2 3/4 inch plate A573gr.70 carbon-manganese-silicon steel plate mill

On 18th December, 2019, BBN Group decorated the office A573gr.70 carbon-manganese-silicon steel plate building with many kinds of pendant. There were christmas trees, gifts and snowflakes in the logo wall. At the same time, we made a video at the Zhengzhou office to celebrate the coming Christmas holiday. Our A573gr.70 carbon-manganese-silicon steel plate oversea sales team and market delevopment team wish you Merry Christmas and Happy New Year. Besides, we prepare some meaningful gifts for our old customers.

The purpose of complete annealing of A573gr.70 carbon-manganese-silicon steel plate, wear-resistant plate is to improve the bad structure, such as coarse grain, widmanstatten structure (coarse ferrite with directional growth along with coarse grain) or banded structure caused by high temperature during hot forging, hot rolling, welding or casting of steel plate, so as to refine grain, improve mechanical properties, and reduce stress and hardness.
