Surgical Stainless Steel Cookware
304 vs 316
We, in an effort to
try and distinguish ourselves from our competition
are promoting the fact that we use 316 surgical
stainless steel with Titanium, rather than 304
surgical stainless steel. In the chart below is a
direct comparison between 304 and 316 surgical
stainless steel.

Summary of
differences:
1. 304 may have a
higher Chromium content than 316 but not
necessarily.
2. 316 may have a
higher Nickel content but not necessarily.
3. We do not use
Molybdenum in our composition. We use Titanium.
What is 316 better
for than 304? 316 is preferred over 304 for marine
hardware where it is exposed to extreme harsh sea
salt conditions 24 hours a day 7 days a week. It
lasts longer than 304 in this application.
Anywhere where there
is exposure to concentrated sodium chloride
conditions 316 is preferred over 304. If you are
going to put 1 cup of sodium chloride (table salt)
in your cookware with 4 oz. of water on a daily
basis you may benefit from using 316 over 304.
We have established
over 500.000 clients over the last 45 years with
304-T surgical steel cookware and have now
upgraded to 316T surgical stainless steel with
Titanium.
Instead of Molybdenum
our cookware uses Titanium as a hardening alloy.
Titanium is about six times as expensive as
stainless steel.
Originally designed
to produce strong lightweight alloys for
aerospace, the two most useful properties of the
metal form are corrosion resistance and the
highest strength-to-weight ratio of any metal.
Stronger than steel but 45% lighter.
