Product details

This Square Billet 10x10in ASTM Gr.50 is a high-strength low-alloy structural steel that offers excellent performance for demanding structural projects. Its larger size compared to smaller billets allows for the creation of substantial components, while its specific chemical and mechanical properties make it suitable for withstanding heavy loads and undergoing various fabrication processes.

Parameter	Value	Remarks
Standard	ASTM A572/A572M	Standard specification for high-strength low-alloy columbium-vanadium structural steel
Grade	ASTM Gr.50	Known for its higher strength compared to many common structural steel grades
Chemical Composition (wt%)
– Carbon (C)	≤0.23	Plays a crucial role in balancing strength and weldability
– Silicon (Si)	≤0.40	Aids in deoxidation and influences the overall properties of the steel
– Manganese (Mn)	≤1.35	Enhances strength and toughness of the steel billet
– Phosphorus (P)	≤0.04	Kept at a low level to prevent brittleness and ensure good quality
– Sulfur (S)	≤0.05	Minimized to reduce the risk of cracking during processing
– Columbium (Nb)	≤0.05	Microalloying element that helps refine the grain structure and boost strength
– Vanadium (V)	≤0.08	Contributes to strengthening and improving mechanical properties
Mechanical Properties
– Yield Strength (Fy)	≥345 MPa (≥50 ksi)	Minimum yield strength to ensure it can bear significant loads in structural applications
– Tensile Strength (Fu)	450 – 620 MPa (65 – 90 ksi)	Determines the overall load-bearing capacity of the billet
– Elongation (in 200 mm, %)	≥18	Provides sufficient ductility for fabrication processes like bending, forging, etc.
– Bend Test	180°	Bend diameter is specified according to the relevant ASTM standards based on the thickness of the specimen
Dimensions	10 x 10 in (square cross-section)	Nominal size; there are allowable tolerance ranges as per ASTM standards for accurate manufacturing and quality control
Length	Customizable based on specific project requirements	Usually available in a range of lengths or can be cut to desired lengths to avoid material waste
Surface Quality	Generally required to be free from cracks, significant surface defects like deep scratches, and excessive scale	To meet the quality standards for further processing and usage in structural applications
Delivery Condition	Hot rolled, normalized, or thermomechanically controlled processed (TMCP)	Different delivery conditions can be chosen depending on the specific fabrication needs and performance expectations
Typical Applications	Structural components in large-scale infrastructure such as high-rise buildings, long-span bridges, heavy-duty industrial machinery frames, offshore platforms, and other applications where high strength and good workability are essential
