IS 4923 or formerly referred to as BS 5950 is a standard that takes into consideration Sections of hollow steel intended for use in structural applications. Although any process could be used to produce the Seamless Square Pipe, there are certain restrictions with regards to their chemistry. For instance, the alloy used to make a Seamless Rectangular Tube must not contain more than 0.040% of both Sulphur as well as Phosphorus.
On the other hand, welded hollow sections of this particular specification are mandated to be manufactured from hot rolled steel strip, which in turn will conform to specification IS 10748. Steel alloys like ST 52 is a low alloyed, high strength grade steel. The high tensile strength properties of ST 52 Seamless Hollow Bar is what classifies this particular grade as a structural steel alloy. The low content of carbon present in the IS 4923 Steel hollow section is what gives the alloy good weldable properties. The chemistry of the product in addition to mechanical properties and ease in maintenance of BS 5950 square hollow section makes it one of the more sought after products. The applications of this structural steel is noted in industries like oil and gas for the transportation of fluids or other gaseous media. To improve the life of the product, the Seamless Hollow Section is regularly treated with an anti-corrosion heat preservation or by the use of varnish to coat its surface.
