1Cr18Ni9Ti, as a titanium-stabilized austenitic stainless steel (equivalent to 321), its performance advantages stem from the precise composition combination. 18% chromium is the core of corrosion resistance. It can quickly form a dense Cr₂O₃ oxide film on the material surface, which can resist the erosion of various acidic media and lay a solid foundation for the material's corrosion resistance. The 9% nickel element builds a stable austenite crystal structure, endowing the material with excellent low-temperature toughness. Even in an extremely cold environment of -180 ℃, it can still maintain good mechanical properties and prevent the component from brittle fracture due to low temperature. ​ The addition of titanium is the key difference between it and ordinary stainless steel. It can preferentially combine with carbon to form stable carbides, effectively preventing the precipitation of carbides at the grain boundaries during the welding process, fundamentally solving the problem of…
