According to the provisions of GB700-88, the grade of ordinary carbon steel is expressed by the minimum yield strength of the steel. Although this type of steel contains a lot of harmful impurities and non-metallic inclusions, its smelting method is simple, the manufacture ability is good, the price is low, and its performance can also meet the requirements of general engineering structural parts and ordinary parts, so it is used in a large amount. , accounting for about 80% of the total steel.

The grade of steel is composed of the first letter “Q” in the Chinese pinyin of the word “Qu” representing the yield point, the yield point value (number), the quality grade symbols A, B, C, D, symbols such as deoxidation methods (using deoxidation methods, etc. The first letter of the name in Chinese Pinyin indicates, such as boiling steel (F), semi-killed steel (b), killed steel (Z), special killed steel (TZ)). The “Z” and “TZ” symbols can be omitted. For example, Q235-A·F stands for carbon structural steel, the yield point value is 235MPa, and it is grade A boiling steel.

Specification of Ordinary Carbon Steel Pipe and Tube

2. The steel bar can be divided into hot rolling, forging and cold drawing. The specification of hot rolling steel bar is from 5.5 to 250mm.

3. The steel pipe has the hollow section, its length is far bigger than it's diameter and perimeter. It can be divided into round, square, rectangle and hexagonal steel pipe according to the cross-section shape. And according to different material, it can be divided into carbon structure steel pipe, low alloy structure steel pipe, alloy steel pipe and complex steel pipe. And it can be divided into seamless steel tube and welded steel tube according to different manufacturing technology. And seamless tube can be divided into hot rolling and cold rolling while welded tube divided into straight slit welding and spiral seam welding tube.
