High-alumina sintering plates (corundum-mullite sintering plates) are specially designed for sintering MIM stainless steel parts and are applicable to continuous furnaces and vacuum furnaces. The effective porosity reduces energy storage, and the high-purity inert composition prevents chemical reactions such as carburization, decarburization and chromium depletion during the sintering of parts, demonstrating excellent performance.
Our high-alumina sintering (corundum-mullite sintering plate) exhibits excellent sintering performance when used in continuous furnaces and vacuum furnaces for sintering MIM stainless steel parts. The effective porosity of the sintering plate ensures a very low energy storage capacity, while the high-purity and inert chemical composition prevents chemical reactions such as carburization, decarburization, and chromium depletion during the sintering process of MIM stainless steel parts.
