JIS G3115 SPV 355 for medium-temperature pressure vessel

1.What are the chemical composition of JIS G3115 SPV355 pressure vessel?

2.What are the main characteristics of JIS G3115 SPV 355 medium-temperature pressure vessel plates?

High strength and good toughness: It can maintain stable performance in harsh working environments, withstand various external forces such as impact and tension, and absorb a large amount of energy when impacted, reducing the risk of equipment damage and personnel injury.

Good weldability: It can be connected by various welding methods such as manual arc welding, submerged arc welding, and gas – shielded welding, which is convenient for manufacturing pressure vessels of various complex shapes and structures, improving production efficiency and reducing manufacturing costs.

Resistant to high temperature and high pressure: It can maintain stable mechanical properties and corrosion resistance in high – temperature environments without problems such as thermal expansion or contraction due to temperature changes. It can also withstand high pressure without deformation or rupture.

3.In what state are JIS G3115 SPV 355 medium-temperature pressure vessel plates generally delivered?

It can be delivered in hot – rolled or normalized states. For some applications with high – performance requirements, the normalized heat – treatment process is usually adopted.
