316Ti
and 304Ti VS 304 Stainless Steel
In this single-phase alloy,
titanium is added to Type 316 and 304 austenitic
stainless steel. The resultant titanium-stabilized
microstructure gives the alloy the ability to be
used at elevated temperatures for extended periods
of time without compromising its corrosion
resistance.
316Ti and 304Ti is recognized as
being more resistant to general corrosion than
basic 18Cr-8Ni stainless steels. 316Ti and 304Ti
has resistance to pitting corrosion caused by
chlorides (found in things such as table salt
(NaCl )) that is markedly better than basic
austenitic stainless steels such as regular Type
304.
This can be shown by comparing the
Pitting Resistance Equivalent (PRE) of 316Ti and
304Ti to that of 304 (Note: PRE is a relative
measure of pitting resistance used by the
metallurgical community.) The nominal PRE of 316Ti
and 304Ti is ~23.0, whereas the nominal PRE of 304
is ~19.0.
Another comparison which clearly
shows the superior pitting corrosion resistance of
316Ti and 304Ti is that Type 304 stainless steel
is considered to resist pitting corrosion in
waters containing up to ~100 ppm chloride, while
316Ti and 304Ti is considered to resist pitting in
waters containing up to ~2000 ppm chloride. Based
on such testings, this alloy is thus considered to
be “corrosion proof” for cooking.
All in all, the alloys used for
this new material exhibit outstanding
metallurgical properties, that, when fused
together to form the Solutions Ti material,
provide the basis for excellent performing
cookware.
