SKD61 hot-work tool steel powder
SKD61 is equivalent to H13, a hot-work mold steel conforming to the JIS standard. TIJO employs an atmospheric atomization process to produce pre-alloyed powders, which are widely used in molds operating under high-temperature conditions, such as die-casting dies and hot-forging dies.
