Product Details
Grade 316Ti SMLS Stainless Steel Seamless Pipe
316Ti (1.4571) SEAMLESS&WELDED PIPE
316Ti (UNS S31635) is a titanium stabilised version of 316
molybdenum-bearing austenitic stainless steel.
The 316 alloys are more resistant to general corrosion and
pitting/crevice corrosion than the conventional chromium-nickel
austenitic stainless steels such as 304. They also offer higher
creep, stress-rupture and tensile strength at elevated temperature.
High carbon Alloy 316 stainless steel can be susceptible to
sensitisation, the formation of grain boundary chromium carbides at
temperatures between approximately 900 and 1500°F (425 to 815°C)
which can result in intergranular corrosion. Resistance to
sensitisation is achieved in Alloy 316Ti with titanium additions to
stabilise the structure against chromium carbide precipitation,
which is the source of sensitisation. This stabilisation is
achieved by an intermediate temperature heat treatment, during
which the titanium reacts with carbon to form titanium carbides.
This significantly reduces susceptibility to sensitisation in
service by limiting the formation of chromium carbides. Thus, the
alloy can be used for extended periods at elevated temperatures
without compromising its corrosion resistance. 316Ti has equvilent
corrosion resistance to sensitisation as the low carbon version
316L.

ADVANTAGES OF WELDED
- Welded pipes are typically more cost effective than their seamless
equivalents.
- Welded pipes are usually more readily available than seamless. The
longer lead time required for seamless pipes can not only make
timing problematic, but it also allows more time for the price of
the materials to fluctuate.
- The wall thickness of welded pipes is generally more consistent
than that of seamless pipes.
- The internal surface of welded tubes can be checked before
manufacturing, which isn’t possible with seamless.
ADVANTAGES OF WELDED
- The main perceived advantage of seamless pipes is that they don’t
have a weld seam.
- Seamless pipes provide peace of mind. Although there should be no
issues with the seams of welded pipes supplied by reputable
manufacturers, seamless pipes prevent any possibility of a weak
seam.
- Seamless pipes have better ovality or roundness, than welded pipes.
