Introduction

1Cr17Ni2 (AISI431) is a martensitic stainless steel which is known for its excellent corrosion resistance and high strength properties (1). The material also has good formability and machinability which means that it can be used for a range of uses. For instance, it can be used in aircraft components, fasteners and turbine components (2). It is also an ideal material for use in medical applications due to its corrosion resistance properties.

Weldability and Formability

1Cr17Ni2 (AISI431) can be welded with either welding processes such as shielded metal arc welding and gas tungsten arc welding. It has good formability which means it can be formed into a variety of shapes (3). It is also easy to work with cold forming and pressing. However, it is not as easy as austenitic stainless steels since its formability is limited by its martensitic structure.

Machinability

1Cr17Ni2 (AISI431) is usually difficult to machine due to its high strength and hardness. It is usually difficult to cut and produce chips without the cracking of the material. The material is also prone to work hardening and surface damage. Therefore, a correct approach must be adopted when machining the material. The best approach is to choose the correct cutting tools with suitable geometries, cutting conditions and speeds (4). The use of annealed state materials and pre-heated materials can also help to reduce wear and tear during machining.

Heat treatment

1Cr17Ni2 (AISI431) can be heat treated to improve its mechanical properties. These treatments can be used to increase the strength, hardness and wear resistance of the material. Annealing is the most common form of heat treatment used in order to relieve any stresses in the material and to reduce work hardening. The material can also be quenched, tempered and aged to increase the strength and wear resistance of the material (5).

Surface treatments

1Cr17Ni2 (AISI431) can also be treated using a variety of surface treatments such as passivation, coating and polishing. Passivating the material helps to improve the corrosion resistance of the material by removing any surface contamination (6). Coating the material can also be used to improve the wear and scratch resistance of the material. Finally, polishing the material can be used to improve its appearance and its surface finish.

Conclusion

1Cr17Ni2 (AISI431) is a chromium-nickel martensitic stainless steel which is used in a range of applications. It has good weldability, formability and machinability which makes it suitable for a range of uses. The material can also be heat treated and treated using surface treatments in order to improve its performance. In conclusion, 1Cr17Ni2 (AISI431) is an ideal material for a range of applications due to its wide range of properties and process performance.
