The 4Cr5MoSiV steel is suitable for aluminum alloy die-casting molds, tools, and mandrels used in hot extrusion and perforation, hammer forging dies, press forging dies, high-speed precision forging dies and plastic press dies, etc.
This hot work die steel is used as structural parts of aircraft, rockets, etc., with a working temperature of 400℃～500℃
The performance and service life of 4Cr5MoSiV steel are higher than that of 3Cr2W8V steel.
Focus on manufacturing special steel cast and forged
components for more than 25 years.
