Parameter	Value	Remarks
Standard	ASTM A36/A36M	American Society for Testing and Materials standard for carbon structural steel
Grade	ASTM A36	Commonly used in general construction and structural applications
Chemical Composition (wt%)
– Carbon (C)	≤0.26	Affects strength and weldability
– Silicon (Si)	≤0.40	Helps in deoxidation and influences steel properties
– Manganese (Mn)	≤0.80 – 1.20	Enhances strength and toughness
– Phosphorus (P)	≤0.04	Kept at a low level to avoid brittleness
– Sulfur (S)	≤0.05	Minimized to reduce cracking risks during processing
– Copper (Cu)	≤0.20	May have some influence on corrosion resistance
Mechanical Properties
– Yield Strength (Fy)	≥250 MPa (≥36 ksi)	Minimum value to ensure structural stability under load
– Tensile Strength (Fu)	400 – 550 MPa (58 – 80 ksi)	Provides the overall load-bearing capacity
– Elongation (in 8 in., %)	≥20	Good ductility for fabrication and forming
– Bend Test	180°	Bend diameter: 1.5 times the thickness for specimens ≤ 1.5 in. thick
Dimensions	3.5 x 3.5 in (square cross-section)	Nominal size; allowable tolerances are specified in relevant ASTM standards
Length	Customizable depending on specific requirements	Usually available in certain standard lengths or can be cut to order
Surface Quality	Generally required to be free from cracks, deep scratches, and excessive scale	To meet the quality standards for further processing or application
Delivery Condition	Hot rolled, normalized, or as-rolled	Different delivery conditions can be chosen based on the intended use and fabrication needs
Typical Applications	Structural members in buildings, bridges, industrial equipment frames, storage racks, and general fabrication projects where moderate strength and good formability are needed
