ASTM A500 Grade B Tubes Introduction ASTM A500 is a standard specification issued by ASTM International for cold-formed welded and seamless carbon steel structural tubing. These tubes are widely used in construction and structural applications due to their excellent strength, weldability, and cost-efficiency. Grade B is one of the most commonly used grades within this specification, offering a good balance of strength and ductility. Sizes and Range ASTM A500 Grade B tubing is available in different shapes: Round Square Rectangular Typical Size Range: Outside Diameter (OD): Round tubes: 0.5“ to 16” Square tubes: 0.5“ x 0.5” to 12“ x 12” Rectangular tubes: various combinations up to 12“ wide and 8” deep Wall Thickness: 0.065“ to 0.875” (varies by shape and OD) Length: Standard lengths are 20', 24', 40', and 48', though custom lengths can be produced. Chemical Composition (Max % by weight) Carbon (C) 0.26% max Manganese (Mn) 1.35% max Phosphorus (P) 0.035% max Sulfur (S) 0.035% max Copper (Cu)* 0.20% min (if copper steel is specified) Note: Copper content is optional unless specified for enhanced corrosion resistance. Mechanical Properties Property Requirement (Grade B) Yield Strength ≥ 46,000 psi (317 MPa) Tensile Strength ≥ 58,000 psi (400 MPa) Elongation Varies with shape and size (usually 23% or more in 2") ASTM A500 Grade B tube supplier ASTM A500 Grade B tube manufacturer ASTM A500 Grade B structural tubing ASTM A500 Grade B steel tube Buy ASTM A500 Grade B tubes ASTM A500 Grade B rectangular tubing ASTM A500 Grade B square tube ASTM A500 Grade B round tubing ASTM A500 Grade B steel tubing suppliers in Mumbai Wholesale ASTM A500 Grade B tubing manufacturers ASTM A500 Grade B tube price per foot Cold formed ASTM A500 Grade B tubing suppliers ASTM A500 Grade B steel pipe distributor Exporter of ASTM A500 Grade B steel tubes High-strength ASTM A500 Grade B tubes for construction If you have any requirement, please email us on sales@sagarsteel.net or call us on +91 9920177883
