Japan Sanyo QCM series cold work die steel

The QCM Series cold formed die steel from Yamagata Corporation in Japan offers a unique blend of properties and is ideal for use in a variety of industrial and consumer applications. This high-performance chromium-molybdenum-vanadium alloy is especially suited for hot-forming of intricate components required for high-precision tools and heavy-duty automotive parts. Extremely high fatigue strength and excellent wear resistance set it apart from other steel products. The combination of low ultimate tensile strength and high ductility make the QCM alloy the ideal choice for dynamic structural applications.

The QCM alloy has been designed to contain additional elements in its chemistry to increase the overall strength and durability of the alloy. Chromium, molybdenum and vanadium are combined as high-strength agents to improve strength and toughness. Additional elements such as titanium, boron, cobalt, silicon and manganese are present to provide further strength and heat resistance.

By adding these alloying elements, the QCM Series is able to ensure an exceptional level of performance in both static and dynamic loading situations. QCM alloy is suitable for applications involving rolling, forging and extrusion in the manufacture of complex parts with tight dimensional tolerances. It is also used to produce forgings and castings for components that require highly reliable strength and wear resistance in automotive, aerospace, synthetic and hardface engineering.

QCM alloy is known for its ability to withstand extreme temperatures and shock loads, making it an excellent choice for demanding applications such as high-pressure valves, power tools and wear parts. Its low thermal expansion coefficient means that even when heated up to high temperatures, it will not experience any significant dimensional changes.

The combination of high strength, excellent wear resistance and low thermal expansion make the QCM alloy an important material for the manufacture of precision die tools, heavy-duty components for the automotive industry, and other precision parts for general engineering. Its ability to hold tight dimensional tolerances and maintain its stability over a wide range of temperatures helps to create a reliable product that can be used in a variety of applications. The product’s high fatigue strength and resistance to abrasion and wear make it an ideal choice for industries that require parts that can withstand extreme conditions.

QCM is a series of cold working die steel produced by YANAGI of Japan. It is developed with domestic technology and manufacturing process, and integrates multiple international superior steel grades. It has superior performance, high strength and toughness, good hardenability, stable quenching and tempering performance, uniform hardness, good impact toughness and wear resistance, etc. It is mainly used in making cold working molds, such as punching dies, extrusion dies and thread-rolling dies.

QCM die steel has superior properties such as high original hardness, uniform hardness, strong wear resistance and impact toughness. After quenching and tempering, the internal organization is uniform, the hardness is high and uniform, and the toughness is excellent; the original hardness can reach HRC43-48, which can adapt to complex and medium and large mold shapes. In addition, the coefficient of thermal expansion is moderate, which can ensure the accuracy of the mold after heat treatment and the interchangeability of the mold.

QCM die steel has superior performance, excellent malleability, uniform hardness, no obvious quenching stress, and excellent corrosion resistance, which is more stable in the process of heat treatment. And with reasonable cost performance, it can fully meet the requirements of making all kinds of molds, even cold work die steel with high requirements. In addition, the steel can be produced in a wide range of sizes, such as plate, bar, tube, etc., suitable for different uses.
