MH-35 tool steel is a common tool steel material with excellent mechanical properties and wear resistance. The following is a detailed introduction to MH-35 tool steel.
1.Material Composition:
MH-35 tool steel is mainly composed of carbon (C), molybdenum (Mo), cobalt (Co), vanadium (V), chromium (CR) and other elements. Its chemical composition is as follows:
Carbon (c): 090-1.05%
Molybdenum (Mo): 475-5.50%
Cobalt (Co): 325-3.75%
Vanadium (v): 175-2.25%
Chromium (cr): 300-3.50%
In addition, it also contains a small amount of silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements.
2.Mechanical Properties:
MH-35 tool steel has excellent mechanical properties, making it widely used in the field of tool and die making. Its main mechanical performance parameters are as follows:
Strength: MH-35 tool steel has high yield strength and tensile strength, which is able to provide enough strength to withstand the working load.
Toughness: Despite its high hardness, MH-35 tool steel is still quite tough, providing good impact toughness in some high-strength applications.
Fatigue resistance: MH-35 tool steel has excellent fatigue resistance, able to maintain stable performance under long-term use and repeated loads.
Abrasion resistance: MH-35 tool steel has excellent wear resistance and is able to withstand wear and grinding of the working surface.
3.Heat Treatment:
MH-35 tool steels are often heat treated to improve their mechanical properties and wear resistance. Common heat treatment methods include quenching, tempering, etc. Quenching improves hardness and wear resistance, while tempering increases toughness.
4.Applications:
Due to its excellent mechanical properties and wear resistance, MH-35 tool steel is widely used in the following fields:
Mold Manufacturing: MH-35 tool steel is commonly used in the manufacture of plastic molds, die-casting molds, injection molds, etc., which can provide enough hardness and wear resistance to meet the needs of molds.
Cold mold: MH-35 tool steel is suitable for cold work molds such as cold shear molds and shear molds, which can provide good strength and toughness.
Cutting tools: MH-35 tool steel can also be used to make cutting tools, such as drills, milling cutters, cutters, etc., which can maintain stable performance at high speed cutting and heavy loads.
Summary: MH-35 tool steel is a high-quality tool steel material with excellent mechanical properties and wear resistance. It is widely used in a variety of tool and die making fields to meet the requirements for high strength and wear resistance. At the same time, heat treatment can also further improve its performance and make it more suitable for different working conditions.
