1. ER308 is an austenitic stainless steel welding wire, which is specially used for welding austenitic stainless steel 304. It can also be used for surface stainless steel surfacing and other occasions with low alloy composition requirements. When welding stainless steel or clad steel, it is necessary to determine the corresponding welding materials first.
2. Austenitic stainless steel electrode means that in addition to welding the corresponding austenitic stainless steel, it can also be used as a welding material for clad steel, dissimilar steel, and carbon steel with a large quenching tendency and high-chromium steel. Solid metals and alloys are all crystals, and their internal atoms are arranged according to certain rules. There are generally three types of arrangement, namely body-centered cubic lattice structure, face-centered cubic lattice structure, and close-packed hexagonal lattice structure.
3. Austenitic stainless steel refers to stainless steel with an austenitic structure at room temperature. When the steel contains about 18% Cr, 8%~10% Ni, and about 0.1% C, austenitic stainless steel is non-magnetic and has high toughness and plasticity, but the strength is low, and it is impossible to strengthen it through phase transformation. Cold working for strengthening.
