Detailed analysis of properties of SG255 steel plate

SG255 is a high-strength gas cylinder steel whose chemical composition mainly includes elements such as carbon, silicon, manganese, phosphorus and sulfur. It has good processability, weldability and corrosion resistance, and exhibits excellent mechanical properties under high pressure.

The standard thickness of SG255 steel plate is 2.8mm to 6.0mm, and the standard width is 900mm to 1600mm. The steel is commonly used in the manufacture of pressure vessels such as liquefied petroleum gas (LPG) and natural gas, and equipment such as gas cylinders and gas tanks.

For the performance index of SG255 steel, the following is a detailed introduction:

1. Tensile strength: ≥400MPa;
2. Yield strength: ≥255MPa;
3. Elongation: ≥28%;
4. Impact toughness: ≥27J at -20°C.

It should be noted that the above values are for reference only, and should be selected according to specific conditions in actual applications.
SG255 steel is a high-strength gas cylinder steel material with the following properties and applications:

Properties of SG255 steel: high strength and good plastic deformation ability, excellent welding performance and reliable sealing performance, good low temperature impact toughness and corrosion resistance

Application of SG255 steel plate: It is used to manufacture pressure vessels or cylinders such as liquefied petroleum gas, liquefied natural gas, industrial gas, etc. It can also be used to manufacture equipment or components that need to withstand high pressure, such as gas pipelines, engine oil tanks, and automotive fuel tanks.
