Anonymous users2024-02-14Generally, stainless steel has a high temperature resistance of 525 degrees, and carbon steel has a high temperature resistance of 350 degrees.
Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel according to its microstructure. In addition, according to the composition, it can be divided into chromium stainless steel, chromium-nickel stainless steel, and chromium-manganese-nitrogen stainless steel. There is also a special stainless steel for pressure vessels "GB24511 2009 Stainless steel plate and steel strip for pressure equipment".
Key features: 1. Solderability.
Different product uses have different requirements for welding performance. A type of tableware generally does not require welding performance, and even some pot and pan companies are included. But most products require raw materials with good welding performance, such as secondary tableware, thermos cups, steel pipes, water heaters, water dispensers, etc.
2. Corrosion resistance.
Most stainless steel products are required to have good corrosion resistance, such as Class I and II tableware, kitchenware, water heaters, water dispensers, etc. Some foreign merchants also carry out corrosion resistance tests on products: heat to boiling with NaCl aqueous solution, and then pour it out after a period of time.

Anonymous users2024-02-131. The heat-resistant temperature of steel is not the melting point, you must know that the heat-resistant temperature refers to the various performance indicators of steel at this temperature can meet the requirements of use, for example, the yield strength will be reduced in the case of heating. So now the temporary heat-resistant steel is 1000 degrees 2, graphite can withstand 1800 degrees of temperature, the melting point of graphite is 3850 50, the boiling point is 4250, 2000 does not soften. LZ--75LZ--65 High Alumina Brick Softening Point 1520,1500 Refractory 1790 Degrees SiC--85 Silicon Carbide Brick Softening Point 1600 Degrees I hope my answer can help you.

Anonymous users2024-02-12<>1. Metal materials with high temperature resistance of 1500 degrees, that is, metals with a melting point of more than 1500 are tungsten, rhenium, osmium, tantalum, niobium, iridium and other metals. Tungsten, a metallic element. Atomic number 74, atomic weight.
Steel gray or silvery-white, high hardness, high melting point, not eroded by air at room temperature; The main use is to manufacture filament and high-speed cutting alloy steel, superhard mold, and is also used in optical instruments and chemical instruments. China is the world's largest depositor of tungsten.
2. Rhenium is a chemical element with the symbol RE and the atomic order of 75. Rhenium is a silvery-white heavy metal that belongs to the 6th period transition metal in the periodic table. It is one of the rarest elements in the Earth's crust, with an average estimate of one part per billion.
At the same time, it is also one of the elements with the highest melting and boiling points. Rhenium is a by-product of the molybdenum and copper refining process.
3. Osmium is a member of the sixth periodic group of the periodic table and a member of the platinum group metals. The element symbol is os, atomic number 76, relative atomic mass. It is a heavy platinum group metal and is the densest metal known at present.
4. Tantalum ta, a metallic element, mainly exists in tantalite and symbiotes with niobium. Tantalum has moderate hardness and malleability, and can be drawn into thin foils. Its coefficient of thermal expansion is very small.
5. Niobium is a chemical element. The chemical symbol NB, atomic number 41, atomic weight, belongs to the periodic system B group. 1801 British C
Hatchett isolated an oxide of a new element from niobite and named it columbium. Niobium is an off-white metal with a melting point of 2468, a boiling point of 4742, and a density of grams of cubic centimeters.

Anonymous users2024-02-11We are happy to answer for you: What are the long-term 1500 high temperature resistant steels? Answer; Qinqin long-term 1500 high temperature resistant steel rebar channel steel steel plate ductile iron pipe I-beam heat resistant steel 2520 stainless steel can work for a long time at a high temperature of 1250, and will be deformed when working at a temperature of 1500.
2520 stainless steel is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance, because of the higher percentage of chromium and nickel, it has much better creep strength, can continue to work at high temperatures, and has good high temperature resistance. 2520 stainless steel flat bar, round bar, stainless steel plate, stainless steel rod, stainless steel pipe, can work at a high temperature of 1250 for a long time.

Anonymous users2024-02-09Summary. Metal materials with high temperature resistance of 1500 degrees, that is, metals with a melting point of more than 1500 are tungsten, rhenium, osmium, tantalum, niobium, iridium and other metals.
What are the steels that can withstand 1500 high temperatures for a long time?
Metal materials with high temperature resistance of 1500 degrees, that is, metals with a melting point of more than 1500 are tungsten, rhenium, osmium, tantalum, niobium, iridium and other metals.
High-temperature resistant stainless steel plate, also known as 310s (0cr25ni20) high-temperature resistant stainless steel plate, is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance, because the higher percentage of chromium and nickel makes it have much better creep strength, can continue to work at high temperatures, and has good high temperature resistance. Due to the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, high temperature resistance, and high temperature resistance, and the high-temperature resistant steel pipe is dedicated to the manufacture of electric furnace tubes and other occasions, after increasing the carbon content in austenitic stainless steel, the strength is improved due to its solution strengthening effect, and the chemical composition characteristics of austenitic stainless steel are based on chromium and nickel to add elements such as molybdenum, tungsten, niobium and titanium, and because its structure is a face-centered cubic structure, it has high strength and creep strength at high temperatures.

Virgin oils have a low smoke point, so try not to use them for frying and stir-frying, especially olive oil. In the past two years, the virgin olive oil that has been hyped in China has been blindly hyped, one or two hundred per bottle, and it smells bad when it is overburned, and it is not suitable for stir-frying. Pomace oil is used for frying in Western food, which is very cheap and not virgin, and many people don't know it. >>>More

There are several species commonly known as "fireproof trees" that are very resistant to high temperatures, and in the mountainous forests of western Guangdong in China, there is a kind of superba tree that is a fireproof expert and can curb the spread of flames. Its leaves have a moisture content of up to 45 and are scorched but not burned under a blazing barbecue. Its dense leaves, large coverage, and no weeds grow under the tree, so it can both prevent the spread of fire in the upper part of the canopy and the extension of flames on the ground. >>>More
