Testermeter-TCB05-Stainless Steel-304 Thickness Calibration Block
Product Introduction
304 Stainless Steel Thickness Calibration Block is specifically designed for industrial non-destructive testing. It enables rapid calibration and performance verification of thickness measurement equipment through a high-precision stepped structure. Its core advantages include: Material Advantage: Made of food-grade 304 stainless steel with a density of 7.93g/cm³, it has strong oxidation resistance and can be used for a long time in high-temperature, humid or corrosive environments. Precision Manufacturing: The thickness tolerance of each step is controlled within ±0.01mm, and the surface roughness is ≤Ra 0.8μm, ensuring the reliability and repeatability of calibration data. |
Product Technical Features
High - precision Material and Structural Design Adopts 304 Stainless Steel material, which has excellent corrosion resistance and long - term stability, and is suitable for various industrial environments. The product features a one - piece stepped structure, containing 5 thickness gradients (5mm, 10mm, 15mm, 20mm, 25mm). The overall size is 100mm×20mm, and each step surface is 20mm×20mm, ensuring the accuracy and consistency of thickness calibration. Tolerance Control: The manufacturing precision reaches the level of ±0.01mm, meeting the strict requirements of international standards such as ASTM E317 for the calibration of ultrasonic testing equipment. Surface Treatment: The surface is precisely ground and polished, with a roughness ≤ Ra 0.8μm, and there are no obvious scratches or burrs, ensuring a close fit with the thickness - measuring probe and signal stability. Standardization and Compatibility Complies with ASTM E317 |
