• EN 10088-2 1.4016 / X6Cr17(Europe)
• DIN EN 1.4016(Germany)
• GB/T 3280 10Cr17 / 1Cr17(China)
• BS 1449 430S17(United Kingdom)
• ISO 4954 X6Cr17(International)

When manufacturers search for 430 stainless steel, AISI 430 stainless steel, SUS 430 stainless steel, Grade 430 stainless steel, SS 430 stainless steel, 430 ferritic stainless steel, cold rolled 430 stainless steel, 430 stainless steel coil, 430 stainless steel sheet, 430 stainless steel plate, or a reliable 430 stainless steel supplier, 430 stainless steel exporter, and 430 stainless steel factory, they often specifically request 430 2B stainless steel sheet anti-rust performance from top Chinese mill 430 stainless steel like Yongjin. As a direct Yongjin 430 agent, Gangsteel offers genuine China Yongjin 430 BA/2B with the brand premium and proven anti-rust properties that customers trust for cost-effective, long-lasting applications.

Why 430 2B Stainless Steel Sheet Offers Excellent Anti-Rust Performance

430 stainless steel sheet with 2B finish is a nickel-free ferritic grade containing 16–18% chromium. This high chromium content forms a stable, self-healing passive oxide layer on the surface that provides reliable protection against atmospheric corrosion, moisture, and mild industrial environments. The 2B cold-rolled finish further enhances anti-rust performance by creating a smooth, uniform matte surface that reduces crevices where moisture or contaminants can accumulate.

In urban, rural, and indoor conditions, 430 2B stainless steel sheet demonstrates excellent anti-rust resistance for many years without additional coatings. It is widely chosen when full marine or heavy chloride resistance is not required, delivering 30–50% cost savings compared to 304 while maintaining dependable rust prevention.

Chemical Composition That Delivers Anti-Rust Protection

The chemical composition of 430 2B stainless steel sheet is tightly controlled to maximize corrosion resistance:

The elevated chromium level is the primary reason for its strong anti-rust capability in non-aggressive atmospheres.

Mechanical Properties (Annealed Condition)

These properties ensure the sheet remains formable while retaining structural integrity in anti-rust applications.

For European or DIN-standard projects, please see our EN10088 2 X6Cr17 stainless steel sheet and DIN 1.4016 stainless steel sheet.

How the 2B Finish Enhances Anti-Rust Performance

The 2B cold-rolled finish (Ra 0.3–0.5 μm) provides a smooth yet slightly matte surface that:

• Minimizes crevices where rust can start
• Reduces adhesion of dust, grease, and airborne pollutants
• Allows easy cleaning and drying, preventing water spots that could lead to localized corrosion

Compared to mirror BA (which shows every mark) or brushed NO.4 (which has directional lines), the 2B finish strikes the best balance for long-term anti-rust reliability in everyday use.

For Chinese-standard projects, the identical material is also available under GB/T 10Cr17 1Cr17 stainless steel sheet.

Manufacturing Process at Gangsteel & Yongjin Mill

As a direct partner of Yongjin Stainless Steel (Yongjin Mill), we start with high-purity AOD-refined material. After precision cold rolling, the coils are annealed and pickled, followed by a controlled skin-pass rolling that creates the uniform 2B surface. Every batch undergoes rigorous corrosion testing and surface inspection to guarantee consistent anti-rust performance.

For Japanese-standard requirements, please see our JIS G4305 SUS 430 stainless steel sheet.

Available Specifications Optimized for Anti-Rust Applications

Gangsteel offers 430 2B stainless steel sheet in the following range:

• Thickness: 0.3 mm – 3.0 mm (popular anti-rust gauges: 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm)
• Width: 600 mm – 2000 mm
