Material Description

347H stainless steel is an austenitic stainless steel that provides excellent intergranular corrosion resistance and high temperature strength through the addition of niobium (Nb) stabilizing element. Widely used in chemical, petroleum, electric power and other industries under high temperature environments.

Chemical Composition (Typical Values)

Carbon (C): 0.04-0.10%
Silicon (Si): ≤1.00%
Manganese (Mn): ≤2.00%
Phosphorus (P): ≤0.045%
Sulfur (S): ≤0.030%
Chromium (Cr): 17.0-19.0%
Nickel (Ni): 9.0-13.0%
Niobium (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 Range

Diameter range: typically 5mm to 300mm (customizable). Standard lengths: 3000mm or 6000mm, with custom lengths available per customer requirements.

International Standards

ASTM A479/A479M: Standard for high temperature stainless steel bars
ASTM A276: Standard for stainless steel bars and profiles
EN 10088-3: European standard for stainless steel
GB/T 1220: China stainless steel bar standard

Key Features

Intergranular corrosion resistance: Niobium addition prevents chromium carbide precipitation
High temperature strength: Maintains mechanical strength and oxidation resistance in high temperature environments
Good weldability: Suitable for various welding processes with stable post-weld performance
Oxidation resistance: Excellent performance in high temperature oxidation environments

Advantages

Excellent high temperature performance: Suitable for environments up to 800°C
Strong corrosion resistance: Good performance in acidic and alkaline media
Long service life: Long-term stability in harsh conditions reduces maintenance costs
Wide applicability: Meets requirements of complex working conditions across various industrial fields

International Grade Equivalents

United States	UNS S34709
Europe	1.4961 (EN)
Germany	X6CrNiNb18-10 (Werkstoff Nr.)
Japan	SUS347H (JIS)
China	0Cr18Ni11Nb (GB/T 1220)

Applications

347H stainless steel bars are widely used in the following industrial sectors:

Chemical industry: Reactors, heat exchangers, pipeline systems
Oil and gas: Downhole tools, valves, pump components
Power generation: Boiler components, superheaters, heat exchangers
Aerospace: High-temperature components, engine parts
