Chemical composition and mechanical properties of A182 F60 flange forgings
ASTM A182 is a standard specification for forged or rolled alloy steel pipe flanges, forged fittings, valves, and parts for high-temperature service. One of the commonly used grades under this specification is F60, classified as a ferritic-austenitic stainless steel with UNS designation S32205.
Chemical Composition of A182 F60
The chemical composition of F60 grade is carefully balanced to offer high resistance to corrosion and strength. The composition includes:
Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Silicon (Si) | Chromium (Cr) | Nickel (Ni) | Molybdenum (Mo) | Nitrogen (N) |
≤0.030% | ≤2.00% | ≤0.030% | ≤0.020% | ≤1.00% | 22.0-23.0% | 4.5-6.5% | 3.0-3.5% | 0.14-0.20% |
This composition makes A182 F60 ideal for applications in aggressive environments, providing a balance of high corrosion resistance and mechanical strength.
Heat Treatment
The heat treatment process for A182 F60 is crucial to enhancing its mechanical properties. The material undergoes solution annealing at a temperature of ≥1020°C, followed by quenching in a liquid medium. It is then cooled to below 260°C to ensure proper mechanical performance and structure stability.
Mechanical Properties
The mechanical properties of A182 F60 flanges reflect their suitability for high-temperature and high-pressure environments:
Tensile Strength: ≥655 MPa
Yield Strength: ≥450 MPa
Elongation: ≥25%
Reduction of Area: ≥45%
These mechanical characteristics ensure that A182 F60 flanges maintain their structural integrity under extreme conditions, making them reliable for demanding industrial applications such as chemical processing, oil and gas, and power generation.Haihao Group has been engaged in the field of flange forging production for more than 40 years and has rich experience in project coordination.
