Product Overview
Our Stainless Steel Strip (also known as stainless steel coil, stainless steel band, or stainless steel foil) is manufactured from premium stainless steel through hot rolling, cold rolling, การหลอม, and pickling processes. With excellent corrosion resistance, high strength, precise thickness tolerance, and various surface finishes, stainless strips are widely used in automotive, อิเล็กทรอนิกส์, เครื่องครัว, การก่อสร้าง, อุปกรณ์การแพทย์, and general manufacturing. We supply a comprehensive range of stainless steel strips in 304, 304ล, 316, 316ล, 321, 410, 420, 430, และ 201 grades, with custom widths, thicknesses, and surface finishes available.

Quality Control & Testing
Every batch of stainless steel strips undergoes rigorous quality control:
Raw Material: Chemical composition analysis (spectrometer), PMI testing, heat number verification
Process Control: In-line thickness monitoring (gamma ray/X-ray gauge), surface inspection, tension control, annealing temperature monitoring
Finished Product: Thickness measurement (micrometer), width measurement, coil weight verification, surface finish inspection, hardness test (Rockwell/Vickers), tensile test (ความแข็งแรงของผลผลิต, แรงดึง, elongation), cupping test (formability), salt spray test (ความต้านทานการกัดกร่อน)
Documentation: Mill Test Certificate (MTC) per EN 10204 3.1, material traceability, conformity certificate
