ASTM A36 (Carbon Structural Steel Plate for General Fabrication) ASTM A36 is a widely used carbon steel grade recognized for its versatility, affordability, and ease of fabrication. Designed under the ASTM standard, A36 offers a minimum yield strength of 250 MPa (36 ksi) and is ideal for a wide variety of construction and general manufacturing applications. Its low carbon content ensures excellent weldability and machinability, making it a popular choice for both light and moderate structural work. From structural beams to general-purpose fabrications, A36 delivers dependable mechanical performance and is easy to process using conventional fabrication techniques. Key Features: 250 MPa yield strength suited for light to moderate load-bearing applications Exceptional weldability with no need for special welding procedures High formability and machinability, suitable for shaping and fabrication Cost-effective solution with wide availability and standard sizing Typical Mechanical Properties: Property ASTM A36 Yield Strength ≥ 250 MPa (36 ksi) Tensile Strength 400–550 MPa (58–80 ksi) Elongation ≥ 20% Impact Resistance Moderate Weldability Excellent Common Applications: Building frames, bridges, and civil construction elements Base plates, channels, angles, and standard structural sections Fabricated parts, industrial equipment bases, and machine platforms Storage tanks, supports, frames, and mild-load structures General manufacturing and custom steel fabrication Summary: ASTM A36 remains one of the most widely used carbon steel grades for structural and fabrication needs. Its combination of affordability, workability, and dependable mechanical properties make it a go-to material for engineers and fabricators around the world.
