310S/2520 High-temperature Resistant Stainless Steel Pipe

310S/2520 Extremely high temperature resistance, capable of long-term operation in environments of 1000~1200℃, with even higher short-term temperature resistance. It is a high-temperature specialized material that cannot be replaced by conventional stainless steel. High chromium and nickel content (25Cr+20Ni), it has extremely strong resistance to oxidation and sulfidation, and is not prone to peeling, flaking, or burning at high temperatures. It is not easily deformed or sags under high-temperature loads.

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
