SG325 hot rolled steel plates information

SG325 hot rolled steel plates are mainly used in gas cylinders and canisters, which are used to store and transport compressed gases such as liquefied petroleum gas (LPG), acetylene, and oxygen. SG235 Gas Cylinders Steel plates are made of high-quality carbon steel and are known for their excellent durability, strength, and corrosion resistance.

The chemical composition of SG325 hot rolled steel plates include C, Si, Mn, P, S, and Al. The maximum carbon content in these plates is 0.20%, while the maximum silicon content is 0.55%. The plates have a maximum manganese content of 1.50%, a maximum phosphorus content of 0.040%, and a maximum sulfur content of 0.040%. Additionally, the plates have a maximum aluminum content of 0.015%.

The mechanical properties of SG325 hot rolled steel plates include tensile strength, yield strength, elongation, and impact resistance. The plates have a minimum tensile strength of 490MPa and a minimum yield strength of 325MPa. The elongation at break is typically between 22% and 28%, depending on the plate thickness, while the impact resistance is 27J at -20°C.

SG325 hot rolled steel plates are produced by a hot rolling process, which involves heating steel slabs to a temperature between 1,100°C and 1,300°C and then rolling them into thin sheets with a thickness of between 1.2mm and 12mm. The sheets are cooled rapidly to room temperature to ensure that they retain their strength, durability, and dimensional stability.

The use of SG325 hot rolled steel plates in gas cylinders and canisters offers several advantages over other materials. For one, these plates are lightweight, which makes them ideal for portable and stationary gas storage applications. They are also highly durable and resistant to corrosion, which helps to extend the lifespan of gas cylinders and canisters.

In addition, SG325 hot rolled steel plates have excellent formability, which allows them to be used in a wide range of applications beyond gas storage and transportation. For example, they can be used in the construction of pressure vessels, boilers, and heat exchangers, as well as in the manufacture of pipes, tubes, and other structural components.

To ensure the safety and reliability of gas cylinders and canisters, SG325 hot rolled steel plates are subjected to rigorous quality control measures during production. These measures include high-pressure testing, ultrasonic testing, and visual inspection to ensure that the plates meet strict industry standards for safety and performance.

In terms of storage and handling, SG325 hot rolled steel plates should be kept in a dry and clean environment to prevent corrosion and other forms of damage. They should be stored in a flat and level position, preferably on a dry surface, to prevent warping and bending. When handling the plates, care should be taken to avoid scratching or damaging their surfaces.

SG325 hot rolled steel plates are an excellent choice for gas storage and transportation applications due to their strength, durability, and corrosion resistance. They are lightweight and highly formable, which makes them ideal for a wide range of other applications as well. To ensure their safety and reliability, these plates are subjected to rigorous quality control measures during production. Proper storage and handling are also important to prevent damage and ensure their long-term performance.
