The A204/A204M-17 steel grade is a type of low-alloy, pressure vessel-grade steel commonly used in the manufacturing of boilers and pressure vessels. It is specifically designed to have high strength and excellent corrosion resistance, making it suitable for use in harsh environments.
One key characteristic of the A204/A204M-17 steel grade is its chemical composition, which is primarily composed of carbon, manganese, silicon, and molybdenum. The carbon content helps to provide strength and hardness, while the manganese content improves the overall toughness of the steel. The silicon content enhances the steel’s ability to resist oxidation and corrosion. The addition of molybdenum significantly improves the steel’s high-temperature strength and corrosion resistance.
In terms of mechanical properties, the A204/A204M-17 steel grade has a minimum yield strength of 255 MPa (37 ksi) and a minimum tensile strength of 485-620 MPa (70-90 ksi). It also has a maximum thickness limit of 150mm (6 inches).
The A204/A204M-17 steel grade is commonly used in the fabrication of boilers and pressure vessels for various industries including oil, gas, chemical, and petrochemical. Due to its high strength and corrosion resistance, it can withstand high-pressure environments and harsh operating conditions.
In summary, the A204/A204M-17 steel grade is a low-alloy, pressure vessel-grade steel with high strength, excellent corrosion resistance, and good mechanical properties. Its chemical composition and mechanical properties make it suitable for use in boilers and pressure vessels in various industries.
