347 Stainless steel
347 stainless steel is a niobium-stabilized austenitic grade designed for high-temperature service and resistance to intergranular corrosion, particularly in welded components. The alloy from China Economic Steel Group (guangdong) maintains mechanical integrity up to 870°C, making it a preferred choice for furnace parts, chemical processing equipment and exhaust systems in aerospace and industrial applications. Available forms include coil, strip, plate, sheets, tubes, pipe, flat and bar, all meeting international trade standards for flat-rolled and long products.
The niobium addition in 347 binds carbon to form stable carbides, preventing chromium depletion at grain boundaries and ensuring corrosion resistance even after welding. Typical industry use includes boiler superheater tubes, reheater tubes and steam piping in power generation, as well as heat exchangers and synthetic fibre production lines. The grade conforms to ASTM A240 for plate, sheet and strip, and ASTM A276 for bars, with equivalent EN 10088-2, EN 10095, JIS G4304, JIS G4305, GB/T 4237 and GB/T 3280 specifications for global compatibility.
Industrial buyers source 347 for its balance of oxidation resistance, strength and weldability in aggressive environments. Key sectors include petroleum, chemical, food and paper industries, where mill certification and HS classification under 7219 for flat-rolled or 7222 for bars are standard requirements. Confirm form availability, dimensional tolerances and surface finish with the supplier, as these vary by production run and end use.

Sourcing 347 Stainless Steel from China Economic Steel Group (guangdong) - China Import Guide
Before ordering, verify the exact form, dimensions and surface finish of 347 stainless steel to match your project’s specifications. Confirm whether the supplier provides mill test certificates and compliance with the relevant ASTM, EN or JIS standards for your industry. Request samples for destructive or non-destructive testing if the application demands rigorous quality control.
Logistics details to confirm include packaging type (e.g., wooden crates, bundled sheets), loading port in China and Incoterms such as FOB, CFR or CIF. Lead times for 347 can vary based on form and quantity, so agree on a realistic delivery schedule. Payment terms typically involve a deposit with the balance due before shipment, but these should be negotiated directly with the supplier.
Quality checks should cover dimensional accuracy, surface condition and mechanical properties as per the applicable standards. For high-temperature applications, ensure the material has been solution-annealed to relieve stresses from forming or welding. Documentation to request includes the mill certificate, heat number traceability and, where applicable, third-party inspection reports to validate conformity to specifications.
