Mechanical Properties of Cr-Ni-Mn-N Austenitic Stainless Steel AISI201
Cr-Ni-Mn-N austenitic stainless steel AISI201 (1Cr17Ni5Mn6N) is a low carbon stainless steel. It has good ductility, toughness and resistance to stress corrosion cracking. It is suitable for applications in harsh chemical, such as soaps and chemical agents, as well as in food processing. This grade has a wide range of uses in construction, automotive, chemical and other industrial applications.
The mechanical properties of this stainless steel grade AISI201 include a combined yield strength of 350 MPa, an ultimate tensile strength of 590 MPa, and an elongation of 40%. The hardness of AISI201 is also quite high, with a Brinell hardness of 210-250. As a low carbon stainless steel, it is also not prone to hardening during welding and other forming processes, making it a good choice for welding and other forming operations.
Due to its low content of nickel and manganese, AISI201 has higher corrosion resistance than that of other high carbon steels. This stainless steel grade is a good choice for environments where chlorine or other strong oxidizing agents are present. It has a higher resistance to sulfuric acid than other stainless steel grades, and is capable of resisting temperatures up to 650°C without suffering any damage.
Ultrasonic and X-ray testing are useful tests for determining the properties of AISI201 stainless steel. X-ray tests help identify voids, shrinkage, and other structural defects in the material. Ultrasound is also useful for determining structural properties that X-ray cannot, such as porosity, wall thickness, and surface integrity.
The strength of 1Cr17Ni5Mn6N is dependent on the tempering and quenching treatments applied after the manufacturing process. Quenching is the process where the steel is heated to a high temperature followed by a cooling cycle. This treatment causes the steel to become harder, but can also cause internal stresses which can reduce the material’s strength. Tempering is the process where the material is heated to a particular temperature and then cooled quickly, which can reduce hardness but can also reduce internal stresses and increase the strength and ductility of the material.
Overall, AISI201 is a reliable and cost-effective choice for many industrial applications. It has good formability and weldability, good strength and hardness properties, and good corrosion resistance. It can resist temperatures up to 650°C and has an overall good performance. While it may not have the best properties in comparison to other stainless steel grades, AISI201 is an excellent choice where cost-effectiveness is an important factor.
