Suzhou cold drawn steel, it is a kind of steel, after cold drawing processing, can form a variety of shapes and sizes. Itin the car, hardware, machinery, textile and other industries, widely used. Probably understand the concept andapplication of Suzhou cold drawn steel, let's talk about its classification and some common defects.

1 Classification

Suzhou cold drawn steel can be divided into cold drawn steel, cold drawn steel, cold drawn flat steel, cold drawn andcold drawn shaped steel, six angle steel.

2 common defects

Common defects of Suzhou cold drawn steel mainly has the following these, as:

(1) indentation and roll mark: is on the surface there are rules or irregularly distributed with indentation and roll mark,is mainly composed of roll breakage or roll are stuck on the body caused by.

(2): scratches and grooves in cold drawn steel on mechanical damage, basically is parallel or perpendicular to thedirection of rolling.

(3) and skin: surface defect scaly is refers to the irregular, along the rolling direction of extension, its degree isrelated with the amount of deformation.

(4): in the hot bubble will appear, which are mainly caused by degassing bad.

(5): is the inclusion surface with non-metallic insert, is generally random distribution, its color and the matrix is different, generally in the smelting, casting process into inclusion, caused this phenomenon.

(6) the crack: crack appeared on the surface, which is caused mainly by stress.
