High-speed steel is a tool steel with high hardness, high wear resistance and heat resistance. Its high temperature resistance is better than that of carbon steel and alloy steel, so it is widely used in cutting, impact and mold making.
S18-1-2-10 is a standard high speed steel grade that is mainly composed of the following components:
0.85-0.95% carbon (c).
3.75-4.50% molybdenum (Mo).
3.80-4.40% chromium (CR).
1.00-1.40% cobalt (CO).
1.35-1.85% molybdenum(v).
0.25-0.45% silicon (Si).
The addition of these components gives the S18-1-2-10 excellent machinability and wear resistance. The high carbon content allows it to maintain a high hardness, while the high molybdenum and cobalt content improves the heat and wear resistance of the tool. The addition of molybdenum and chromium can also improve the corrosion resistance of the tool and extend its service life.
In addition to the composition, the S18-1-2-10 has the following parameter data:
Hardness: 60-62 HRC
Density: 790 g/cm³
Thermal conductivity: 24 W (m·k).
Coefficient of thermal expansion: 108 µm/(m·k)
Tensile strength: 1850-2100 MPa
Compressive strength: 2000-2300 MPa
These parametric data reflect the physical and mechanical properties of S18-1-2-10, which further proves its wide application in cutting tool and mold making.
In practical applications, S18-1-2-10 is suitable for cutting materials with high hardness and high wear resistance, such as stainless steel, heat-resistant alloys and titanium alloys. It can be used to manufacture cutting tools, grater tools, dies and punches, etc., and plays an important role in automotive manufacturing, aerospace and mold processing.
To sum up, S18-1-2-10 is an excellent tool steel with high hardness, wear resistance, and heat resistance. Its composition and parameter data make it widely used in the field of cutting and mold making. By fully understanding the S18-1-2-10, we can make better use of its performance advantages and improve the cutting efficiency and service life of the tool.
