347 stainless steel pipe shows good stability and durability when withstanding various external forces, and is suitable for use in various structural strength components. At the same time, due to its excellent corrosion resistance and weldability, it has good corrosion resistance in acids, alkalis, and salt liquids, and has good oxidation resistance and weldability in air below 800°C. .

Mechanical properties:

• High yield strength: Its yield strength is ≥205/MPa, which means that the material is not prone to deformation or fracture when subjected to external forces.
• High tensile strength: Its tensile strength is ≥520/MPa, which means that when the material is subjected to tensile force, it can resist large tensile force without breaking.
• High elongation: Its elongation is ≥35%, which means that the material can deform to a certain amount when subjected to external force and has good toughness.
• Moderate hardness: The numerical range of the hardness test is HBS≤187, HRB≤90, HV≤200. The hardness is moderate, and it has a certain strength, a certain plasticity and toughness
