Reasonable cutting procedure of A387 gr 11 pressure vessel steel sheet

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This A387 gr 11 pressure vessel steel sheet rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

Main uses of A387 gr 11 pressure vessel steel sheet, special steel. First, special steel is used for bearing manufacturing. Second, the special steel is used for mold manufacturing, which can withstand high temperature very well, and has excellent repeated use performance, which makes the mold quality excellent also. Third, the special steel is used in the manufacture of spring plates, and the chassis of some cars need to use the spring plate, which has good elasticity and flexibility. Fourth, the special steel is used in the aerospace industry. Fifth, the special steel is used to manufacture hardware products such as knives and drill bits.
