How to choose the suitable SG255 gas cylinder steel material?

SG255 is a steel specified in Japanese Industrial Standard JIS G 3116, which is commonly used in the manufacture of gas cylinders such as liquefied petroleum gas (LPG) and compressed natural gas (CNG). It has high strength and good weldability, plasticity and corrosion resistance, and can withstand heavy loads under high pressure. In addition, SG255 gas cylinder steel also has good formability and is easy to process into gas cylinders of various shapes and sizes during the production process, so it is widely used in the field of gas storage and transportation.

The selection of suitable SG255 gas cylinder steel material needs to consider the following factors:

1. Strength requirements: Determine the required minimum strength level according to the service conditions and pressure requirements of the gas cylinder.

2. Cost budget: On the premise of meeting the strength requirements, determine the range of available materials according to the budget.

3. Corrosion performance: Consider the corrosion performance of the medium inside the gas cylinder on steel to ensure that the selected SG255 gas cylinder steel can maintain good corrosion resistance for a long time.

4. Processing performance: Consider the machinability and formability of the selected material in order to manufacture parts that meet the design requirements of the gas cylinder.

5. Manufacturer reputation: choose the SG255 gas cylinder steel material supplied by well-known and standardized manufacturers to ensure quality and safety.
