Product Description: DG60DG60 non-magnetic steel, also known as DG60 non-magnetic hard alloy steel, is a type of high-hardness non-magnetic mold steel. This steel can be directly quenched after carburization, offering advantages such as high production efficiency, low cost, and minimal oxidation and decarburization. However, due to its high hardness, it has relatively poor toughness. The as-delivered hardness of DG60 is 55-60 HRC.DG60 non-magnetic steel has a high hardness of HRC 57-61.Q: What material is DG60? Performance introduction.A: DG60 non-magnetic steel. This steel maintains a stable austenitic structure under various conditions, with very low magnetic permeability, high hardness and strength, and relatively good wear resistance.Q: What is the difference between DG60 and imported HPM75?A: HPM75 and DG60 differ in hardness;Q: What is the as-delivered HRC hardness of DG60?A: As-delivered hardness is HRC 57-61;Q: What is the chemical composition of DG60?A: Reference: Ni 55, Cr 45, with the remainder being rare earth elements. Tested hardness ranges from 57 to 61, grain size is grade 5, bending strength is 716 kg, impact toughness is 1.05 KG-M, and magnetic permeability is 1.0001.Q: What is DG60 non-magnetic steel used for?A: DG60 is suitable for manufacturing non-magnetic molds, non-magnetic bearings, and other structural components that require no magnetic induction in strong magnetic fields.Q: Is DG60 the same as stainless steel 304?A: DG60 is a non-magnetic mold material, while 304 is a genuine stainless steel series;Q: What is the price of DG60?A: DG60 non-magnetic steel is divided into two types: raw material and processed material (after solution treatment). Some unscrupulous manufacturers use stainless steel as a substitute, leading many companies to purchase materials in two batches, increasing original costs.Q: What is the heat treatment method for DG60 non-magnetic steel?A: DG60 has already undergone hardness treatment upon delivery.DG60 is a high-hardness non-magnetic mold steel, also known as non-magnetic hard alloy steel; its as-delivered hardness is HRC 58-62. DG60 non-magnetic hard alloy and non-magnetic steel (7Mn15Cr2Al3V2WMo, hereinafter referred to as 7Mn15Cr2Al3V2WMo). Non-magnetic hard alloy offers good wear resistance but has a long production cycle and high mold processing costs, making it suitable for long-term products. 7Mn15 non-magnetic steel has lower wear resistance, a shorter mold manufacturing cycle, and lower costs, making it suitable for products with limited production volumes and short cycle requirements. The application range of DG60 non-magnetic steel is relatively narrow, and its heat treatment and processing工艺流程 as a mold are not widely understood.DG60 (1) Direct Quenching: Direct quenching after carburization offers high production efficiency, low cost, and minimal oxidation and decarburization. However, due to the high carburization temperature, austenite grains grow, resulting in coarse martensite and more retained austenite after quenching, leading to poorer wear resistance and toughness. It is only suitable for fine-grained steels and parts with low wear resistance or low load-bearing requirements.DG60 (2) Single Quenching: After slow cooling from carburization, the steel is reheated above the critical temperature, held, and then quenched. Compared to direct quenching, single quenching can refine the steel's structure to some extent. When high core structure requirements exist, the single quenching temperature is slightly above Ac3. For parts requiring high surface wear resistance and hardness but low load-bearing, the quenching temperature should be 30°C–50°C above Ac1 to refine surface grains while leaving the core structure largely unchanged, resulting in slightly lower performance.DG60 (3) Double Quenching: For parts requiring high mechanical properties or coarse-grained steels, double quenching should be used. The first quenching aims to improve the core structure, with a heating temperature 30°C–50°C above Ac3. The second quenching aims to refine the surface structure, obtaining fine martensite and uniformly distributed granular secondary carbides, with a heating temperature 30°C–50°C above Ac1. DG60 is a high-hardness non-magnetic mold steel, also known as non-magnetic hard alloy steel; its as-delivered hardness is HRC 58-62. Austenitic non-magnetic steels are divided into non-magnetic high-manganese structural steels and non-magnetic stainless steels. Non-magnetic high-manganese structural steels are mainly used in civil fields such as power, transportation, and construction, while non-magnetic stainless steels are primarily used in high-tech fields like national defense and military industries. This analysis covers the domestic and international development and research overview of Fe-Mn series, Fe-Mn-Cr series, and Fe-Mn-Al series non-magnetic high-manganese structural steels, as well as non-magnetic stainless steels. It proposes China's development strategy for creating reduced-resource high-manganese non-magnetic steels that save on metals like Ni, Mo, and Cr, and high-end non-magnetic stainless steels. This approach meets both the mechanical and non-magnetic performance needs of civil applications and the comprehensive performance requirements of national defense and military applications, such as good mechanical properties, weldability, and corrosion resistance.Zexin Metal DG60 Non-Magnetic Steel Grade, Metallographic Structure, Mechanical Properties, Compressive Strength, Yield Strength, Elongation, Reduction of Area, Aging Temperature, Solution Treatment Strength, Processing Tools, Heat Treatment, Chemical Composition, Standard Specific Gravity, Hardness, Density, Non-Magnetic Steel Processing Tools, Non-Magnetic Steel Drilling, Tapping, and other mold steel information, please consult Dongguan Zexin Metal Materials. more>

As a representative of intelligent guided tour solutions, the multi-channel wireless zoned interpretation system is transforming traditional guided tour models with its unique technological advantages, offering a brand-new service experience for various exhibition halls, museums, tourist attractions, and other venues.This system divides the exhibition hall into multiple independent interpretation zones through precise spatial partitioning technology. Each zone is equipped with dedicated audio devices that form an intelligent linkage with the central control system. Its core advantage lies in breaking the limitations of traditional guided tour equipment that requires wearing receiving terminals. Instead, it employs environmental audio coverage technology—when a guide provides commentary in a specific zone, the sound is broadcast in real-time through the speakers in that area. This design not only eliminates the hassle of visitors wearing devices but also realizes the innovative concept of a "zone-exclusive sound field," ensuring that sound is clearly transmitted only within the current activity area and avoiding interference between adjacent exhibition zones.The multi-channel wireless zoned interpretation system demonstrates strong environmental adaptability. The main unit adopts a modular design—compact yet powerful—and can be quickly deployed and installed according to the acoustic structure of different venues. The system supports unlimited expansion of the number of zones, allowing flexible configuration for everything from small corporate exhibition halls to large museum clusters. In practical applications, the system can simultaneously host multiple visitor groups, with each group conducting activities independently in different zones without mutual interference in the commentary content, significantly enhancing the venue's reception efficiency and service quality.The widespread application of zoned interpretation systems marks the transformation and upgrading of exhibition hall services from mechanization to intelligence. It retains the emotional warmth of human-guided tours while integrating the convenience enabled by technology, creating a more autonomous and comfortable visiting experience for audiences. At the same time, it provides venue managers with more efficient and precise operational tools. This win-win solution is redefining the service standards of modern exhibition halls. more>

Company: 深圳市宝安区松岗开创铜铝材料厂

Product Description: White copper bar is a nickel-zinc-copper alloy. White copper bars based on copper and nickel-zinc alloy with the addition of other elements such as lead, manganese, aluminum, etc., are correspondingly referred to as lead white copper bar, manganese white copper bar, aluminum white copper bar, etc. Copper-nickel-zinc alloys exhibit good corrosion resistance, moderate strength, high plasticity, and can be processed under hot and cold pressure conditions. They also possess excellent electrical properties, making them not only structural materials but also important high-resistance and thermocouple alloys.Common white copper bars mainly include four grades: B0.6, B5, B19, and B30. The most commonly used ones on the market are B12, B18, and C7941. The American standard includes a wider range of grade series. White copper bar is a continuous solid solution formed by Cu and Ni, with a face-centered cubic lattice, as shown in Figure 1-18. When the temperature is below 322 degrees, the copper-nickel phase diagram exhibits a relatively broad composition-temperature region of metastable decomposition. Adding third elements such as Fe, Cr, Sn, Ti, Co, Si, Al, etc., to Cu-Ni alloys can alter the range and position of the metastable decomposition composition-temperature region, while also improving certain properties of the alloy.Common white copper bars have good cold and hot working properties. They can be easily processed into various shapes such as plates, strips, tubes, bars, profiles, and wires. They exhibit good weldability, allowing for soft and hard soldering, gas-shielded arc welding, and resistance welding. Their machinability is 20% that of free-cutting brass HPb63-3.Common white copper bars offer good corrosion resistance, moderate strength, high plasticity, and the ability to undergo cold and hot pressure processing.
