"AISI 304 stainless steel has good corrosion resistance in industrial and marine atmosphere. It resists almost all corrosion agents used in industry. It is easily welded. It can be welded with non-ferrous metals (lead-tin, silver-based alloys, etc.). However, overheated areas should be subjected to hypertemper to improve corrosion resistance. It is not temperable and can be hardened by cold deformation, in an annealed (hypertempered) state it is not ferromagnetic. By cold deformation it acquires ferromagnetism as the rate of deformation increases. It has regular machinability. To machine, it is necessary to use high quality tools that correctly make the cut bojo the high pressures that occur in the machining. (Sintered carbides)."
