The ASTM A516 Grade 60 plate is one of the most commonly used carbon steel for pressure vessel applications. This ASTM A516 Gr.60 Plate is intended for welded pressure vessels with critical notch toughness. The A516 Grade 60 plate has excellent welding characteristics and is ideal for pressure vessels in moderate and low-temperature service. In this comprehensive guide, we will explore the various aspects of the ASTM A516 Grade 60 plate.
What is ASTM A516 Grade 60 Plate?
Grade 60 Plate is a carbon steel plate intended primarily for service in welded pressure vessels at moderate or lower temperatures, where notch toughness is important. It is widely used in the fabrication of industrial boilers and tanks and chemical and petrochemical process equipment ranging from piping systems to rebar-lined storage tanks. SA516 Grade 60 Plate offers excellent corrosion resistance along with good strength at low-temperature levels.
ASTM A516 Grade 60 Plate Chemical Composition
ASME SA516 Grade 60 carbon steel plates is a medium carbon alloy that contains manganese, phosphorus, sulfur, and silicon as the main chemical elements. It also contains small amounts of chromium, molybdenum, aluminium, nickel, and vanadium for improved strength. The plate exhibits good machinability and excellent weldability qualities with a low brittle transition temperature. The composition makes it ideal for pressure vessel applications requiring high strength-to-weight ratios.

SA516 Grade 60 Plate Uses
ASTM A516 Grade 60 Plate is widely used in various industries and applications due to its excellent strength, different properties, and ability to withstand pressure. Commonly,SA516 Grade 60 can be found in construction or manufacturing-related industries for use as welded structural elements such as pipelines or buildings. It is also frequently utilized by engineering companies requiring more tough components for pressurized vessels and boilers operating at elevated pressures and temperatures.
ASTM A516 Gr 60 Plate Heat Treatment
Heat treatment for ASME SA516 Gr 60 plates involves heating the material to between 650 and 750°C, holding it at the temperature, and then cooling it down in an air-cooled or controlled atmosphere furnace. Slow cooling rates will minimize internal stresses and prevent cracks from forming during the cooling-off period. Depending on the levels of carbon present in the alloy (which determines its hardness), some heat treatments may involve a post-annealing/normalizing process to ensure dimensional stability and reduce distortion caused by internal stresses.
ASTM A516 Gr 60 Plate Manufacturing Process
The ASTM A516 Gr 60 uses hot rolling. This process involves heating the steel slab to a high temperature and then rolling it to the desired thickness. The plate is then cooled to room temperature and quality checked. The plate is available in various thicknesses and sizes to meet customer requirements.
ASTM A516 Gr 60 Plate Corrosion Resistance
ASTM A516 Grade 60 plates are designed to provide exceptional corrosion resistance. This alloy is composed of chromium, manganese, silicon, and nickel-based on its composition. It also offers excellent oxidation and general corrosion properties due to the presence of these elements. Moreover, ASME SA516 Grade 60 Plate also features an increased level of carbon content that gives it improved mechanical properties such as flexibility and strength, further improving its resistance against aggressive environments.
Conclusion:
The ASTM A516 Grade 60 plate is a high-quality carbon steel plate with excellent mechanical properties and welding characteristics. It is primarily used in pressure vessel applications due to its high-notch toughness. The plate is manufactured using the hot rolling process and undergoes stringent quality control and testing procedures to ensure it meets the required standards. If you need a reliable plate for pressure vessel applications, the ASME SA516 Grade 60 plate is an excellent choice. It is readily available in different sizes and thicknesses to meet your requirements.
