Product Description

ASTM A36 carbon steel:
A36 steel is one of the most commonly used structural steels worldwide due to its excellent weldability, machinability, and versatility. It is a low carbon steel with good strength, ductility, and formability, making it suitable for a wide range of applications in construction, manufacturing, and industrial sectors.

Chemical Composition:
Carbon (C): 0.25% (max)
Manganese (Mn): 0.60%-0.90%
Phosphorus (P): 0.040% (max)
Sulfur (S): 0.050% (max)
Silicon (Si): 0.40% (max)
Copper (Cu): 0.20% (min) if specified

Mechanical Properties:
Yield Strength: 250 MPa (36,000 psi) minimum
Tensile Strength: 400-550 MPa (58,000-80,000 psi)
Elongation: 20% (in 200 mm), 23% (in 50 mm) minimum
Brinell Hardness: 119-162 HB

Physical Properties:
Density: 7.85 g/cm³ (0.284 lb/in³)
Melting Point: Approximately 1425°C (2600°F)
Formability and Weldability:
A36 steel exhibits good formability, allowing it to be easily shaped, bent, or welded into various configurations without sacrificing its structural integrity. It can be welded using common welding methods, including arc welding, MIG welding, and TIG welding, with appropriate preheating and post-weld heat treatment.

Surface Finish:
The surface of A36 steel can be finished to various specifications, including:
Mill finish: As rolled, with a rough surface texture.
Hot rolled pickled and oiled (HRPO): Smooth surface finish achieved by pickling and oiling to remove scale and impurities.
Cold rolled: Smooth, matte surface finish achieved through cold rolling and annealing.

Applications:
Structural components: Beams, columns, channels, and angles in building construction.
Machinery parts: Frames, brackets, and base plates in manufacturing equipment.
Transportation equipment: Trailer frames, chassis, and truck beds.
General fabrication: Welded structures, platforms, and staircases.

Quality Assurance:
A36 steel is manufactured to meet ASTM A36/A36M standards, which specify the chemical composition, mechanical properties, and dimensional tolerances. Quality assurance measures include material testing, inspection, and certification to ensure compliance with industry standards.

Environmental Considerations:
Proper handling and disposal of scrap steel and by-products generated during manufacturing processes are essential to minimize environmental impact. Recycling of scrap steel is encouraged to conserve resources and reduce energy consumption.
