ASTM A36 steel plate is an American standard carbon structural steel, implemented according to ASTM A36/A36M. The following is a detailed introduction:

Chemical Composition: Carbon (C) ≤ 0.25%, Silicon (Si) ≤ 0.40%, Manganese (Mn) 0.80%-1.20%, Phosphorus (P) ≤ 0.04%, Sulfur (S) ≤ 0.05%, Copper (Cu) ≥ 0.20% (when copper-containing steel is specified).

Mechanical Properties: 

Yield Strength ≥ 250 MPa (some data may reach 360 MPa, which may decrease with increasing thickness); Tensile Strength 400 MPa-550 MPa; Elongation ≥ 20% (some data may be ≥ 23%). Furthermore, the impact energy is ≥ 27 J at -20°C, making it resistant to brittle fracture at low temperatures.

Performance

Excellent Processability:

 Easy to cut, drill, weld, and form, it can be joined using various welding methods, including arc welding, gas welding, and resistance welding, with excellent joint performance. Moderate Strength and Toughness: It offers a high load-bearing capacity, meeting the load-bearing requirements of general structures. It can also undergo significant plastic deformation before fracture, contributing to improved structural toughness and safety.

Good Corrosion Resistance: Controlled chemical composition, such as low phosphorus and sulfur content, reduces the risk of corrosion. Surface treatment allows for adaptability to a variety of environments.

Delivery Condition: 

The default delivery condition is hot-rolled, but controlled-rolled, normalized, or normalized-rolled delivery conditions can be selected based on customer needs to meet varying performance requirements.

Applications

Construction: 

Used in the manufacture of load-bearing components such as beams, columns, steel plates, and steel frames for buildings. It is also commonly used in bridge construction, such as highway and railway bridges.

Machinery: 

Used in the manufacture of large motors, housings and bases for various pumps, as well as bearing seats, gears, mining equipment, excavators, cranes, and other mechanical components.

Transportation: 

Suitable for the manufacture of ship hulls, chassis, automotive structural components, and highway guardrails.

Other Applications: It can also be used in agricultural machinery, mining equipment, and other fields.

ASTM A36 steel plate is a flat sheet of steel produced by pouring molten steel and pressing it after cooling.

It is a flat, rectangular plate that can be directly rolled or cut from wide steel strip.

Steel plate is categorized by thickness as follows: thin plate <4 mm (thinnest 0.2 mm), medium-thick plate 4-60 mm, and extra-thick plate 60-115 mm.

Steel plate is categorized by rolling process into hot-rolled and cold-rolled.

Thin plate widths range from 500 to 1500 mm; thick plate widths range from 600 to 3000 mm. Thin plate is categorized by steel type, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel, and industrial pure iron. It is categorized by specialized application, including oil drum plate, enamel plate, and bulletproof plate. Surface coatings include galvanized sheet, tinned sheet, lead-coated sheet, and plastic-clad steel.
