ASTM A193 Gr.347 UNS S34700 Bolts Nuts Washers
ASTM A193 Gr.347 UNS S34700 Bolts Nuts Washers
ASTM A193 Grade 347, also known as UNS S34700, is a stabilized austenitic stainless steel alloy with additions of columbium and tantalum, offering excellent resistance to intergranular corrosion and high-temperature oxidation.
This alloy is widely used for bolts, nuts, studs, and washers in applications where elevated temperatures and corrosive environments are prevalent.
- **Chemical Composition**:
- Chromium (Cr): 17.0-20.0%
- Nickel (Ni): 9.0-13.0%
- Columbium (Cb) + Tantalum (Ta): 10x(C) min
- Manganese (Mn): 2.0% max
- Silicon (Si): 1.0% max
- Carbon (C): 0.08% max
- Phosphorus (P): 0.045% max
- Sulfur (S): 0.030% max
- **Mechanical Properties**:
- Tensile Strength: ≥515 MPa
- Yield Strength (0.2% Offset): ≥205 MPa -
Elongation (% in 2 inches): ≥35%
- Hardness (Brinell): ≤201 HB.
- **Why Use ASTM A193 Grade 347 Studs and Bolts**:
1. **High Temperature Performance**: ASTM A193 Grade 347 studs and bolts offer exceptional strength and stability at elevated temperatures, making them suitable for applications in heat exchangers, furnace components, and aerospace industry.
2. **Corrosion Resistance**: With its stabilized microstructure, ASTM A193 Grade 347 provides excellent resistance to intergranular corrosion and oxidation in high-temperature environments, ensuring longevity and reliability in chemical processing, petrochemical, and power generation industries.
3. **Stability and Durability**: The combination of columbium and tantalum stabilization enhances the stability and durability of ASTM A193 Grade 347 studs and bolts, reducing the risk of sensitization and carbide precipitation, and ensuring long-term performance in critical applications.
