Abstract:
TLA-OHF (20Mn23AlSiMoTi) belongs to C-Mn-Fe austenitic steel, which is characterized by good toughness, excellent non-magnetic properties, ~and has certain high temperature resistance, oxidation resistance, ~and no intergranular corrosion cracking. The cost is relatively low, ~and the overall comprehensive cost performance is higher than that of stainless steel. It is the preferred material for the steel used in the furnace of the submerged arc furnace.
