430 NO.4 Stainless Steel Plate Scratch Resistance

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 NO.4 stainless steel plate with outstanding scratch resistance. We can produce material to any of the following specifications to meet your exact project 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 architects, hardware manufacturers, furniture makers, and contractors 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 NO.4 stainless steel plate from top Chinese mill 430 stainless steel like Yongjin for its superior visual scratch resistance. As a direct Yongjin 430 agent, Gangsteel offers genuine China Yongjin 430 BA/2B with the brand premium and consistent NO.4 brushed surface that effectively hides daily wear.

Why 430 NO.4 Stainless Steel Plate Has Excellent Scratch Resistance

The NO.4 finish on 430 stainless steel plate is created by mechanically brushing the annealed and pickled surface with 150–320 grit abrasives in a uniform directional pattern. This produces a fine satin texture (Ra 0.20–0.80 μm) that visually camouflages minor scratches, scuffs, and fingerprints far better than mirror-like BA or smooth 2B finishes.

Because the brushed lines break up light reflection and diffuse surface imperfections, light scratches blend into the texture and become almost invisible. This makes 430 NO.4 stainless steel plate the preferred choice for high-touch, high-traffic areas where appearance must remain pristine without frequent polishing or refinishing.

Chemical Composition

The chemical composition of 430 NO.4 stainless steel plate is identical to standard 430 and optimized for long-term durability:

The high chromium content forms a robust passive layer that works together with the NO.4 texture to deliver excellent anti-rust and scratch-hiding performance.

Mechanical Properties (Annealed Condition)

Typical mechanical properties of 430 NO.4 stainless steel plate (same across all finishes):

These properties ensure the plate remains formable for bending and fabrication while providing sufficient strength for architectural and hardware use.

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

Surface Properties Focused on Scratch Resistance

The directional brushed texture is the key to superior visual scratch resistance — minor marks blend into the satin lines instead of standing out.

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 cold rolling and annealing, the plates undergo multi-stage mechanical brushing with controlled 150–320 grit abrasives under precise pressure and speed. This creates the uniform directional NO.4 satin surface optimized for scratch hiding. Every batch is tested with gloss meters, roughness testers, and visual inspection to ensure consistent scratch-resistance performance.

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

Available Specifications Optimized for Scratch Resistance

Gangsteel offers 430 NO.4 stainless steel plate in the following range:

• Thickness: 0.5 mm – 3.0 mm (popular gauges: 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, 2.0 mm)
• Width: 600 mm – 2000 mm
• Length: Up to 6000 mm
• Tolerance: Thickness ±0.03 mm, width ±0.5 mm, flatness ≤8 mm/m

Protective PVC/PE film is standard to preserve the scratch-resistant surface during transport and fabrication.

FAQ

Does 430 NO.4 have better scratch resistance than BA?Yes — the brushed texture hides scratches far better than mirror BA.

Is 430 NO.4 more scratch-resistant than 304 NO.4?Visually similar; base alloy corrosion resistance differs, but scratch-hiding performance is comparable.

Can deep scratches be repaired on NO.4?Light scratches blend in; deeper ones can be refinished with fine abrasive pads following the grain.

Is 430 NO.4 suitable for high-traffic areas?Yes — the satin finish is designed exactly for high-touch, high-traffic environments.

Does the NO.4 finish affect corrosion resistance?No — corrosion resistance depends on the alloy, not the finish.
