Carbon Steel Plate

Depending on the carbon content and strength, carbon steel sheets have different grades.
There are low, medium and high carbon steel plates. The higher the carbon content, the more durable and stronger the plate will be. There are further sub-categories depending on thickness and application as well as the formation process. Typically carbon steel plates are available in thicknesses from 0.4 mm to 80 mm, widths from 1000 mm to 45000 mm and lengths up to 18 meters. However, the lengths are customizable, which helps customers to put them into various applications, and they can also be used to manufacture cold rolled steel coils.

Carbon steel plate standards

Carbon steel plate includes almost all common standards for steel plates.
1. ASTM A36 plate - the most common carbon steel plate standard
2. ASTM A283 Grades A, B, C - also the most common material used in carbon construction
3. ASTM A516 - for boiler, vessel steel plates
4. ASTM A537 - For fusion welded pressure vessel and structural steel plates in heat treated carbon steel plate.
5. ASTM A573 - A carbon manganese silicon structural steel plate.
6. ASTM A572 - ASTM A572 plate mechanical strength is higher than A36. where the weight is lighter.
7. ASTM A737 - low alloy steel plate used for boilers, pressure vessels.
Thus carbon steel plate has wide coverage for different types of steel plates in different industries.
