That doesn't make any sense. From my sources 416 is the cheaper
stainless. I buy 303 for best machinability, 416 for machinable and
high strength and price, and 304 if I have to have it today because
that's all the local yards stock. Occasionally I'll buy 316 for special
applications.

Hummm...let me check on this. Ive read a number of studies that
claimed..claimed 416 was superior to strength and corrosion resistance
in sal****er. So Ive been using just about all 416 to machine parts
for the sailboats I restore. I think I had Better check on this...

I don't know about its corrosion resistance persaye. Just that its
cheaper than any of the other common stainless alloys I can buy from my
regular vendors.

I always thought 316 was the most corrosion resistant of the common
alloys and 303 was the least. There is also a 316L which is slightly
more machinable than 316, but not as easy as 416.
