430 BA Bright Annealed Stainless Steel Properties

Gangsteel, as an authorized Yongjin 430 agent and direct exporter of Yongjin Stainless Steel (Yongjin Mill) — one of China’s top stainless steel producers from Zhejiang/Guangdong — supplies premium 430 BA bright annealed stainless steel with outstanding surface and physical properties. We can produce material to any of the following specifications to meet your exact requirements:

• JIS G4305 SUS430(Japan)
• ASTM A240 Type 430(USA)
• 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 buyers 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 BA bright annealed stainless steel 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 consistent bright-annealed surface properties that customers trust.

What Is 430 BA Bright Annealed Stainless Steel?

430 BA bright annealed stainless steelis cold-rolled ferritic stainless steel that undergoes a special bright annealing process in a protective hydrogen-nitrogen atmosphere. This eliminates the need for pickling and produces a highly reflective, mirror-like surface directly from the mill. The BA finish delivers exceptional visual appeal, high gloss, and low surface roughness while retaining all the inherent mechanical and physical properties of standard 430.

The result is a premium material ideal for visible applications where aesthetics, reflectivity, and cleanability are critical.

Chemical Composition

The chemical composition of 430 BA bright annealed stainless steel is tightly controlled and identical to all 430 grades:

Mechanical Properties (Annealed Condition)

Typical mechanical properties of 430 BA (same as standard 430):

Physical Properties

The high thermal conductivity and low thermal expansion of 430 make BA finish particularly suitable for applications requiring heat reflection or dimensional stability.

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

Surface Properties of 430 BA Bright Annealed Finish

The BA finish is what sets this variant apart:

• Surface Roughness (Ra): <0.10 μm (mirror-like)
• Gloss Level: 70–90% (highly reflective)
• Appearance: Brilliant, mirror-bright silver surface with no haze
• Reflectivity: Very high — excellent for heat and light reflection
• Cleanability: Outstanding — smooth surface wipes clean easily
• Fingerprint Resistance: Moderate (shows prints more than matte finishes)
• Scratch Resistance: Good when protected with film

The bright annealing process produces a clean, oxide-free surface that requires no additional polishing, saving time and cost in visible applications.

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 bright annealed in a controlled hydrogen-nitrogen atmosphere at 800–850 °C. This prevents oxidation and creates the signature mirror-like BA surface. Every batch is inspected with gloss meters and surface roughness testers to ensure uniform BA properties.

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

FAQ

What does BA stand for in 430 BA?Bright Annealed — a special annealing process in protective atmosphere.

Is 430 BA more expensive than 2B?Yes, typically 8–15% higher due to the specialized bright annealing process.

Does BA finish affect corrosion resistance?No — corrosion resistance is determined by the alloy chemistry, not the finish.

Can 430 BA be used for food contact?Yes, the smooth mirror surface is highly hygienic for many food-grade applications.

Is 430 BA magnetic?Yes — fully magnetic like all 430 grades.
