Under most conditions it can be taken that the two grades are interchangeable, 316L (316S11/1.4404) being suitable for applications where 316Ti (320S31/1.4571) is specified. In aqueous corrosion media or environments at ambient temperatures, there is no practical advantage in specifying the 316Ti type in preference to the 316L. In some circumstances the 316L (1.4404 / 1.4432) grades may be better choices.
