ASTM A516 Grade 60 HIC (Hydrogen-Induced Cracking) plates are widely used in industries that require pressure vessels and boilers to withstand hydrogen-induced cracking in wet, sour service environments. These plates are made especially to increase safety and durability of such equipment by resisting the harmful effects of hydrogen embrittlement. In this blog, we will dive into the key properties and uses of ASTM A516 GR. 60 HIC plates.
Key Properties of ASTM A516 GR. 60 HIC Plates
- Hydrogen Induced Cracking (HIC) Resistance
One of the primary properties of SA 516 GR.60 HIC Plates is their enhanced resistance to hydrogen-induced cracking. This is particularly important in environments where hydrogen sulfide (H2S) is present, such as in sour gas fields and petrochemical applications.
- High Strength and Toughness
ASTM A516 Grade 60 plates are known for their high tensile strength and toughness, making them suitable for applications requiring robust performance under pressure. The plates have a tensile strength ranging between 415 and 550 MPa, making them ideal for heavy-duty applications.
- Excellent Weldability
These plates are highly weldable, meaning they can be easily fabricated and incorporated into various structures without compromising their mechanical properties. This is a significant advantage in industries like oil and gas, where complex pressure vessels need to be assembled with precision.
- Resistance to Corrosion
While the main focus is on HIC resistance, ASTM A516 GR. 60 HIC plates also offer good resistance to general corrosion, which further extends their lifespan in harsh environments.
- Temperature Resilience
The plates work effectively in a variety of temperatures, thus they may be used for both low and high-temperature applications in pressure vessels and boilers.
Common Uses of ASTM A516 GR. 60 HIC Plates
- Oil and Gas Industry
In the oil and gas sector, especially in sour service applications where hydrogen sulfide is prevalent, these plates are used in the construction of pressure vessels, storage tanks, and pipelines. Their resistance to hydrogen-induced cracking ensures long-lasting performance and reduced maintenance.
- Chemical and Petrochemical Plants
Chemical industries that work with corrosive substances often use ASTM A516 GR. 60 HIC plates in their equipment, including reactors, heat exchangers, and distillation columns. These plates ensure that the equipment operates safely under high pressure and exposure to hydrogen.
- Power Generation
Power plants, especially those dealing with heavy fuel oil and sour gas, incorporate these plates into their boilers and pressure vessels to ensure reliability and safety. The plates’ ability to withstand high temperatures and pressure is crucial in maintaining the integrity of such systems.
- Pressure Vessels and Boilers
ASTM A516 GR. 60 HIC plates are commonly used in pressure vessels and boilers due to their excellent strength and durability. These applications require materials that can handle both high-pressure conditions and potential exposure to hydrogen, making HIC-resistant plates essential.
- Refineries
In refineries, where hydrogen is a by-product, and the risk of hydrogen embrittlement is high, ASTM A516 GR. 60 HIC plates are used for constructing storage tanks and other essential equipment.
Conclusion
ASTM A516 GR. 60 HIC plates are vital in industries where resistance to hydrogen-induced cracking and excellent mechanical properties are necessary for safety and efficiency. Their applications in oil and gas, petrochemicals, power generation, and pressure vessel construction highlight their versatility and importance. When you need a material that can endure the rigors of harsh, high-pressure environments, ASTM A516 GR. 60 HIC plates offer a reliable and durable solution.
