38CrMoAl is a near-AISI series chromium-molybdenum-aluminum alloy steel with high anti-corrosion, good heat-resistant and medium strength properties. The alloy has been widely used in many industrial sectors, such as oil and gas, mechanical engineering, and chemical engineering. This article introduces the application of 38CrMoAl steel.
In the oil and gas sector, 38CrMoAl steel is used as a high-pressure pipe, a main line pipe, a transportation pipes, a drilling string, and a line pipe for injecting gases into oil wells. It can resist high pressure and corrosion. It is used for long-length pipes, especially for offshore platforms, and for long-distance seam welding pipelines. The corrosion-resistant properties of 38CrMoAl ensure that the steel can work safely in higher pressure and harsh environments.
In the mechanical engineering sector, 38CrMoAl steel is commonly used for petrochemical equipment, turbine blades, compressor components, and other high-temperature and high-pressure parts. It also has excellent thermal stability and toughness and can be used for components for internal combustion engines and rotors for engines, compressors, and turbines. The wear-resistant properties make it a good choice for components such as valves and valve stems.
In chemical engineering, 38CrMoAl steel is used for the production of chemical reactors and container lids that operate at high temperatures and pressures. It is also used for the welding of pipelines due to its anti-corrosion properties. Additionally, the low sulfur content makes it a suitable choice for welding chemical pipelines, as sulfur can cause a chemical reaction when welding occurs.
In summary, 38CrMoAl is a near-AISI series chromium-molybdenum-aluminum alloy steel that has excellent properties such as anti-corrosion, good heat-resistance, and medium strength. It is widely used in various industrial sectors, such as oil and gas, mechanical engineering, and chemical engineering. It is used in high-pressure piping, petrochemical equipment, turbines, compressors, and chemical reactors. The low sulphur content makes it suitable for welding chemical pipelines.
