Effect of chemical elements on steel - Tubecon
The influence of chemical elements on the properties of steel are not only dependent on the type of element added to the steel but also the amount of the alloying element that is added. For example, Si can cause low galvanizing thickness at both low concentration or high concentration but in a mid-region will cause the zinc layer to be thick.
