Cold drawn steel bar is produced by Hot Rolled Steel Bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.
For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.
To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).
For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.
We have more advantages on producing cold drawn steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty

In the past few years, the entire world has witnessed a strong demand for analytical instruments and automated products. As a result, the United States has played a leading role in further strengthening market potential. Well-known companies in this industry have adopted high standards. Investment, strict compliance with regulations, and product innovations have effectively increased their company's revenue. Although the 2009 economic recession has slowed down the growth of the analytical instrument market, the subsequent post-recession period is likely to increase end-user spending.
In 2011, the size of the US analytical instrument market is expected to reach US$6.6 billion. According to the above developments, the US analytical instrument market is expected to reach US$7.3 billion by 2014.
Among them, the growth of this market depends to a large extent on several industries, such as chemicals, food and beverages, oil and gas, electric utilities, medicine, etc. Since most of these industries operate well and capital expenditures are mostly effective, The quality monitoring of these industries will promote the development of the overall market for analytical instruments. In addition, instrument procurement by the government to ensure social security is still at the forefront of all industries.
Current mainstream products in the US analytical instrument market include gas analysis instruments, liquid analysis instruments, final control elements, electronic flow meters, and control systems. In 2011, these instruments together accounted for about 70% of the total market. In addition, the government's relevant regulatory measures in environmental safety, food safety, chemical plants, and pharmaceutical production will become the main drivers of these subdivided instrument markets.
