タイトルまたは説明

AS*******0 steel plate is a carbon steel plate used for conventional structures, which has advantages such as high strength, wear resistance, corrosion resistance, and heat resistance. It is widely used in various buildings, engineering, and mechanical equipment.

Overall, the development prospects of AS*******0 steel plate are relatively stable. In the future, the steel industry will continue to be guided by energy conservation and environmental protection, eliminate outdated production capacity and equipment, promote technological transformation and product upgrading, and improve steel quality and performance. This will bring good opportunities for the production and application of AS*******0 steel plates.

In addition, as people's requirements for construction projects such as buildings and bridges become increasingly high, the demand for high-quality, high-performance, and highly reliable steel will further increase. AS*******0 steel plate has these characteristics, so it has good market prospects.

The tensile strength of AS*******0 steel plate is **5MPa, the yield strength is **0MPa, and the elongation is above *0%. It is widely used in fields such as bridges, mechanical manufacturing, and conveying equipment. During use, attention should be paid to controlling the processing temperature and cooling rate of the steel plate to ensure its quality and performance.

Characteristics of SA**3GrA/B/C/D steel plate

SA**3GrA/B/C/D steel plate is suitable for riveting, bolted connection, and welding structures of bridges and buildings. It is a high-quality carbon structural steel for general structural steel. SA**3GrC is mainly used in the petroleum and petrochemical industry, chemical equipment manufacturing enterprises, power station construction, boiler and pressure vessel manufacturing, and other enterprises to collaborate with Wugang to produce SA**3GrC for the production of reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, liquefied petroleum gas cylinders, and turbine volutes. Due to the harsh usage conditions in petrochemical, coal conversion, nuclear power, steam turbine cylinder bodies, thermal power, and other industries, Among them, large equipment with complex corrosive medium, such as water scrubber, second shift furnace, coke tower, desulfurization tank, conversion gas waste heat boiler, Methanation furnace, reactor, regenerator, hydrogenation reactor, Methanation heater, conversion gas steam generator, etc.

The performance of carbon steel mainly depends on its carbon content. As the carbon content increases, the strength and hardness of the steel increase, while the plasticity, toughness, and weldability decrease. Compared with other types of steel, carbon steel is used earlier, has a wide range of performance, and is used in larger quantities. Suitable for media such as water, steam, air, hydrogen, nitrogen, and petroleum products with a nominal pressure of PN ≤ *2.0MPa and a temperature of ******5 ℃.

â‘  Sulfur, oxygen, and nitrogen can all increase the thermal brittleness of steel, while an appropriate amount of manganese can reduce or partially offset its thermal brittleness.

â‘¡ Residual elements, except for manganese and nickel, reduce the impact toughness of steel and increase cold brittleness.

â‘¢ Except that sulfur and oxygen reduce the strength, other impurities increase the strength of steel to varying degrees.

â‘£ Almost all impurity elements can reduce the plasticity and weldability of steel.

Hydrogen can cause many serious defects in steel, such as white spots, point like segregation, hydrogen embrittlement, surface bubbling, and cracks in the weld heat affected zone. To ensure the quality of steel, it is necessary to minimize the hydrogen content in the steel as much as possible. The residual elements introduced by deoxidation, such as aluminum, can reduce the aging tendency of low-carbon steel, refine grain size, and improve the toughness of steel at low temperatures, but the margin should not be too large.
