SA182 F316L Forged Ring – A Corrosion-Resistant Austenitic Stainless Steel Forgings

Description

What Is SA182 F316L Forged Ring?

SA182 F316L forged ring is the one of the series austenitic stainless steel forging with low-carbon S31603 being the UNS number that identifies this material. Because of its improved corrosion resistance and weldability, F316L forged rings find extensive application as high-quality semi-finished products from which the next generation of the most demanding circular components working in corrosive and high-pressure environments is made.

Material Characteristics of SA182 F316L

An Ultra-Resistant Stainless Steel

The SA182 F316L benefits from an elevated content of chromium, nickel, and molybdenum, which makes it the material of choice for such applications as:

• Chloride environments
• Acids and chemical media
• Pitting and crevice corrosion

Compared with 304 stainless steel, 316L forged stainless steel has better resistance to corrosion when used in seawater and chemical processing applications.

The Low Carbon Advantage

With a carbon content of no more than 0.030%, SA182 F316L is able to significantly lower the occurrence of carbide precipitation in the area of the weld during the welding operation or if the material is exposed to high temperatures.

Some of the benefits are:

• Lower sensitivity to intergranular corrosion
• Improved weldability
• Higher structural stability at elevated temperatures

316L welding structures, therefore, are more long-lasting and trustworthy in the presence of any form of corrosion and in offshore environments.

Reliable Mechanical Properties

Typically the mechanical properties of the material in the solution-treated condition are:

• Tensile strength ≥ 70 KSI
• Yield strength ≥ 25 KSI
• Elongation ≥ 40%

Such mechanical properties are the reason why F316L forged rings would be capable of handling scenarios of high loads, vibration, and repeated industrial service stresses.

Why Forged Rings Instead of Rolled or Cast Parts?

SA182 316L forged rings cannot be considered end products. These are non-machined high-strength ring blanks of the semi-finished material that are destined to be further machined into the final ​‍​‌‍​‍‌​‍​‌‍​‍‌components.

Forging benefits:

• Refined grain structure
• Eliminated internal defects
• Higher fatigue strength
• Stable mechanical behavior under pressure

Common end-use products include:

• Flanges
• Bearing rings
• Gear rings
• Turbine rings
• Sealing rings

High-pressure pipe system components
