ASTM A182 F316L Stainless Steel Flange Low Carbon Corrosion Resistant for Chemical Marine

ASTM A182 F316L flanges are austenitic stainless steel forged flanges manufactured according to ASTM A182/A182M standards, belonging to the American standard material standard for high-pressure forged flanges. This standard covers various grades including alloy materials, stainless steel, and duplex stainless steel, with F316L being one of the most widely used austenitic stainless steel grades.

As a low-carbon version of F316, F316L reduces the carbon content from 0.08% to below 0.030%. This design makes it less prone to sensitization after welding.

It is designed for environments in industries such as chemical engineering, marine engineering, and food processing that involve chloride ion corrosive media, require extensive welding, and demand resistance to intergranular corrosion.

Chemical Composition
Element	Content Range (%)	Metallurgical Function
C (Carbon)	≤ 0.030	Critical feature – extra-low carbon design prevents welding sensitization
Mn (Manganese)	≤ 2.00	Deoxidation; improves hardenability
P (Phosphorus)	≤ 0.045	Cold brittleness control
S (Sulfur)	≤ 0.030	Hot brittleness control
Si (Silicon)	≤ 1.00	Oxidation resistance improvement
Cr (Chromium)	16.0 – 18.0	Improves oxidation resistance and corrosion resistance
Ni (Nickel)	10.0 – 14.0	Stabilizes austenitic structure
Mo (Molybdenum)	2.0 – 3.0	Improves pitting resistance and crevice corrosion resistance
N (Nitrogen)	≤ 0.10	Solid solution strengthening

Core Difference Between F316 and F316L:
Comparison Item	F316	F316L
Carbon Content (C)	≤ 0.08%	≤ 0.030%
Welding Sensitization Risk	Present (Cr₂₃C₆ precipitates in HAZ)	None (extra-low carbon design)
Post-Weld Heat Treatment (PWHT)	Sometimes required	Rarely required
Yield Strength (min)	205 MPa	170 MPa
Tensile Strength (min)	515 MPa	485 MPa
Most Common Applications	Non-welded components or components requiring PWHT after welding	Default choice for welded piping systems

Mechanical Properties
Parameter	F316L Standard Requirement (Min.)	F316L Typical Value
Tensile Strength (Rm)	≥ 485 MPa (70 ksi)	485 – 777 MPa
Yield Strength (Rp0.2)	≥ 170 MPa (25 ksi)	170 – 889 MPa
Elongation (50 mm gage length)	≥ 30%	30 – 42%
Hardness (HBW)	≤ 217 HBW	≤ 217 HBW
Reduction of Area	—	≥ 22%
