Get ready to dive into the world of metal fabrication with a side-by-side comparison between SA 387 Gr 11 Plates and other types of steel plates!
What is SA 387 Gr 11 Plates?
SA 387 Gr 11 Plates are chromium molybdenum alloy steel plates primarily used in pressure vessels, heat exchangers and boilers at high temperatures. They are made of chromium-molybdenum alloy with an added amount of carbon, which increases their strength and provides outstanding corrosion resistance properties. Despite extreme working conditions, these stainless steel plates offer excellent oxidation and corrosion resistance due to their superb tensile strength and low-temperature toughness. In addition, they have superior creep characteristics making them the ideal choice for various engineering projects where weight savings is critical.
What are Steel Plates?
Steel plates are large pieces of metal, typically in flat shapes with squared corners and sides, used in various applications across many industries. Generally made from iron or steel alloy that is heated and hammered into shape, steel plates provide strength and durability for structures such as bridges, ships, buildings, vehicles, railroads, industrial machinery and equipment frames. Steel plates are also found in everyday products such as kitchen appliances and furniture components. Their heat-resistant qualities make them ideal for fabricating cookware.
Different Between SA 387 Gr 11 Plates and Other Types of Steel Plates
SA 387 Gr 11 plates are a chromium-molybdenum alloy steel type ideal for use in high-temperature environments. These plates have excellent corrosion and oxidation resistance, making them a popular choice for various industries such as chemical, petrochemical, and power generation. SA 387 Gr 11 plates also have good tensile and yield strength, making them suitable for high-temperature services such as boiler applications.
Compared to SA 387 Gr 11 plates, carbon steel plates are popular due to their affordability and wide availability. However, carbon steel plates are not recommended for high-temperature environments due to their low thermal conductivity. Carbon steel plates also have poor corrosion resistance, making them unsuitable for harsh environments. On the other hand, stainless steel plates have excellent corrosion resistance but lack the strength for high-temperature applications.
In contrast, SA 516 Gr 70 plates are another steel plate often used in boiler applications. While SA 516 Gr 70 plates have good tensile strength, they do not possess the same corrosion and oxidation resistance level as SA 387 Gr 11 plates. SA 516 Gr 70 plates are also susceptible to brittle fracture at low temperatures, making them unsuitable for cryogenic applications.
Overall, SA 387 Gr 11 plates offer a unique combination of strength and resistance to high-temperature and harsh environments. Compared to carbon steel plates, SA 387 Gr 11 plates offer superior corrosion and oxidation resistance while maintaining good tensile and yield strength. Compared to SA 516 Gr 70 plates, SA 387 Gr 11 plates have better resistance to oxidation and corrosion, making them a better choice for high-temperature environments.
In conclusion, when selecting the right type of steel plate for your project, it’s crucial to consider factors such as the application, environment, and temperature requirements. SA 387 Gr 11 plates offer excellent resistance to high-temperature and harsh environments, making them ideal for various industrial applications. Compared to other types of steel plates, SA 387 Gr 11 plates offer superior corrosion and oxidation resistance while maintaining good tensile and yield strength, making them a reliable and cost-effective choice for your next project.
