The functions of heat-resistant plates in boiler systems include: withstanding high temperatures and pressures, protecting the internal structure of the boiler, enhancing boiler efficiency, and ensuring safe operation. These plates can withstand high temperatures and pressures, preventing deformation or damage during operation due to temperature and pressure changes. They typically maintain their mechanical and physical properties at high temperatures, ensuring the safe operation of the boiler.
Products Description
1.4743 is a high chromium heat resistant cast steel with excellent heat resistance and wear resistance. The material is mainly composed of iron, chromium, silicon and other elements, which are alloyed through specific processes. Its chemical composition and physical properties are as follows:
Chemical composition Iron (Fe): 70%~80% Chromium (Cr): 15%~18% Silicon (Si): 1%~3% Other impurities: less than 1% .
Physical properties Hardness (HB): ≥200 Tensile strength (MPa): ≥600 Yield strength (MPa): ≥350 Fracture toughness (J/cm^2): ≥40 Linear expansion coefficient (10^-6/℃): 11.5~14.5
2. Application fields of 1.4743 Due to its excellent heat resistance and wear resistance,
1.4743 is widely used in the following fields:
Boiler parts of thermal power plant: Because the working environment temperature of thermal power plant boiler is high, the heat resistance performance of materials is required to be higher, so 1.4743 is often used to make heat-resistant parts of boiler, such as grate, furnace door, etc.
Petrochemical equipment: In the high temperature working environment of the petrochemical industry, 1.4743 can maintain good stability and wear resistance, and is widely used in the parts of petrochemical equipment, such as oil heating furnace pipeline, catalyst, etc.
Metallurgical equipment: In the high temperature smelting process of metallurgical industry, 1.4743 is often used to make refractory bricks, furnace body and other refractory materials to improve the service life and stability of refractory materials.
According to the requirements of different application fields, the parameters of 1.4743 have certain diversity. The following is an analysis of some common parameters:
Hardness: Hardness is an important index to measure the compressive resistance of materials. Different fields have different requirements for hardness. By adjusting the content of chromium and silicon, hardness can be controlled to meet the needs of different application fields.
Wear resistance: Wear resistance refers to the durability of materials in the friction or wear environment. By reasonably controlling the content of alloy elements and adding appropriate wear resistance elements, the wear resistance of materials can be improved.
Oxidation resistance: In high temperature environment, materials tend to be oxidized, which affects their performance. By adding appropriate amount of oxidation resistant elements, such as chromium, aluminum, etc., the oxidation resistance of materials can be improved and the service life can be extended.
