EMT pipe bender manufacturer introduces aluminum as deoxidizer commonly used in steel. Adding a small amount of aluminum into steel can refine grain and improve impact toughness, such as 08Al steel for deep drawing sheet. Aluminum also has oxidation resistance and corrosion resistance. The combination of aluminum, chromium and silicon can significantly improve the high temperature non peeling property and high temperature corrosion resistance of steel. The disadvantage of aluminum is that it affects the hot workability, weldability and machinability of steel.
In addition to the familiar elements, there are also many elements that we don't know much about, such as the next three elements. First of all, what EMT pipe bender manufacturers want to say is boron. Adding a small amount of boron into the steel can improve the compactness, hot rolling performance and strength of the steel. Correspondingly, nitrogen can improve the strength, low temperature toughness, weldability and aging sensitivity of the steel.
Finally, EMT pipe bender manufacturers are talking about rare earth elements. Rare earth elements are 15 lanthanides with atomic numbers of 57-71 in the periodic table. These elements are all metals, but their oxides are very similar to earth, so they are traditionally called rare earth. The addition of rare earth can change the composition, morphology, distribution and properties of inclusions in steel, thus improving various properties of steel, such as toughness, weldability and cold workability. The wear resistance of ploughshare steel can be improved by adding rare earth.
