(min. ±0.30 mm); D4: ±0.50% (min. ±0.10 mm) |
Standards for 310S Stainless Steel Tube
310S stainless steel tube production and quality control adhere to
multiple international and national standards to ensure consistency
and reliability. Common standards include:
- ASTM A312 (Standard Specification for Seamless, Welded, and Heavily
Cold Worked Austenitic Stainless Steel Pipes)
- ASTM A790 (Standard Specification for Welded Ferritic/Austenitic
(Duplex) Stainless Steel Pipe)
- ASME SA213 (Specification for Seamless Ferritic and Austenitic
Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes)
- ASME SA249 (Specification for Welded Austenitic Steel Boiler,
Superheater, and Heat-Exchanger Tubes)
- GB/T 14976 (Chinese National Standard for Stainless Steel Tubes for
Fluid Transport)
Similar Grades
310S stainless steel has equivalent or similar grades in different
regional standards, which are interchangeable in most applications:
| Region/Standard | Grade Designation | Notes |
|---|
| China | 0Cr25Ni20 | Corresponding domestic grade |
| USA | TP310S (ASTM/ASME) | Often referred to as SA213/TP310S |
| Common Name | 2520 | Named after its approximate Cr (25%) and Ni (20%) content |
Applications of 310S Stainless Steel Tube
Due to its exceptional high-temperature strength (up to 1000°C) and
oxidation resistance, 310S stainless steel tube is widely used in
the following fields:
- Petrochemical Industry: Furnace tubes, heat exchanger pipes, and
high-pressure steam pipelines.
- Power Generation: Superheater and reheater tubes in coal-fired and
gas-fired power plant boilers.
- Waste Incineration: Flue gas ducts and pipelines handling
high-temperature corrosive emissions.
- Food & Pharmaceutical: High-temperature sterilization equipment
pipelines (non-toxic and corrosion-resistant).
- Automotive: Exhaust systems for high-performance vehicles and
racing cars.
- Aerospace: Components in jet engine exhaust systems and
high-temperature structural parts.
Packaging of 310S Stainless Steel Tube
To prevent damage during transportation and storage, 310S stainless
steel tubes are packaged with strict protective measures:
- Individual Protection: Each tube is wrapped in a plastic bag to
prevent scratches and moisture.
- Bundle Packaging: Tubes are bundled into hexagonal or rectangular
bundles using steel straps or nylon ropes. The ends of the tubes
are covered with plastic caps to avoid deformation.
- Outer Covering: Bundles are wrapped in waterproof film or hessian
cloth to resist rain and dust.
- Containerization: For long-distance transport, tubes are packed in
wooden crates, steel frames, or containers.
- Labeling: Each package is labeled with product details (grade,
size, quantity, batch number, and manufacturer information) for
easy identification.
Summary
310S stainless steel tube is a premium material designed for
extreme environments, characterized by its high chromium and nickel
content, excellent high-temperature performance, and wide range of
applications across industries. Its compliance with international
standards, compatibility with similar grades, and robust packaging
ensure reliability in transportation and use. Whether in energy
production, chemical processing, or high-performance engineering,
310S remains a top choice for demanding high-temperature and
corrosive conditions.
