It exhibits the same high strength, toughness and workability as 304 alloys.
The moduli of elasticity used are 29,700,000 psi for steel and 10,000,000 psi for aluminum. The steel weights are tweaked for mechanical tubing, and will be less accurate for structural tubing. The calculated results will have the same units as your input. If the deflection is large enough to permanently bend the tube, then all bets are off. Rectangular tube is an extruded product that is widely used for all types of fabrication projects where lightweight and corrosion resistance is a primary. Round pipe: 8mm-165mm,rectangular tube:1020mm-50100mm,square tube. Enter below, the tube diameter D and thickness t. 1 Square Steel Tubing Strength Some tool steels are designed to resist deformation. Same excellent corrosion resistance as 316. This tool calculates the properties of a circular tube section (also called circular hollow section or CHS). The use of HSS is growing with popularity all around the world in the building industry and in the United States. In the United States, HSS sections conform to either the ASTM Specification A500 or A1085. 316 can be used for valves, marine equipment, pumps, and chemical equipment.Įxtra low carbon avoids harmful carbide precipitation due to welding. Hollow Structural Sections (HSS) are manufactured hollow steel sections, typically of circular, rectangular, or square cross-section. The deformation and mechanical property of rectangular tube periodic sandwich structure in quasi-static and low-velocity impact tests are deeply studied by. parameler used for truss connecUons as defined in Section 9.4 Qp parameler used for truss connecUons as defined in Secllon 9. Same corrosion resistance as 304 with lower mechanical properties.īetter pitting and corrosion resistance than 304, as well as higher strength at elevated temperatures. v, SPECIFICATION FOR THE DESIGN OF STEEL HOLLOW STRUCTURAL SECTIONS Q. One of the most commonly used grades across the industry.Įxtra low carbon avoids harmful carbide precipitation due to welding. In terms of tube diameters, the above formula is equivalent to: where the inner, hollow area diameter. Offers resistance to corrosion, has good formability and can be readily welded by all methods. Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance. Offers high weldability and is used frequently in structural applications in bridges and buildings as well as in both the automotive and appliance industry. Standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes.
