EN 10219 S275JOH Hot Finish Rectangular Hollow Section Welded Tube

This grade of hollow sections is known for its cheap cost compared to most steel pipes. It also has a low carbon content. Hence, these square hollow sections are a very affordable alternative. From a chemical point of view, the maximum carbon concentration of S355JOH sections produced by the factory is 0.22%. Hence, these hollow tubes are easily formed through the hold-finish process. The length of the hollow sections ranges from 6000mm to 18000mm, and special cut-to-length sizes are also available. The substance is often used in a variety of structural, mechanical, and architectural applications.
S355JOH steel hollow sections for rectangular tube types range from 40mm*20mm to 400mm*200mm. Carbon, silicon, manganese, and phosphorus are the main elements of this material. Since S355JOH sections are low carbon steel, they can be welded without intergranular corrosion; however, it is recommended to use adequate filler material, preheating, and post-weld heat treatment when using certain welding techniques to prevent weld cracking. S355JOH RHS is available in a wide range of configurations with wall thicknesses ranging from 1.8mm to 14.27mm and ODs from 21.3mm to 457.2mm. Good mechanical properties, good strength and good weldability.
Applications for this grade of round hollow sections include marine and power plant industries, offshore, electrical and many more. These sections have an OD range of 21.3mm to 457.2mm. The technical delivery requirements outlined in the European Standard apply to hot finished S355JOH round hollow sections manufactured in a variety of ways and they can be applied to sections that have been hot formed, with or without further heat treatment. These spherical hollow sections can be cold formed after heating to successfully achieve a metallurgical state comparable to the hot formed output.
