Cold rolled coil is made of hot rolled coil and rolled be- low recrystallization temperature at room temperature, including plate and coil. Many domestic steel mills such as Baosteel, WISCO and Angang can produce them.
Carbon steel sheet is an iron carbon alloy with carbon content of 0.021 8% ~ 2.11%. Generally, it also contains a small amount of silicon, manganese, sulfur and phosphorus.
Durable - carbon steel is very strong and shock resisntant. Safety-green carbon steel is easy ro recycle, mak- ing it environment-friendly. Economy-carbon steel is cheaper than copper pipe.
Mild carbon steel is generally used in oil pipelines. Medium carbon steel fluid transportation and mechanical manufacturing can involved. High carbon steel is usually applied in machining.
