well suited for anything from watch springs to musical instruments.

Weldability

AISI 201 stainless steel has excellent weldability, which makes it very useful for a variety of applications. Its relatively low chromium content makes welding easier than higher-chromium grades. AISI 201 is suitable for both cold and hot welding. AISI 201 relies on the filler materials to provide strength at the joints; therefore, careful selection of filler material is important to ensure good welds.

Heat Treatability

AISI 201 stainless steel can be heat treated to a range of temperatures. It is recommended that the anneal temperature should be between 1050°C and 1150°C. Heat treating AISI 201 can improve its strength, hardness, and resistance to corrosion.

Machinability

AISI 201 stainless steel has good machinability, with a machining rating of 50. This means that AISI 201 can be machined quickly and relatively easily compared to other grades of stainless steel. However, dry cutting is recommended to avoid discoloring and achieving a better finish. If a lubricant is used during machining, it is important to use a lubricant with a low sulfur content.

Corrosion Resistance

AISI 201 stainless steel has a good corrosion resistance due to its 11% chromium content. However, it is also susceptible to inter-granular corrosion, which is caused by the formation of chromium-rich carbides at high temperatures. Care must be taken to ensure that the temperature is not too high during heat treatment, otherwise inter-granular corrosion may occur.

Conclusion

AISI 201 (1Cr17Ni5Mn6N) stainless steel is a ferritic chromium-nickel-manganese-nitrogen austenitic stainless steel. It has excellent formability, weldability, and heat treatability, and it can be easily machined. AISI 201 also has good corrosion resistance, although care must be taken to ensure that the temperature is not too high during heat treatment to avoid inter-granular corrosion.
