    -Product Guidance-
    "RECRYTE firing containers, trays and Crucibles" have excellent thermal shock resistance and chemical corrosion resistance. These features as well as their thinness and light weight make these products suitable for applications such as fluorescent paint firing containers. Production is possible in various complex shapes.
    RS420, especially, has been widely used as a high-strength material.
