What steel has good heat resistance and oxidation resistance

Heat-resistant steel has good heat resistance and oxidation resistance.

Alloy steel with high strength and good chemical stability at high temperatures.

It includes two types of oxidation-resistant steels (or high-temperature non-peeling steels) and heat-strong steels. Oxidation-resistant steels generally require good chemical stability but are subjected to lower loads. Thermally strong steels require high high-temperature strength and corresponding oxidation resistance.

Heat-resistant steels are commonly used in the manufacture of boilers, steam turbines, power machinery, industrial furnaces, and parts that work at high temperatures in industrial sectors such as aviation and petrochemicals. In addition to high-temperature strength and resistance to high-temperature oxidation and corrosion, these parts also require sufficient toughness, good machinability and weldability, as well as certain structural stability according to different applications. In addition, a number of new low-chromium-nickel have been developed.

Antioxidant steel grade.

Heat-resistant steel according to its normalizing.

The structure can be divided into austenitic heat-resistant steel, martensitic heat-resistant steel, ferritic heat-resistant steel and pearlitic heat-resistant steel.

Dear, I'm glad to answer your <>

Answer: The high-temperature resistant steel is made of steel 1Cr16Ni35: a steel grade with good carburizing resistance and nitriding resistance.

0Cr25Ni20: Furnace materials, automobile purification device materials 2Cr25Ni20 repeatedly heated oxidation resistant steel, furnace parts, nozzles, combustion chambers. 2cr25n:

High temperature corrosion resistance, below 1082 does not produce easy peeling oxide scale, used in combustion chambers.

Carbon steel: steel grades with good carburizing resistance and nitriding resistance; High chromium nickel austenitic stainless steel: materials for furnaces and automobile purification devices; Heat-resistant steel:

High temperature corrosion resistance, below 1,082 degrees Celsius, no easy peeling oxide scale, used in combustion chambers. The steel pipe made of stainless steel material is a stainless steel pipe.

Tungsten metal is the most heat-resistant:

1. Tungsten is a rare metal with a high melting point, the melting point of tungsten is 3410 degrees Celsius, belonging to the VIB group of the sixth period in the periodic system, tungsten is a silvery-white metal, the shape is like steel, the melting point of tungsten is high, the vapor pressure is very low, the evaporation rate is also small, the element symbol W, the atomic number is 74.

2. At room temperature, tungsten is very stable in the air, slightly oxidized at 400 degrees Celsius, and rapidly oxidized to form tungsten trioxide above 500 to 600 degrees Celsius, which does not interact with hydrogen, so its heat treatment process can be carried out under the protection of hydrogen. In nitrogen, the tungsten does not react until 2000 degrees Celsius. At red-hot temperatures, it can react with water vapor to form tungsten dioxide.

3. Tungsten is a rare metal, but also an important strategic material, China is a big tungsten producer, tungsten reserves of 5.2 million tons, accounting for 55% of the world's total reserves, production and exports are ranked first in the world, Hunan, Jiangxi and Henan provinces of tungsten resources reserves in the top three, of which Hunan, Jiangxi provinces good tungsten reserves account for 55% of the country, Hunan is dominated by scheelite, Jiangxi is dominated by wolframite, and its wolframite resources account for 40% of the total wolframite resources in the country.

Five carbide tetratantalum hafnium, melting point 4215 degrees Celsius.

Hafnium alloy contains the metallic element Hafnium Shenjinghafnium, which is the substance with the highest melting point in the world today. The substance with the highest known melting point is a compound of hafnium: pentacarbide tetratantalum hafnium with a melting point of 4215 degrees Celsius.

Tantalum carbide has the highest melting point (3983 °C), but hafnium carbide is also one of the alloys with the highest melting point (3928 °C). The tantalum-hafnium carbon alloy mentioned in the title is mentioned in Wikipedia, which is the highest melting point of any known compound.
