A182 F316L Stainless Steel SORF Flange for Oil&Gas
Application
Grade 316L, the low carbon version of F316L pipe flange has immunity against sensitisation, otherwise known as grain
boundary carbide precipitation. Thus, the Gr F316L is extensively
used in heavy gauge welded components, where the wall thickness can
be over 6mm. The austenitic structure in the astm a182 f316l also
gives this grades excellent toughness properties ,that can be
witnessed at to cryogenic temperatures.
As compared to other chromium-nickel austenitic stainless steels,
A182 F316L stainless steel offers a much higher creep strength,
stress to rupture strength and tensile strength, even at elevated
temperatures. The ss 316L flanges have an excellent performance in
a broad range of atmospheric environments as well as many corrosive
media.
Generally the werkstoff A182 F316L tends to be more resistant to
corrosive media when compared to grade 304 stainless steel.
Although these stainless steel 316L flanges are a subject to
pitting & crevice corrosion in warm chloride environments, and
to stress related corrosion cracking at temperatures above 60 °C,
sa 182 F316L flange is considered resistant to potable water. The
astm A182 Gr F316L is displays corrosion resistance in potable
water, which can cantainup to about 1000 mg/L chlorides at ambient
temperatures & gets reduced further to about 500 mg/L at 60 °C.
Flange astm a182 f316l is usually regarded as the standard “marine
grade stainless steel”.But the astm A182 grade F316L is not
resistant to warm sea water. In many marine environments 316l ss
flanges material does tend to exhibit surface corrosion. This
surface corrosion usually visible as brown staining, which is
especially associated with crevices and rough surface finish.
316L ss flanges exhibit good oxidation resistance in intermittent
applications up to a temperature of 870 °C and in continuous
service to 925 °C. Continuous use of flange astm A182 f316l between
the temperature range of 425 °C - 860 °C is not recommended if
subsequent aqueous corrosion resistance is important in any
application. Many 316L stainless steel flanges manufacturers note
that the alloy is more resistant to carbide precipitation and can
be used in the above that temperature range.

The ASTM A182 F316L SORF (Slip-On Raised Face) Flange is commonly used in various industries for piping systems. It is
particularly suitable for applications that require corrosion
resistance and high temperature strength. Some of the typical
industries where this flange is utilized include oil and gas,
chemical, petrochemical, power generation, and water treatment. The
ASTM A182 F316L designation specifies the specific grade of
stainless steel used, which offers superior resistance to corrosion
and is suitable for use in environments with elevated temperatures
and corrosive substances.
