Carbon Steel Plate: Essential Information

 

Understanding Carbon Steel Plates

Carbon steel plates are primarily composed of iron and carbon, with minimal alloy elements. Common elements include carbon (C), manganese (Mn), phosphorus (P), sulfur (S), and silicon (Si). They do not have minimum limits for elements like aluminum (Al), chromium (Cr), nickel (Ni), molybdenum (Mo), or vanadium (V).

These plates come in various grades based on carbon content and strength. There are three main categories: low, medium, and high carbon steel plates. Higher carbon content increases the plate's durability and strength. Thickness ranges from 0.4 mm to 80 mm, width from 1000 mm to 4500 mm, and lengths up to 18 meters, though lengths can be customized. Cold-rolled steel coils can also be made from these plates.

Carbon Content Levels

  • Low Carbon Steel Plate: 0.06% to 0.25% carbon, also known as mild steel.
  • Medium Carbon Steel Plate: 0.25% to 0.55% carbon.
  • High Carbon Steel Plate: 0.55% to 1.0% carbon, also called hard steel.

Increased carbon content results in higher hardness.

Types and Uses of Carbon Steel Plates

Carbon steel plates have diverse applications across various industries. They are classified by carbon content and usage. Below are some common types:

  • Carbon Structural Steel Plate: Used mainly in construction, requiring high quality, durability, and corrosion resistance.
  • Boiler Steel Plate: High-pressure plates used in vessels, boilers, and heat containers. They have low corrosive properties and can withstand low heat.
  • Tanks Steel Plate: Used for constructing oil, gas, and storage tanks.
  • Carbon Shipbuilding Steel Plate: Essential in the oil and gas industry, made to customer specifications and certified for quality to prevent lamellar tearing.

Relevant Standards for Carbon Steel Plates

Carbon steel plates adhere to various standards:

  1. ASTM A36: Common standard for carbon steel plates.
  2. ASTM A283 Grade A, B, C: Widely used in carbon structural applications.
  3. ASTM A516: Used for boiler and vessel steel plates.
  4. ASTM A537: Heat-treated carbon steel for pressure vessels and structural applications.
  5. ASTM A573: Structural steel with carbon-manganese-silicon.
  6. ASTM A572: Offers higher mechanical strength than A36 with lower weight.
  7. ASTM A737: Low alloy steel for boilers and pressure vessels.
