304 stainless steel flat bar
Introduction
Name: 304 stainless steel flat bar
From the perspective of metallography, because the stainless steel containing chromium and the surface of the formation of a very thin chromium film, the membrane separated from steel intrusion of oxygen from the corrosion-resistant role.
Stainless steel flat steel is one of the steel, 304 stainless steel flat bar is generally divided into hot-rolled flat steel and cold drawn flat steel. Hot rolled 304 stainless steel flat surface of the general delivery status for pickling, cold-drawn 304 stainless steel flat surface of the general delivery status for the drawing polishing.
