With the growing demand for high-temperature environment operations in the global industrial field, heat-resistant steel is becoming an indispensable basic material for key industries such as energy, chemical industry, and metallurgy due to its excellent high-temperature resistance, corrosion resistance and high-strength characteristics. In recent years, the application scenarios of heat-resistant steel have continued to expand, and technological iterations have also promoted the Uppgradering av relaterade industrikedjor .
In the field of energy and power, heat-resistant steel is the core material for the manufacture of thermal power boilers, gas turbines and nuclear power equipment. Supercritical and ultra-supercritical units have higher requirements for the high-temperature resistance of boiler pipes. The new heat-resistant steel significantly improves the creep resistance of materials in environments above 600℃by optimizing the Förhållandet mellan legeringselement såsom krom, molybden och nickel och förlänger livslängden för utrustningen . Samtidigt har kraven med högt temperatur i det nya energifältet.}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}.
In the chemical industry, heat-resistant steel is widely used in high-temperature and high-pressure equipment such as hydrogenation reactors and cracking furnaces. The operating temperature of the ethylene cracking unit often reaches 800℃to 1100℃. Heat-resistant steel improves the grain boundary strength by adding rare earth elements, effectively solving the oxidation and sulfidation corrosion problems Av materialet under extrema förhållanden . Dessutom, i petroleumförädlingskatalytisk sprickenhet, minskar appliceringen av värmebeständig stålfoder avsevärt utrustningens underhållskostnad .
The metallurgical and mechanical manufacturing fields also benefit from the technological progress of heat-resistant steel. After the slide rails and refractory support parts of the rolling furnace are made of heat-resistant steel, the thermal fatigue resistance is improved by more than 30%. Aerospace engine combustion chambers, automotive turbochargers and other components rely on heat-resistant steel to uppnå en balans mellan lätt och hållbarhet .
At present, heat-resistant steel is developing towards higher temperature grades and longer service life. With the breakthrough in the application of 3D printing technology in high-temperature alloy forming, the manufacturing efficiency of customized heat-resistant steel parts has been significantly improved. In the future, with the rise of emerging industries such as hydrogen energy and energy storage, the market demand for heat-resistant steel is expected to släpps vidare, vilket ger mer pålitliga lösningar för den globala högtemperaturindustrin .
