High-Si steel is a low cost alternative for the fabrication of tubular structures resistant to atmospheric corrosion. However. the literature has often pointed out that steels presenting a higher Si content and/or a lower Mn/Si ratio have higher susceptibility to defects at the weld bond line during HFIW (High Frequency Induction Welding) process. which has been widely used for manufa... https://www.roneverhart.com/Katin-Mens-Jacket-Harold-Corduroy/
