The welding procedure on this pipe is essential to have preheat treatment and post weld heat treatments. The ASME SA 312 Grade 309h Square Pipe is stronger due to the shape. There are hot rolled, cold rolled, seamless and welded pipes in this grade of material. There is also a lower carbon version of the pipes known as 309s. The UNS S30909 schedule 40 pipe and other pipes are used in furnaces, kilns, combustion changers and burners which are all high temperature and high corrosive applications. Please feel free to contact us for the full price list and more details of the DIN 1.4833 AISI 309h Rectangular Pipe.
