Material classification of stainless steel pipe

Stainless steel pipes can be divided into CT series (400 series), Cr-N series (300 series), Cr-Mn-Ni (200 series), and precipitation hardening series (600 series) according to the composition. 200 series – chrome-nickel-manganese austenitic stainless steel 300 series – chromium-nickel austenitic stainless steel. 1. 301—–Good ductility, used for molding products. It can also be hardened by […]

The basic principles for the selection of welding consumables, considering the spatial position of the weld

Some welding consumables are only suitable for welding at a certain position, and the welding effect at other positions is poor. Some welding consumables can be welded at various positions, and the characteristics of the welding position should be considered when selecting.
