Introduction to ASTM A182 F9 Material
ASTM A182 F9 is a specification that covers forged or rolled alloy steel flanges, fittings, valves, and parts for high-temperature service. This material, known for its exceptional strength and resistance to high temperatures, is particularly suited for demanding applications in industries such as oil and gas, petrochemical, and power generation.
Solution Treatment
Chemical Composition and Properties
ASTM A182 F9 material, with the UNS designation K90941, contains a notable composition of 9% chromium, which enhances its corrosion resistance and mechanical properties. The specified chemical composition includes:
| Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Silicon (Si) | Chromium (Cr) | Molybdenum (Mo) |
| ≤ 0.15% | 0.30 – 0.60% | ≤ 0.030% | ≤ 0.030% | 0.50 – 1.00% | 8.0 – 10.0% | 0.90 – 1.10% |
The heat treatment processes specified for ASTM A182 F9 include annealing at a temperature of ≥ 955 °C followed by furnace cooling, and normalizing (≥ 955 °C, air cooling) with subsequent tempering (≥ 675 °C).
Mechanical Properties
The mechanical properties of ASTM A182 F9 are critical for ensuring performance in high-stress applications. The requirements are as follows:
Tensile Strength: ≥ 585 MPa，Yield Strength: ≥ 380 MPa，Elongation: 20%，Reduction of Area: 40%，Hardness: HB 179 – 217
These specifications ensure that the material can withstand the rigors of high-temperature environments while maintaining integrity and performance.
