1. What are the high-temperature resistant steels?
1. Martensitic hardening steelMartensitic hardening steel is a steel with high strength and high hardness, which can maintain stable hardness and strength under high temperature conditions. Its main advantages include high wear resistance, high strength, high impact resistance, and high corrosion resistance.
Therefore, it has a wide range of applications in automobile manufacturing, machinery manufacturing, cutting and other fields.
2. Tungsten carbide steel is also a common high-temperature resistant steel, and its alloying elements are mainly carbon and tungsten. It also has high hardness and wear resistance at high temperatures. An important feature of tungsten carbide steel is that it is resistant to high-temperature deformation, especially suitable for high-temperature, high-pressure, and high-load application environments.
3. Maraging heat-resistant steel - this kind of steel has a chromium content of 7~13%, and has high high temperature strength and water vapor corrosion resistance below 650 °C, and its disadvantage is that it is poor in weldability, such steel grades are: 1Cr11MoV, 1Cr12WMoV, 4Cr10Si2Mo, etc.
2. What are the common high-temperature resistant materials?
1. Common high-temperature resistant materials are: nickel-based alloys, ceramic materials, and brown corundum. In addition, granite, marble, gypsum, silica, etc., are more common high-temperature resistant materials, and they are also widely used.
2. Metal materialsMetal materials are one of the more common high-temperature resistant materials. At high temperatures, metal materials exhibit excellent mechanical, thermal, and creep properties. Common metal high-temperature materials include nickel-based alloys, tungsten, molybdenum, etc.
3. Ceramic, magnesium and aluminum compounds, mica, corundum, silicon, graphite, titanium alloy, diamond, tungsten, silicon dioxide, silicon carbide, carbon, copper oxide, ferric oxide, iron powder, manganese dioxide, etc., among which ceramics are more familiar to us with high-temperature resistant materials. And these high-temperature materials don't just have the properties of high temperatures.
4. High temperature resistant materials include: molybdenum, tantalum, niobium, vanadium, chromium, titanium, zirconium, nitride, phosphide, sulfide, etc. High-temperature resistant materials (refractories) generally refer to inorganic materials that can withstand temperatures above 1580°C. They are the building materials used in the construction of kilns, combustion chambers, and other objects that need to withstand high temperatures.
5. High-temperature resistant materials include: tantalum carbide hafnium alloy, graphite, diamond, tungsten, zirconium diboride, rhenium, silicon carbide, titanium diboride, titanium carbide, and osmium. Tantalum and hafnium carbide alloyTantalum and hafnium carbide alloy actually refers to five carbide and four tantalum hafnium compounds, which are substances with higher melting points in compounds.
