Several kinds of measuring tools and their properties and uses
9SiCr
Performance: 9SiCr is a commonly used low-alloy tool steel known for its excellent hardenability, toughness, and tempering stability. It is well-suited for graded quenching and austempering processes, resulting in minimal distortion during heat treatment. This makes it ideal for applications where dimensional accuracy is critical. Uses: It is widely used to manufacture complex-shaped tools that require high wear resistance and minimal deformation, especially at low cutting speeds. Common applications include drills, thread taps, dies, reamers, rolling wheels, gear cutters, machine molds, printing molds, cold rolls, calibration rollers, and slender components. Production Varieties: Available in hot-rolled, forged, and cold-drawn forms, as well as hot-rolled and cold-rolled steel wires, and bright silver wire. 8MnSi
Performance: This steel is an enhanced version of carbon tool steel T8, with increased silicon and manganese content. The addition of these elements improves the hardenability of the material, making it more suitable for various heat treatment processes. Uses: Typically used for woodworking tools such as chisels and saw blades, as well as inserts and other cutting components. Production Varieties: Includes hot-rolled, forged, and cold-drawn materials. CrO6
Performance: CrO6 is a low-alloy measuring tool steel containing a small amount of chromium. After heat treatment, it achieves high hardness and wear resistance. However, due to its high carbon content, it tends to form network carbides, which can reduce its performance, especially in large cross-sections. Tools with thin blades and large cross sections are more prone to brittleness. Uses: Ideal for manufacturing low-load cutting tools that require sharp edges, such as surgical instruments, razor blades, carving knives, trowels, scrapers, and wool shears. It is also used for both manual and motorized cutting tools. Production Varieties: Available in hot-rolled, forged, cold-drawn, and drawn steel wire forms, including bright silver wire. Cr2
Performance: Cr2 is a chrome-containing gauge steel, similar in composition to ball bearing steel GCrl5. By adding chromium to carbon tool steel T10, it enhances hardenability and hardness while maintaining stable dimensions during heat treatment. Uses: Widely used in the production of measuring tools like templates, gauges, block gauges, ring gauges, plug gauges, and sample holders. It is also suitable for cold dies, drawing dies, and low-speed cutting tools such as turning tools, inserts, reamers, cam pins, eccentrics, and cold rolls. Production Varieties: Available in hot-rolled, forged, and cold-drawn forms, as well as hot-rolled and pulled steel wires. 9Cr2
Performance: A cutting tool steel with a moderate chromium content, which improves hardenability. Even when quenched in oil, it can achieve high hardness. After proper heat treatment, it offers good wear resistance and a relatively uniform distribution of carbides. Uses: Suitable for cold tooling, stamping punches, dies, woodworking tools, and cold rolls. It is also used in the production of calender rolls. Production Varieties: Available in hot-rolled, forged, and cold-drawn forms, as well as hot-rolled and cold-rolled steel wires. Small to medium-sized modules can be supplied upon request. W
Performance: W is a cutting tool steel containing 0.80% to 1.20% tungsten by mass. It exhibits higher hardness and wear resistance than carbon tool steels, with lower thermal sensitivity and less distortion during heat treatment. It is less likely to crack when quenched in water and has better tempering stability. Due to its limited hardenability, it is typically used for small cross-sectional tools. Parts up to 10–15 mm thick can achieve uniform high hardness, with a hardness range of HRC 64–66. Uses: Used for manufacturing small cross-sectional tools such as twist drills, conical tools, and dies that do not require high cutting speeds or operate at low temperatures. Production Varieties: Available in hot-rolled, forged, cold-drawn, and drawn steel wire forms, including bright silver wire.
