Carbon steel sheets and plates are flat-rolled products composed mainly of iron and carbon, with small percentages of other elements like manganese, silicon, and copper. The carbon content is the primary determinant of the steel's properties.
Carbon Steel Sheets & Plates: Composition and Properties
Steel Sheets: Typically have a thickness of less than 6 mm (0.236 inches).
Steel Plates: Generally thicker than 6 mm (0.236 inches).
Carbon Content: Carbon steel is broadly classified based on its carbon content:
Low Carbon Steel (Mild Steel): 0.05% to 0.25% carbon. Known for its high ductility, toughness, machinability, and weldability. It is relatively low in cost and easy to form.
Medium Carbon Steel: 0.25% to 0.60% carbon. Offers a balance of strength and ductility, with improved hardenability compared to low carbon steel.
Common Carbon Steel Grades for Sheets & Plates
Several standard grades of carbon steel are used for sheets and plates, each with specific properties and applications. Some common examples include:
ASTM A36: A common structural steel grade, known for its good weldability, ductility, and strength. Widely used in construction for beams, columns, and various structural components.
ASTM A283: A low to medium tensile strength carbon steel used for general structural purposes. Available in different grades (A, B, C, D) with varying strength levels.
ASTM A572: A high-strength, low-alloy steel with good weldability and formability. Often used in construction and heavy machinery where higher strength-to-weight ratio is required.
ASTM A516: A carbon steel primarily for pressure vessels and boilers, especially for lower-temperature service. Available in different grades (55, 60, 65, 70) with increasing tensile strength.
IS 2062: An Indian Standard for hot-rolled medium and high-tensile structural steel. Grade B is a common designation with good tensile and yield strength, suitable for various structural applications.
SAE/AISI 10xx series: These grades are designated by a four-digit number where the last two digits indicate the carbon content in hundredths of a percent (e.g., 1010 has approximately 0.10% carbon, 1045 has approximately 0.45% carbon). These steels offer a range of properties depending on the carbon content, from formable (1008, 1010) to higher strength (1045, 1070) and spring steel grades (1095).
Applications of Carbon Steel Sheets & Plates
Carbon steel sheets and plates are fundamental materials in numerous industries due to their strength, versatility, and cost-effectiveness:
Construction: Structural frameworks for buildings, bridges, reinforcement in concrete, roofing, cladding, and fabrication of building components like doors, window frames, and staircases.
Manufacturing: Machinery parts, automotive body panels and chassis components, storage tanks, pressure vessels, shipbuilding, and various industrial equipment.
Transportation: Rail cars, truck frames, and components for heavy equipment.
Energy: Pipelines, storage tanks, and components for power generation facilities.
Automotive: Body panels, chassis, and structural parts.
Appliances: Housings and structural elements for various household and industrial appliances.
Tool and Die Making: High carbon steel is used for cutting tools, springs, and dies due to its hardness and wear resistance.
The specific grade of carbon steel sheet or plate is selected based on the application requirements, considering factors like strength, ductility, weldability, corrosion resistance (which is generally lower than stainless steel or aluminum), and cost. Surface treatments like galvanizing or painting are often applied to enhance corrosion resistance.
