Grade:TA1,TA2,TA3,TA4,TC4,TA9,TA10. Grade:Gr1,Gr2,Gr3,Gr4,Gr5,Gr7,Gr9,Gr10. Standard:GB/T 2965. Standard:ASTM B348. Supply status: hot processing state (R), cold processing state (Y), annealing state (M). Shape; round bar, square bar, hexagonal bar. Surface treatment: shiny, polished, black skin. Manufacturing process: Hot forging-hot rolling-vehicle (grinding). Product characteristics: the strength, not high, but good plasticity, easy to process, stamping, welding, cutting performance is good; in the atmosphere, seawater, wet chlorine gas and oxidation, neutral, weak reducing medium has good corrosion resistance, oxidation resistance is better than most austenitic stainless steel; but the heat resistance is poor, the use temperature should not be too high. Main uses: aircraft skeleton, skin, engine accessories, pipes, valves, pumps and fins, seawater desalination system components; chemical heat exchangers, pump bodies, distillation towers, coolers, mixers, links, impeller, fasteners, ion pumps, compressor valves, diesel engine pistons, connecting rods, leaf springs, etc.
