Angle steel is a kind of profile with L-shaped corner.
L stands for continuous casting, that is, direct steelmaking without waiting for cooling after ironmaking.
L907A is mainly used for shipbuilding, and can be made into spherical flat steel and angle steel. High temperature heat treatment, tempering and tempering can be carried out according to the needs of use. Rolling processes such as cold rolling and hot rolling can also be adopted.
Although L907A steel is a military material in our country, it is still far from the world advanced standards, and it needs to continue to work hard.
