1. What is the difference between tungsten steel and high-speed steel? Different properties High speed steel (HSS) is a tool steel with high hardness, wear resistance, and heat resistance. Tungsten carbide (cemented carbide) has excellent characteristics such as high hardness, wear resistance, excellent strength, toughness, heat resistance, and corrosion resistance.
2. The high-speed steel makes up for the fatal shortcomings of carbon tool steel due to its good red hardness. High-speed steel is mainly used to manufacture complex thin-edged and impact-resistant metal cutting tools, and can also manufacture high-temperature bearings and cold extrusion dies, such as turning tools, drills, hob cutters, machine saw blades and high-demand molds.
3. Different characteristics High speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance. Tungsten steel (cemented carbide) has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. Different compositions High speed steel is a complex steel grade, and the carbon content is generally between 70 and 65%.
4. In addition to being made of tungsten steel, cutting tools can also be produced with high-speed steel. However, due to the different chemical composition and production methods of tungsten steel and high-speed steel, the quality of the prepared cutting tools is also slightly different.
5. The difference between high-speed steel and tungsten steel In addition to being made of tungsten steel, cutting tools can also be produced with high-speed steel materials. However, due to the different chemical composition and production methods of tungsten steel and high-speed steel, the quality of the prepared cutting tools is also slightly different.
1. Commonly used steel grades are W18Cr4V, W6Mo5Cr4V2, etc. Special purpose high-speed steel: including cobalt high-speed steel and super-hard high-speed steel (hardness HRC68 7, mainly used to manufacture cutting tools for difficult-to-machine metals (such as high-temperature alloys, titanium alloys and high-strength steels, etc.), commonly used steel grades are W12Cr4V5COW2MO9CR4VCO8, etc.
2. What symbols are used for tungsten steel, high-speed steel and cemented carbide Tungsten steel, also known as cemented carbide, is commonly known as "tungsten steel"; The common name of high-speed steel is "white steel". Tungsten steel refers to a sintered composite material composed of at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide and tantalum carbide are common components of tungsten steel.
3. Tungsten steel (cemented carbide) has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, especially its high hardness and wear resistance, even at a temperature of 500, it remains basically unchanged, and it still has a high hardness at 1000.
4. Note: "X" after the grade indicates fine-grained alloy, "C" indicates coarse-grained alloy, and no word is general granular alloy. 0 The difference between tungsten steel and cemented carbide Generally speaking, tungsten steel is smelted by adding tungsten raw materials to molten steel in the steelmaking process, also known as high-speed steel or tool steel, and its tungsten content is generally 15-25%.
5. High-speed steel is mainly used to manufacture complex thin-edged and impact-resistant metal cutting tools, and can also manufacture high-temperature bearings and cold extrusion dies, such as turning tools, drills, hob cutters, machine saw blades and high-demand molds.
6. Cemented carbide grade: YG3X density G cm 16-1 flexural strength not less than N cm 132 hardness not less than HRA: 9 Common uses: It is suitable for high-speed finishing of cast iron, non-ferrous metals and alloy quenched steel, alloy steel, small cutting sections.
