Stainless Steel Grade, Gauge Thickness & Drainage

Question:

We need a tank for heating cutting oil. Do you know what grade of stainless steel is used and the gauge thickness? Is there a drainpipe that can empty the contents from the inside tank?

Answer:

They are made of 304 stainless, 24 gauge. There is a 1.5″ diameter, 6″ long, outlet nipple that is also stainless. This drains the inside tank.
