German alloy tool steel 35WCRV7 is a high-quality steel that is widely used in various industrial fields. It is a specially treated alloy steel containing 35% chromium and 7% tungsten, as well as a small amount of vanadium. The addition of these elements gives 35WCRV7 excellent hardness and wear resistance, as well as good corrosion resistance and toughness.
During the manufacturing process, 35WCRV7 needs to be melted and rolled at high temperatures to ensure that its internal structure is uniform and defect-free. The surface treatment of this steel is also very important, and processes such as shot peening or carburizing quenching are often required to improve its surface hardness and wear resistance.
Due to its excellent performance, German alloy tool steel 35WCRV7 is widely used in cutting tools, measuring tools, molds, bearings and other industrial products. In terms of cutting tools, it is used to make high-performance cutting tools such as milling cutters, drills, turning tools, etc., which can withstand high-intensity cutting loads and friction. In terms of gages, it is used in the manufacture of measuring tools and gauges with high accuracy and long-term stable measurement performance. In terms of molds, it is used to make various plastic molds, die-casting molds, etc., and is able to withstand high pressure and high temperature working environments. In terms of bearings, it is used to manufacture high-precision, high-speed bearings with long service life and low maintenance costs.
