1、 Definition of Cold drawn Steel

The so-called cold drawn steel, also known as cold drawn steel, refers to materials made by processing steel through drawing process at room temperature. It involves a series of processing techniques such as drawing, drilling, softening, etc. on steel to improve its surface smoothness, dimensional accuracy, mechanical properties, etc., thereby achieving the effect of refining grains and improving microstructure.

2、 Production process

The production process of cold drawn steel is relatively complex and requires multiple stages. Common production processes include the following steps:

1. Selection of raw materials for steel ingots and heat treatment of materials;

2. Pre processing and preparation of steel ingots;

3. Cold working process, including wire drawing, boring, milling, quenching, etc;

4. Heat release treatment and sample testing;

5. Quality inspection of processed steel;

6. The production and packaging of steel.

3、 Characteristics and application areas

Cold drawn steel has the following characteristics:

1. High surface smoothness and good dimensional accuracy;

2. High mechanical strength and good ductility;

3. Good machinability, suitable for making precision components;

4. It has low density, light weight, and good wear and corrosion resistance.

Due to the complex manufacturing process of cold drawn steel, its price is generally higher. It has a wide range of applications, mainly in automotive parts, precision mechanical parts, building materials, bearings, springs, nuts, bolts, wall hooks, nails, and so on.

In short, cold drawn steel has excellent mechanical and physical properties and is widely used in various fields of manufacturing.
