Introduction

Pressure plate SA516GR70 is a carbon steel material that complies with European standard EN 10028-2 and is mainly used in the manufacture of boilers, pressure vessels and other equipment that need to withstand high temperatures and pressures.

Advantages

1.Good pressure bearing capacity
The tensile strength range of pressure plate SA516GR70 is 470-650 MPa, and the minimum yield strength is 355 MPa, which ensures stability under high pressure conditions and avoids plastic deformation. In addition, the maximum pressure is 0.025 and the maximum absorption is 0.015, indicating that the steel plate can withstand high internal and external pressures and has good bearing capacity, which is suitable for use in high-pressure equipment such as pressure vessels and boilers.

2.Good toughness
The minimum elongation of pressure plate SA516GR70 within 2 inches (50 mm) is 20%. The higher elongation means that the material can produce a certain deformation during the stress process instead of sudden breakage. Steel plates with high elongation can better cope with the needs of complex working conditions such as vibration, impact or dynamic loads, and ensure the long-term stability of equipment or structures during use.

3.Adapt to various temperature environments
At temperatures of +20℃, 0℃ and -20℃, the P335GH pressure plate SA516GR70 can pass the impact test, which is suitable for applications in cold areas or low temperature environments, and can withstand impact loads at lower temperatures.

4.Low carbon content improves weldability
The carbon content of the pressure plate SA516GR70 is between 0.1-0.22%. During the welding process, the high-temperature brittleness caused by low carbon steel is reduced, and it is easier to produce a stable metal structure at the welded joint, and it is not easy to crack. Especially when welding at high temperatures, the material will not become brittle due to excessive carbon content.

5.Wear resistance
The manganese content is between 1.1-1.7%, and the silicon content is up to 0.6%. The addition of these two elements improves the wear resistance of the material, especially for corrosive environments such as petrochemicals, and prolongs the service life of the material.
