Additional Information on 316L Stainless Steel
Another widely used austenitic steel is 316 and 316L stainless
steel, the corrosion performance of SS 304 is not enough, 316L is
often consider as the first alternate. The higher Nickel content in
316 and 316L over SS 304 and the Molybdenum addition in 316 and
316L gives it an edge in performance in corrosive and high
temperature environments.
As with 304 and 304L, the difference between the 316 and 316L
grades is the quantity of carbon contained. The L stands for low
carbon, both L grades contain a maximum 0.03% carbon, while the
standard grades can comprise up to 0.07% carbon. It may not seem
like a big difference, but it means that L grade versions of
stainless steel alloys suited better for the larger welding
projects. The lower Carbon content of L grades reduces cracking in
the heat affected zones of welds and improved weld quality.
Stainless Steel 316 Chemical Composition – Chrome and Nickel
As with the 304 grade, 316 stainless steel owes much of its
corrosion resistance to its chromium content. The passivated
chromium oxide film which develops on the surface acts as a
protective barrier against corrosion. It’s the chromium in the 304
and 316 grades that differentiate stainless steel from carbon
steel.
The chemical composition of stainless steel 316 is almost identical
to that of the 304 grade. There are a few distinct differences with
the quantities of chromium (18 – 20% for 304, 16 – 18% for 316) and
nickel (8 – 10.5% for 304, 10 – 14% for 316).
Production Spec.
Weathering steel(corten steel) is best known as "COR-TEN", which is abbreviated as "Corrosion resistance" and "Tensile strength" , so it is often referred to as "Corten Steel" in English. Unlike stainless steel, which can be completely rust-free, weathering steel is only oxidized on the surface and does not penetrate deep into the interior, and has anti-corrosion characteristics like copper or aluminum.
