The advantage of metallic nickel
As the surveys by†metal powder supplier, chromium provide "stainless"corrosion resistance to stainless steel. However, about two-thirds of the current production of stainless steel containing nickel. In the following, we will give some examples of the benefits of containing nickel in stainless steel.
In the choice of materials, the corrosion resistance is only part of the problem. You must make the product easy to make, and may also require additional performance. In stainless steel, nickel and the steel having an austenite structure, it makes the stainless steel easily molded and processed into a complicated shape, the thin and thick sections are easily welded, from a very low temperature to high temperature range can be used, and uneasy to brittle. Stainless steel is also easy to produce, be familiar to the user and widely used. For these reasons, it may be the world's most widely used kinds of steel in the future.
There are other aspects may need to be taken into account. After deforming the ustenitic stainless steelís intensity becomes higher. That means, after the cold working, the materials 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.
Nickel is an excellent material in the corrosion-resistant, also an important alloying element alloy steel. Nickel is an important elements in the formation of austenite steel, low-carbon nickel steel pure austenite the nickel powder content is 24%; while only nickel-containing 27%, the steel in some medium resistance corrosion can be significantly changed. Only the nickel can not constitute the stainless steel. However, the nickel and chromium present in the stainless steel, a nickel-containing stainless steel, but has many valuable properties. Based on the above, we known that nickel as an alloying element in stainless steel, is that it enables the high-chrome steel organization changes, so that the stainless steel corrosion resistance and processing properties can be improved.
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 other types of stainless steel. If the stainless steel containing nickel 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.
Use stainless steel properly 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: improve 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 is that so many stainless steel projects is still in use after so many years.
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 facing the world.
