ASTM A182 F316L Forged Disc SS316 Forged Ring
We are a professional manufacturer of ASTM A182 F316L Forged Disc SS316 Forged Ring in China.
What is Forged Disc?
A forged disc is a solid, circular metal component produced through the forging process, which enhances its strength and durability.
The forging process is used to create large steel discs for use in industrial equipment, valves and other high-pressure components for the oil, gas and petrochemical industries.
A182 F316L Forged Disc
A forged disc made from ASTM A182 F316L is a corrosion-resistant, high-strength component widely used in industries such as oil & gas, chemical processing, marine, and food processing.

The Steel Disc Forging Process
Steel disc forging is a manufacturing process where a solid steel disc is produced through the application of heat and pressure, refining the grain structure and improving strength. The process typically includes the following steps:
1. Material Selection
- Choose the appropriate steel grade (e.g., carbon steel, alloy steel, stainless steel) based on the application.
- Common grades: A105, 4140, 304,316L, 17-4PH, etc.
2. Pre-Heating the Steel
- The steel billet or ingot is heated in a furnace to 1,100–1,250°C (2,000–2,300°F) to make it malleable.
- Controlled heating prevents defects such as cracks or uneven grain structure.
3. Forging the Disc
- The heated steel is placed under a press or hammer to shape it into a disc.
- Common forging methods:
- Open-die forging (for large discs)
- Closed-die forging (for precision shapes)
- Rolled ring forging (for seamless ring-like discs)
4. Heat Treatment
- To enhance mechanical properties, discs undergo:
- Annealing (softening)
- Quenching & Tempering (strengthening)
- Normalizing (refining grain structure)
5 Trimming & Machining
-
- Excess material (flash) is removed.
- CNC machining or lathe operations are used for precision finishing, drilling, and contouring.
6. Inspection & Testing
- Ultrasonic testing (UT) and Magnetic Particle Inspection (MPI) ensure internal quality.
- Hardness, tensile, and impact tests verify mechanical properties.
What is Steel Disc Forging Used for?
Steel forged discs, also known as pancake forgings, create blind flanges for oil, gas and petrochemical pipeline applications. They are also used in the industrial equipment used in industries such as steel production, power generation and power transmission.
We manufacture custom disc forgings up to 110” OD from any material grade specified by the customer. The most common industry applications for disc forgings are blind flanges and forged tubesheets.
