Introduction to DIN EN X6Cr17 (1.4016)

The DIN EN X6Cr17 (1.4016) grade is a ferritic stainless steel specified under the DIN EN 10088 series, which harmonizes with European Norm (EN) standards for stainless steels. Specifically, EN 10088-2 outlines the technical delivery conditions for cold-rolled sheet, strip, and coils intended for general and corrosion-resisting applications. The "X6Cr17" nomenclature indicates a high-alloy steel ("X") with low carbon (approximately 0.06% implied by "6") and 17% chromium, while the numerical code 1.4016 is the material number assigned by the European Committee for Standardization (CEN). This grade's ferritic microstructure—body-centered cubic—confers magnetic properties, high thermal conductivity (around 25-27 W/m·K), and resistance to thermal expansion distortion, making it superior to austenitic counterparts in heat-related applications.

X6Cr17 excels in environments where oxidation resistance is crucial, withstanding temperatures up to 800-850°C in intermittent service without significant scaling. Its low carbon content minimizes sensitization during welding, reducing intergranular corrosion risks. Unlike martensitic steels, it does not harden excessively upon cooling, maintaining ductility for easy fabrication. Gangsteel's production adheres strictly to DIN EN tolerances, incorporating vacuum melting for purity and multi-stage cold rolling for uniform thickness. This results in coils that are ideal for stamping, deep drawing, and polishing, with applications spanning from automotive components to household goods. The material's eco-friendly profile—being fully recyclable and free of expensive nickel—aligns with sustainable manufacturing trends, further enhanced by China's efficient production ecosystem.

Chemical Composition and Mechanical Properties

Gangsteel ensures that our DIN EN X6Cr17 (1.4016) coils meet or surpass the specified limits through precise alloying and testing.

Chemical Composition

As per EN 10088-2, the composition is tightly controlled to balance corrosion resistance and weldability:

Chromium forms the core of its protective properties, while low phosphorus and sulfur enhance polishability and reduce pitting risks. Silicon aids in high-temperature stability, and minimal nitrogen prevents nitride formation. Gangsteel's batches are analyzed via optical emission spectrometry for consistency.

Mechanical Properties

Tested in accordance with EN ISO 6892-1, the annealed condition yields:

Density is approximately 7.7 g/cm³, with a melting range of 1425-1510°C. These properties support excellent cold workability, with bend radii as low as 1t (thickness) without cracking. Fatigue endurance is strong under cyclic loading, and cryogenic toughness remains viable down to -100°C.

Available Specifications and Finishes

Gangsteel's DIN EN X6Cr17 (1.4016) cold-rolled coils are versatile in dimensions and finishes to accommodate diverse requirements.

Gangsteel's Type 430 BA coils are available in thicknesses from 0.25 mm to 3.0 mm, widths up to 1500 mm, and coil weights tailored to customer needs. Standard specifications include coil IDs of 508/610 mm, ODs up to 2000 mm, and weights from 5-20 tons. Tolerances follow EN ISO 9445: thickness ±0.02-0.04 mm for thin gauges, width ±0.3 mm, camber ≤3 mm/m, and flatness ≤6 mm/m. Custom options encompass precision slitting (minimum 10 mm width), edge trimming (mill, slit, or rounded), and leveling for sheets up to 6000 mm long.

Surface Finishes

We provide a range of finishes compliant with EN 10088-2:

• 2D/2B: Annealed and pickled for a dull, smooth surface (Ra 0.3-0.6 μm), suited for functional parts.
• BA (Bright Annealed): Processed in inert gas for high gloss (Ra <0.1 μm, reflectivity >80%), ideal for decorative elements.
• No.4 (Satin): Brushed with 180-240 grit for fingerprint-resistant aesthetics.
• HL/Embossed: Custom patterns for anti-slip or visual effects.
• Protective Coatings: PVC/PE films or paper interleaving to prevent damage during transit.

Surface quality is verified through visual and laser inspection, ensuring compliance with Class A standards.

Manufacturing Process at Gangsteel

Gangsteel's process for X6Cr17 coils integrates cutting-edge technology for superior quality. Raw materials—high-purity scrap and ferroalloys—are melted in EAF or AOD refiners to achieve precise composition, with vacuum degassing for impurity removal. Hot rolling at 1100-1200°C produces black coils, followed by annealing at 800-900°C and pickling in acid baths to eliminate scale.

Cold rolling on reversible or tandem mills reduces thickness by 50-80% per pass, with intermediate annealing to restore ductility. Bright annealing in bell or continuous furnaces under hydrogen atmosphere yields the BA finish, preventing oxidation. Final skin-passing calibrates thickness and enhances surface. Quality assurance involves non-destructive testing (eddy current, ultrasonic), mechanical sampling, and certification by independent bodies like Lloyd's Register. This end-to-end control minimizes defects, achieving yields over 95%.

Equivalent Materials

DIN EN X6Cr17 (1.4016) aligns with numerous international grades, enabling global interchangeability based on similar chemistry and properties.

Equivalents like ASTM 430 share ≥220 MPa yield and 20% elongation, but verify for specific tolerances—e.g., DIN EN may require stricter flatness than GB. Gangsteel offers multi-standard certified coils for seamless substitution.
