Product details

This Square Billet 5x5in ASTM A36 is a popular choice in the construction and manufacturing industries due to its well-balanced mechanical properties and workability. Its larger size compared to some other billets allows for the creation of more substantial structural components while still maintaining the ease of processing associated with ASTM A36 grade steel.

It should be noted that the actual performance may vary slightly depending on different manufacturers’ production processes and quality control measures.

Parameter	Value	Remarks
Standard	ASTM A36/A36M	Standard specification for carbon structural steel by ASTM
Grade	ASTM A36	Commonly used in various structural and construction applications
Chemical Composition (wt%)
– Carbon (C)	≤0.26	Influences strength and weldability; controlled to ensure proper balance
– Silicon (Si)	≤0.40	Aids in deoxidation and impacts the overall properties of the steel
– Manganese (Mn)	≤0.80 – 1.20	Enhances strength and toughness, crucial for structural integrity
– Phosphorus (P)	≤0.04	Kept at a low level to avoid brittleness and poor performance
– Sulfur (S)	≤0.05	Minimized to reduce the risk of cracking during fabrication processes
– Copper (Cu)	≤0.20	May contribute to improved corrosion resistance to some extent
Mechanical Properties
– Yield Strength (Fy)	≥250 MPa (≥36 ksi)	Minimum value to ensure the billet can withstand loads without excessive deformation
– Tensile Strength (Fu)	400 – 550 MPa (58 – 80 ksi)	Determines the overall load-bearing capacity in structural applications
– Elongation (in 8 in., %)	≥20	Provides good ductility for processes like bending, forging, etc.
– Bend Test	180°	Bend diameter: 1.5 times the thickness for specimens ≤ 1.5 in. thick
Dimensions	5 x 5 in (square cross-section)	Nominal size; there are allowable tolerance ranges as per the relevant ASTM standards
Length	Customizable according to specific requirements	Usually supplied in certain lengths but can be cut to specific lengths as per customer orders
Surface Quality	Generally required to be free from cracks, significant surface defects like deep scratches, and excessive scale	To meet the quality requirements for further processing or application
Delivery Condition	Hot rolled, normalized, or as-rolled	Different delivery conditions can be chosen based on specific fabrication needs and usage scenarios
Typical Applications	Structural components in buildings, bridges, large industrial frames, heavy-duty storage racks, and other applications where relatively larger sections of structural steel with good strength and workability are needed
