What is the effect of Mn/Si ratio in steel??

11 November 2016 0 8K Report

Is there a any specific effect of Mn/Si ratio when it's used in welding process??

Our company use erw machine to produce steel pipe, when we used different level of Mn/Si ratio in our production process the result is so fluctuative, sometime we had a good result but sometime we had a bad result.
