RE: SS 304L for NITRIC ACID(68%STRENGTH)

304L will do fine. Sedricks ( Corrosion of Stainless Steel) gives the corrosion rate at less than 0.005 inch/year at 90C. At room temperature, there's not anything measurable to worry about.

RE: SS 304L for NITRIC ACID(68%STRENGTH)

Schweitzer says less than 0.002 inches per year at room temperature.
