All stainless steels resist general corrosion by all concentrations of caustic soda
up to about 65C (150F). Other authorities give higher temperature limits for, for
example, 50% caustic, but these are probably influenced by other factors, such as
the presence of impurities in the caustic. Types 304 and 316 show low corrosion rates
in boiling caustic at concentrations up to nearly 20%. Type 316 has a better resistance
to pitting than type 304 in caustic solutions, especially if chlorides are present. The
low-carbon grades perform marginally better than the high-carbon grades because
of their resistance to sensitization. This means that 316L is a good choice for caustic
solutions as long as operating conditions are such that caustic SCC is not a problem.6
SCC of 304 and 316 grades occurs at around 100C (212F). An isocorrosion curve
in mpy for these grades is shown in Figure 13.6.40 This figure also shows the temperature
and concentration region where caustic SCC of these steels is likely.

你的65度在一个极限位置,你最好选316L
