321 NO.1 2B BA Cold Rolled Stainless Steel Strip represents a top-tier product in the stainless steel market, characterized by its excellent mechanical properties and aesthetic appeal. This strip is manufactured through a cold rolling process that enhances its strength and surface quality, making it suitable for demanding applications where both formability and resistance to high temperatures are crucial. The NO.1 finish provides a rough, scaled surface ideal for industrial uses, while the 2B finish offers a smooth, slightly reflective surface common in general applications, and the BA (Bright Annealed) finish delivers a mirror-like, highly reflective appearance perfect for decorative and精密 components. Key parameters include a thickness range from 0.1mm to 3.0mm, width options from 10mm to 1000mm, and standard lengths up to 2000mm, though custom dimensions are available. The material composition typically features chromium (17-19%), nickel (9-12%), and titanium (5xC min) for stabilization against carbide precipitation, ensuring enhanced weldability and intergranular corrosion resistance. Mechanical properties boast a tensile strength of 515 MPa minimum, yield strength of 205 MPa minimum, and elongation of 40% minimum, providing excellent ductility and toughness. Surface finishes adhere to international standards like ASTM A240, with the NO.1 finish having a dull, hot-rolled appearance, the 2B finish being cold-rolled, annealed, and pickled for a smooth matte look, and the BA finish achieved through bright annealing for a glossy surface. Applications span across heat exchangers, furnace parts, and exhaust systems, where its ability to withstand temperatures up to 900°C makes it indispensable. Available in various grades and certifications, including ASME and ISO, this strip ensures compliance with global quality benchmarks, offering reliability for critical industries.
