High Carbon Steel Coil Sheet Plates ASTM A36 Hot Rolled Carbon Steel Coil0.2mm 30-275g S275jr 0.5mm 1mm Low Carbon Mild Steel Coil
What are the types of carbon steel?
1. Carbon structural steel:
Main uses: all kinds of engineering. Usually supplied by air cooling after hot rolling, Users generally do not need to heat treatment and direct use. There are five grades of this steel according to their yield strength. Grade symbols: A, B, C, D (GradeD reaches the level of high quality steel)
2. High quality carbon structural steel:
Main uses: important parts. The mechanical properties of parts can be adjusted by heat treatment Commonly used brands: 08F, 10#, 15#, 20#, 35#, 45#, 60#, etc
3. Carbon tool steel (WC=0.65%~1.35% is high carbon steel) :
Main uses: making various small tools. High hardness and wear resistance can be obtained by quenching and low temperature tempering. It is divided into two categories of high quality and high quality.
4. General engineering cast carbon steel (cast steel) :
Main uses: difficult to be formed by forging and pressing and other methods of complex parts and high mechanical properties requirements;
