403 stainless steel is a martensitic grade containing approximately 12% chromium and 0.01% carbon, supplied by China Economic Steel Group (guangdong) in forms such as pipe, coil, strip, plate, sheet, and tube. This grade conforms to ASTM A403 and is equivalent to the Chinese standard 1Cr12, offering a balance of strength and corrosion resistance suited for industrial environments. The material is magnetic and exhibits good thermal conductivity, making it a cost-effective alternative to austenitic grades for buyers sourcing bulk piping or pressure vessel components.
The composition of 403 stainless steel delivers moderate corrosion resistance in mild environments, though it is less resistant to pitting and crevice corrosion compared to 304 or 316 grades. It is heat-treatable, allowing it to achieve high hardness and strength levels, which is critical for applications like pump shafts, valve parts, and surgical instruments. Typical industry standards for this grade include ASTM A240 for plate and sheet, ASTM A276 for bars, and EN 10088-2 for corrosion-resistant steels. The material is also referenced in JIS G4304 and GB/T 3280 for hot-rolled and cold-rolled products.
This grade is widely used in thermal power, petrochemical, and general engineering sectors, particularly for boiler tubes, heat exchangers, and high-stress components in steam turbines. Buyers sourcing from China Economic Steel Group (guangdong) should confirm the specific form and dimensions required for their application, as the supplier offers multiple product variants. The material’s machinability is best in the annealed condition, while its hardened state may require specialized tooling. Lead times and packaging options are confirmed directly with the supplier.

Before ordering 403 stainless steel from China Economic Steel Group (guangdong), buyers should verify the grade’s suitability for their intended application, particularly its corrosion resistance in the operating environment. Confirm the specific form (pipe, coil, sheet, etc.) and dimensional tolerances, as these can vary between production batches. Request mill test certificates to validate the material’s compliance with ASTM A403 or equivalent standards.
Logistics details, including lead times, packaging, and Incoterms, should be clarified directly with the supplier. China Economic Steel Group (guangdong) is based in Guangdong Province, so buyers should account for regional shipping routes and potential port delays. For bulk orders, discuss whether the material will be delivered in coils, bundles, or custom packaging to avoid damage during transit. Payment terms, such as letters of credit or advance deposits, are also critical to confirm.
Quality checks should include visual inspection for surface defects, dimensional verification against the ordered specifications, and material testing for chromium and carbon content. For critical applications, buyers may request additional tests, such as hardness or tensile strength measurements, to ensure the material meets performance requirements. Documentation, including test reports and certificates of conformity, should accompany each shipment to guarantee traceability.
