.Remarks: 304/304L/316/316L cold drawing bar are used in machine work .if the content of S is greater or equal to 0.015%. Steel grade is good performance in machinability. 17-4PH can not be cold drawing generally. Heat treatment can make reach the mechanical properties as chart 9 mechanical properties of clod drawing products
