Product Description

Carbon steel is the earliest and most used basic material in modern industry. While the industrial countries in the world are striving to increase the output of low-alloy high-strength steel and alloy steel, they also pay great attention to improving the quality of carbon steel and expanding the variety and scope of use.

At present, the output of carbon steel accounts for about 80% of the total output of steel in various countries. It is not only widely used in construction, bridges, railways, vehicles, ships and various machinery manufacturing industries, but also in the modern petrochemical industry. , marine development, etc., have also been widely used.

Iron-carbon alloys containing less than 2.11% carbon and containing no other alloying elements except for impurities such as iron, carbon, and limited amounts of silicon, manganese, phosphorus, and sulfur. The carbon content of industrial carbon steel is generally 0.05%~1.35%. The performance of carbon steel mainly depends on the carbon content. As the carbon content increases, the strength and hardness of the steel increase, while the plasticity, toughness and weldability decrease. Compared with other steels, carbon steel is used the earliest, with low cost, wide performance range and the largest consumption. It is suitable for media such as water, steam, air, hydrogen, ammonia, nitrogen and petroleum products with a nominal pressure PN≤32.0MPa and a temperature of -30-425°C. Commonly used grades are WC1, WCB, ZG25, high-quality steel 20, 25, 30 and low-alloy structural steel 16Mn.
