Material for vessel containing methanol

Material for vessel containing methanol

(OP)
Would SS304 or SS316 be a better choice for a reactor containing 200 kg/hr sulphuric acid (97%), 2000 kg/hr methanol (98%) and 3500 kg/hr free fatty acids mixture? My initial choice was SS304 since the sulphuric acid amount was little, but upon reading more on methanol, I'm considering about using 316. Any suggestions on this?

The reaction is carried out at 75 C and 450 kPa.
