– Austenitic basic steel, the most widely used;
– Excellent corrosion resistance and heat resistance;
– Excellent low temperature strength and mechanical properties; – Single-phase austenitic structure, no heat treatment hardening phenomenon Compared with 304 excellent corrosion resistance. Uses -1, 2 kinds of tableware, exterior materials, building materials, auto parts, – Medical devices, chemistry, food technology, fiber industry, – Ship parts – Chemical, coal, oil industry equipment with high resistance to grain boundary corrosion, – Building materials, heat-resistant parts and components that are difficult to heat-treat
