The Role Of Trace Elements In Stainless Steel 304 Wire Oct 23, 2017

The trace elements in the Stainless Steel 304 Wire are critical, for example, that chromium plays a decisive role in the Stainless Steel 304 Wire, and each Stainless Steel 304 Wire must contain a certain amount of chromium. Until now, there is no chromium-free Stainless Steel 304 Wire. Chromium is the main element in determining the performance of stainless steel. The reason is that the addition of more than 12% chromium to the steel as an alloying element, the steel surface automatically forms a very thin, colorless, transparent and very smooth layer of chromium oxide Film (that is, passivation film), the formation of this layer greatly reduced the oxidation of steel.

Nickel and chromium in the Stainless Steel 304 Wire plays an important role in the role of nickel in stainless steel is that it changed the crystal structure of steel, stainless steel in the increase in nickel is a major reason for the formation of austenite crystal structure, thereby improving and strengthening the chromium Of the passivation mechanism, its resistance to intergranular corrosion is improved, while processing, weldability and toughness and other mechanical properties.

Stainless Steel 304 Wire (or stainless steel products), is limited rare alloy elements added to the steel base, the formation of different characteristics of a special purpose products. Improve the recycling of stainless steel products, with the sustainable development of the far-reaching significance of the economy.

Conventional Stainless Steel 304 Wire products mainly include two categories: disc and straight. Often the Stainless Steel 304 Wire (or stainless steel product) is determined by the chemical composition of the steel. The primary reason for chromium to improve the corrosion resistance of steel is that chromium increases the electrode potential of the iron-chromium alloy. When the atomic fraction of chromium in the iron-chromium solid solution reaches 12.5% (n / 8, atomic ratio), the electrode potential in the FeSO4 solution is increased from -0.56V to + 0.2V, % Of the atomic fraction as the minimum chromium content of stainless steel, called stainless steel.

This can only be said that there is relative corrosion resistance in dry air, but different media, there should be other elements of the increase, which developed, included in the standard steel to 143 (not including the steel According to the special requirements of the development of enterprises within the standard steel, high temperature alloys, corrosion alloys, precision alloys and other steel). However, with the changing climate of the world, the continuous reduction of resources, the improvement of people's quality of life, given the new concept of Stainless Steel 304 Wire (or stainless steel) - clean Stainless Steel 304 Wire products. According to the definition of clean technology, refers to the comprehensive prevention of environmental protection strategies continue to be used in the production process and products, with a view to reducing the risk of human and the environment, that is, before the pollution to take countermeasures to eliminate pollutants in the production process, The implementation of industrial production throughout the process control.
