Mechanical properties of chromium-nickel-manganese-nitrogen austenitic stainless steel 00Cr22Ni13Mn5Mo2N (Nitronic50)

Mochanical Properties of Nitronic50 Steel (00Cr22Ni13Mn5Mo2N)

Introduction

Nitronic 50 is an austenitic stainless steel that is 20% chromium, 7% manganese, 7% nickel, and 2% molybdenum. It was developed to have superior corrosion resistance when compared to conventional austenitic stainless steels. In addition, it has very good resistance to high temperature oxidation and carburizing atmospheres. Nitronic 50 is equally resistant to stress pickling and pitting corrosion. Furthermore, it has a low thermal expansion rate, which is around half of other austenitic stainless steels. Thus, it is widely used in a variety of industries, such as automotive and aerospace, due to its superior mechanical properties. This paper will examine the mechanical properties of Nitronic 50 steel.

Tensile Strength

Tensile strength is a measure of the maximum amount of tensile force that a material can withstand before failing or breaking. It is typically measured in megapascals (MPa). The ultimate tensile strength (UTS) of Nitronic 50 steel is 885 MPa, which is relatively high and exceeds the UTS of many other austenitic stainless steels.

Yield Strength

Yield strength is a measure of the maximum amount of tensile force that a material can withstand before it begins to deform permanently. It is also measured in megapascals (MPa). The yield strength (YS) of Nitronic 50 steel is 677 MPa. This is a relatively high value, indicating the steel has excellent properties.

Elongation

Elongation is a measure of how much a material can elongate prior to fracture. It is usually measured as a percentage. The elongation of Nitronic 50 steel is 15%, which is also very good compared to other austenitic stainless steels.

Hardness

Hardness is a measure of the ability of a material to resist plastic deformation. The hardness of Nitronic 50 steel is 285 HV. This is relatively high and indicates that the steel has excellent properties.

Fatigue Strength

Fatigue strength is a measure of how much a material can withstand cyclic loading before failure. The fatigue strength of Nitronic 50 steel is 550 MPa. This is very high compared to that of other austenitic stainless steels.

Impact Strength

Impact strength is a measure of the amount of energy that a material can absorb before fracturing. It is usually measured in joules (J). The impact strength of Nitronic 50 steel is 98 J. This is significantly higher than that of many other stainless steels.

Conclusion

In conclusion, Nitronic 50 steel has superior mechanical properties when compared to conventional austenitic stainless steels. It has a very high ultimate tensile strength (885 MPa), a high yield strength (677 MPa), a relatively high elongation (15%), a relatively high hardness (285 HV), a very high fatigue strength (550 MPa), and a significantly high impact strength (98 J). These superior mechanical properties make Nitronic 50 steel suitable for a wide range of applications in industries such as automotive and aerospace.
