We can produce material to any of the following specifications to meet your exact architectural and durability 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, facade contractors, and developers 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 material 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 that high-end exterior cladding projects demand.

 

What Makes 430 Stainless Steel Plate Ideal for Exterior Cladding?

Exterior cladding demands materials that combine long-term weather resistance, modern aesthetics, low maintenance, and cost efficiency. 430 stainless steel plate for exterior cladding meets these needs exceptionally well in non-coastal and urban environments.

The most popular finishes for cladding are NO.4 satin and 2B industrial matte, both of which provide excellent resistance to fingerprinting and surface wear while delivering a contemporary look that complements glass, stone, and concrete. As a nickel-free 430 ferritic stainless steel, it offers good atmospheric corrosion resistance, superior thermal conductivity, and low thermal expansion — properties that minimize warping and distortion on sun-exposed facades.

Compared to 304 or 316, 430 stainless steel material reduces project costs by 30–50% while still delivering decades of reliable performance in typical exterior conditions.

Chemical Composition

Our 430 stainless steel plate for exterior cladding strictly conforms to the chemical limits of all listed standards:

Element

Content (wt%)

Carbon (C)

≤0.12

Chromium (Cr)

16.00–18.00

Manganese (Mn)

≤1.00

Silicon (Si)

≤1.00

Phosphorus (P)

≤0.040

Sulfur (S)

≤0.030

Nickel (Ni)

≤0.75

The high chromium content forms a robust passive layer that protects against urban pollution, rain, and temperature fluctuations.

 

Mechanical Properties

Typical mechanical properties in the annealed condition (standard for cladding plates):

Property

Minimum Value

Typical Range

Yield Strength (0.2% offset)

≥205 MPa

220 – 280 MPa

Tensile Strength

≥450 MPa

450 – 600 MPa

Elongation (50 mm gauge)

≥22%

25 – 35%

Hardness (Rockwell B)

≤89 HRB

80 – 88 HRB

These properties provide excellent formability for roll-forming, bending, and profiling of cladding panels while maintaining sufficient strength for wind loads and structural support.

For European or DIN-standard cladding projects, please see our EN10088 2 X6Cr17 stainless steel sheet and DIN 1.4016 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. Hot rolling is followed by cold rolling on precision mills for superior thickness uniformity. Annealing and pickling ensure a clean base, followed by final brushing or skin-passing to create the required finish. Every batch undergoes rigorous inspection and third-party certification (SGS, TUV, BV) for full traceability.

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

Key Advantages for Exterior Cladding Projects

  • Excellent atmospheric corrosion resistancein urban and rural environments
  • Low maintenance— NO.4 and 2B finishes resist staining and require only occasional cleaning
  • Aesthetic versatility— modern satin or matte look complements contemporary architecture
  • Cost-effective— genuine China Yongjin 430 BA/2B material offers premium appearance at lower cost than 304 or 316
  • Thermal stability— low expansion coefficient reduces warping on sun-exposed facades
  • Lightweight yet strong— ideal for curtain wall and cladding systems

 

Wide Range of Exterior Cladding Applications

430 stainless steel plate for exterior claddingis widely used in:

  • Building facades and curtain wall systems
  • Exterior wall panels and column covers
