Material Characteristics
Corrosion Resistance: Maintains surface stability in chloride environments and acidic media, with a chromium oxide passivation film providing a barrier to penetration.
Mechanical Strength: Typical yield strength ranges from 205 MPa to 550 MPa (depending on grade and process).
Temperature Compatibility: Continuous operating temperature range of -196°C to 800°C (depending on the specific steel grade).
Surface Treatment: Polishing, sandblasting, or pickling are available, with surface roughness Ra values up to 0.4 μm.
Structural Parameters
Dimension Range: OD 6mm-2000mm, wall thickness 0.5mm-50mm.
Length Options: Fixed lengths from 6000mm to 12000mm, custom cutting available.
Roundness Tolerance: No more than 80% of OD tolerance.
Straightness: Deviation ≤1.5mm per meter.
Process Standards: Complies with international standards such as ASTM A312/A269, EN 10217-7, and GB/T 12771, and is equipped with a material traceability system and third-party inspection reports.
Application Areas
Chemical pipeline networks, food processing equipment, building water supply and drainage systems, medical gas pipelines, automotive exhaust systems, and other industrial scenarios.
