SG255 hot rolled gas cylinder steel plates information

SG255 hot rolled gas cylinder steel plates are widely used in liquefied petroleum gas cylinders, air pressure vessels, and gas tanks. SG255 gas cylinder steel material is characterized by high strength, good plasticity, toughness, and excellent mechanical properties. This article will provide information regarding the properties, applications, and production process of SG255 hot rolled gas cylinder steel plates.

Properties of SG255 Hot Rolled Gas Cylinder Steel Plates:

1. High strength: SG255 has a minimum tensile strength of 400MPa and a minimum yield strength of 255MPa.

2. Good plasticity: SG255 has good elongation, bending, and drawing properties.

3. Excellent mechanical properties: SG255 can withstand high pressure, impact, and fatigue.

4. Great weldability: SG255 can be welded with various welding methods such as arc welding, resistance welding, and gas welding.

Applications of SG255 Hot Rolled Gas Cylinder Steel Plates:

SG255 hot rolled gas cylinder steel plates are widely used in liquefied petroleum gas cylinders, air pressure vessels, and gas tanks. The material is used for both the outer shell and the components of the cylinder. Here are some applications of SG255 hot rolled gas cylinder steel plates:

1. Liquefied Petroleum Gas Cylinders: SG255 is used for the production of liquefied petroleum gas cylinders in which the gas is stored under high pressure. The material is used for the cylinder body and the bottom plate.

2. Air Pressure Vessels: SG255 is also used for air pressure vessels such as compressed air tanks and air pressure receivers. The material is used for the body and the end caps of the vessels.

3. Gas Tanks: SG255 is used for the production of gas tanks in which gas is stored under pressure. The material is used for the cylinder body and the bottom plate.

Production Process of SG255 Hot Rolled Gas Cylinder Steel Plates:

JIS G 3116 SG255 gas cylinder steels are produced using a hot rolling process. Here are the steps involved in the production process:

1. Raw Material: High-quality raw materials are used for the production of SG255 hot rolled gas cylinder steel plates. The raw material should meet the chemical composition and mechanical property requirements.

2. Heating: The raw material is heated in a furnace to a temperature of about 1250°C.

3. Roughing Mill: The heated raw material is then passed through a roughing mill, which reduces its thickness and changes its shape.

4. Intermediate Mill: The material is then passed through an intermediate mill, which further reduces its thickness.

5. Finishing Mill: The material is then passed through a finishing mill, which gives it the final thickness, shape, and surface finish.

6. Cooling: The finished product is then cooled using either air or water to room temperature.

7. Cutting: The cooled product is cut into the required length using a saw or a shear.

8. Inspection: The finished product is then inspected for its quality, including its chemical composition, mechanical properties, and surface finish. It is also checked for any defects such as cracks, voids, or other imperfections.
