从China供应商批发进口403 Stainless Steel — FOB条款

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.

China Economic Steel Group (guangdong) operates from Guanglong Industrial Zone in Chencun Town, Shunde District, Foshan City, Guangdong Province. The supplier specializes in stainless steel products, including 403 grade materials, and serves industrial buyers in sectors such as thermal power, petrochemicals, and general engineering. The company’s profile indicates a focus on bulk supply for applications requiring cost-effective, heat-treatable alloys.

As a harbor-tier supplier, China Economic Steel Group (guangdong) aligns with international standards for stainless steel production, including ASTM and EN specifications. The company’s address and operational base in Guangdong Province position it as a regional hub for stainless steel distribution. Buyers should note that the supplier’s response rate and average response hours are currently unavailable, which may require direct outreach for trade terms or technical clarifications.
