310S stainless steel mirror plate is a high alloy stainless steel belonging to the 25Cr-20Ni series, with excellent high temperature oxidation resistance. After mirror polishing, the surface is both beautiful and functional. It still maintains high strength in high temperature environments (such as 1000-1200°C), and its oxidation resistance far exceeds that of ordinary stainless steel (such as 304/316L).
The surface roughness of the 310S stainless steel polished plate supplied by GNEE is Ra≤0.05μm (8K mirror surface), the reflectivity is ≥90%, the gloss is high, and it is easy to clean. It is suitable for making various furnace components, with a maximum temperature of 1200℃ and a continuous use temperature of 1150℃. It is used for furnace materials and materials for automobile purification devices.
