Our hot-sale stainless steel strips and belts, available in 316L, 304L, and 317L grades, blend high quality with affordability, making them a top choice for diverse applications. Crafted using advanced cold-rolled techniques, they feature precise dimensions and exceptional flatness, ensuring consistent performance in industrial, automotive, and food-grade projects. The 2B surface finish delivers a smooth, clean appearance, ideal for both functional and aesthetic needs. These low-carbon grades (304L, 316L, 317L) offer enhanced corrosion resistance, particularly in high-temperature or chemical-rich environments, while maintaining strong tensile strength. With competitive pricing without compromising on quality, these strips and belts balance durability, versatility, and cost-effectiveness, catering to projects requiring reliable, long-lasting stainless steel solutions.
The cold-rolling process (vs. hot-rolling) is critical to the product’s quality, delivering unmatched dimensional accuracy and structural stability:
Ultra-Tight Dimensional Tolerance: Cold rolling compresses the steel at room temperature, ensuring thickness tolerance as low as ±0.01mm (for 0.1-2mm thick strips) and width tolerance ≤±0.1mm. This precision avoids gaps or misfits in automated assembly (e.g., electronic component stamping, belt-driven machinery).
Refined Grain Structure: The process refines the steel’s internal grains, enhancing mechanical properties:
Higher tensile strength (304L: ≥485 MPa; 316L: ≥485 MPa) and yield strength (304L: ≥170 MPa) compared to hot-rolled strips.
Improved surface smoothness (preparing the base for 2B finish) and reduced internal defects (e.g., inclusions, voids)—critical for high-reliability applications (e.g., medical device parts).
Consistent Flatness: Cold-rolled strips have minimal warping (flatness error ≤1mm/m), ensuring they lay flat during installation or processing (e.g., conveyor belts, decorative panels) without needing secondary straightening.
2B Surface Finish: Balance of Aesthetics & Functionality
2B is the most widely used surface finish for stainless steel strips, achieved via cold rolling + bright annealing + skin passing—striking a perfect balance between appearance and practicality:
Smooth, Matte-Bright Appearance: Surface roughness (Ra) ranges from 0.1-0.8 μm, presenting a uniform, low-gloss finish that hides minor fingerprints or scratches. It meets both functional (e.g., industrial belts) and semi-decorative (e.g., appliance trim) needs without requiring expensive polishing.
Clean, Oxide-Free Surface: Bright annealing in a protective atmosphere (nitrogen/hydrogen) removes surface oxides, creating a dense, inert surface that:
Resists dirt and oil accumulation (easy to clean with mild detergent).
Meets hygiene standards (e.g., FDA, GMP) for food/medical contact (e.g., food conveyor belts, medical instrument casings).
Good Coating Adhesion: The slightly textured (non-mirror) surface provides ideal bonding for secondary treatments (e.g., painting, powder coating, plating) if additional corrosion protection or color customization is needed.
