25mm steel round bar ASTM 350 LF3 bar in fabrication

In high temperature environments, carbon steel LF3 square bars can be used effectively. Most carbon steel LF3 bars are used in the construction of buildings, bridges and ships. Pharmaceutical equipment often uses carbon steel LF3 threaded rods. Carbon steel LF3 round bars are also widely used for heat exchangers and valves. According to CS ASTM A350 gr LF2, forgings should be allowed to cool generally below their conversion range after hot working and before reheating the alloy for heat treatment. In addition to LF787 grades, ASTM A350 LF2 Grade 1 and 2 forgings must be supplied in standardized condition. A350 LF2 butt weld flanges are also available in the normalized and tempered condition or the quenched and tempered condition.
