Definition of "Low-alloy high-strength": Based on ordinary carbon steel (such as Q235), a small amount (usually <3% total) of alloying elements, such as manganese (Mn), silicon (Si), vanadium (V), niobium (Nb), and titanium (Ti), are added. These elements significantly improve the strength of the steel through mechanisms such as grain refinement and precipitation strengthening, while maintaining good plasticity and toughness.
- High Strength: The yield strength is approximately 47% higher than Q235 (235MPa), meaning that less material can be used under the same load, achieving weight reduction and material savings.
- Good Comprehensive Mechanical Properties: While significantly improving strength, it still maintains excellent plasticity, toughness, cold bending performance, and weldability.
- Economy: Although the unit price is slightly higher than Q235, its overall economic benefits are very prominent due to the reduced material usage and superior structure.

The use of pressure vessels is very wide. It is an equipment that plays an important role in various sectors of the national economy such as the petrochemical industry, energy industry, scientific research industry.
The pressure vessel is generally composed of six parts: a cylinder, a head, a flange, a sealing element, an opening, a nozzle, and a support. In addition, it is also equipped with safety devices, meters and internal parts to complete the role of different production processes. Due to reasons such as sealing, pressure bearing and medium, pressure vessels are prone to explosions, fires and accidents that endanger the safety of personnel, equipment and property, and pollute the environment.
