Phosphorus (P): ≤0.045%
Sulfur (S): ≤0.030%
Chromium (Cr): 17.0-19.0%
Nickel (Ni): 9.0-13.0%
Nb (Nb): 10×C% ~ 1.10%
Mechanical properties (room temperature) :
Tensile strength: ≥515 MPa
Yield strength: ≥205 MPa
Elongation: ≥35%
Hardness: ≤192 HB
Physical properties:
Density: 7.98 g/cm³
Melting point: 1398-1427°C
Coefficient of thermal expansion: 16.6μm /m·°C (20-100°C)
Thermal conductivity: 16.3W /m·K (100°C)
Specification of 347H Stainless Steel Bar
Diameter range: usually 5mm to 300mm (can be customized)
Length: The standard length is 3000mm or 6000mm, and can also be customized according to customer requirements.
Standard of 347H Stainless Steel Bar 347H stainless steel rods are manufactured and inspected in accordance with the following international standards:
ASTM A479/A479M: Standard for high temperature Stainless Steel bars
ASTM A276: Standard for Stainless Steel bars and profiles
