When the conventional shape and size steel can not meet the actual demand, there are many special-shaped steels. There are many different kinds of special-shaped steel based on cold drawn special-shaped steel. Some of them are divided according to different materials, and some are differentiated according to different uses.
1. Classification of cold drawn special-shaped steel in mine
It can be divided into the steel plate used in mining machinery, which is used in 45# steel as the material produced; a ratchet type steel is used for rock drilling machine parts, its use of the material is 20Cr steel and steel belt type; mining machinery parts used, 35CrMo steel is the main raw material it.
2. Different types of cold drawn special-shaped steel for automobile
Known as a supporting teeth steel, specially for automobile wrench ratchet handle supporting teeth; the other is a semi-circular steel in automobile and turbine manufacturing field with more, the selective material is widely used, 45#, 45B, 1Cr13 steel can.
There is also a pin - shaft type steel used for automobile pin shaft, which is often made of 45# steel as the main material. In addition to this, there are also cam - shaped steel. It is a steel product for the manufacture of automobile shaft and automotive engine parts.
3. Types of cold drawn special-shaped steel for light textile mechanical and electrical use
More varieties of cold drawn shaped steel including, a cloth feeding teeth type steel, chain type steel, flat steel, round knife box, knife type steel, flat steel, square steel elliptical steel hook, ladder type steel, semi-circular steel, steel rack, elevator rail steel and so on, are materials production of textile machinery is indispensable.
