The advantages of nickel in stainless steel
As we all known, nickel is one of the integral ingredients of stainless steel. It is because of the nickel, stainless steel has a stainless steel capacity, here I will analysis the role and the advantages of nickel in stainless steel: chromium provide the stainless steel "stainless" of the basic corrosion resistance.
However, about two-thirds of the current production of stainless steel containing nickel. In the following, we give some examples of the benefits of containing nickel stainless steel.
In the choice of material, the corrosion resistance is only part of the problem. You must make the product easy to make, and may also require additional performance. As the surveys by metal powder supplier, nickel make the steel with austenitic microstructure, it makes the stainless steel easily molded and processed into a complicated shape, thin, thick sections are easily welded, from a very low temperature to high temperature range can be used, but not brittle. 18/8 stainless steel is also easy to produce, are familiar to the user, are widely used. For these reasons, it may be the world's most widely used steel. There are some other aspects may need to be taken into account. Austenitic stainless steel after deformation intensity becomes higher. This means that, after the cold working of the material can be used to manufacture lighter structure. When it is deformed to absorb a large amount of energy, this may be useful in the design of the structure of a vehicle, to provide protection in the event of a collision. Appearance is equally important. Looking around any modern city, the appearance of the nickel-containing austenitic stainless steel make it popular in various surface processing of building applications as well as interior decoration.
There are some other types of stainless steel. If the stainless steel containing nickel power is low or very low, and does not contain other stable austenite elements such as manganese or nitrogen, as stainless steel has a ferritic structure. Moderate nickel content mixture of austenite and ferrite tissue, or said duplex structure. In the decision of the microstructure and properties of most steels, nickel plays an important role. The proper use of stainless steel to ensure corrosion resistance, stainless steel project will be in service for many years. This durability means that play a significant role in the development of a more sustainable society: energy efficiency, reduce pollution, reduce the use of materials. In addition, all of alloying elements (not only the value of a nickel), provides a powerful incentive, at the end of the life of stainless steel products, recovery of these substances, and re-used in the production of stainless steel. In fact, stainless steel is a material recycling rate of all materials. The only factors that limit the stainless steel recycling amount is so many stainless steel projects through many years is still in use.
Nickel has played a crucial role in the provision of comprehensive performance, and the stainless steel become the fastest-growing kind of material, is an important solution for the sustainability challenges that the world facing.
