SA588 grade A carbon steel plate sheet application and heat treatment

HP295 is mainly used in the manufacture of liquefied gas cylinders, its SA588 grade A carbon steel plate sheet chemical composition is stable, P, S content is low, pure steel, the internal organization, fine grain. Moderate strength, good plasticity, low yield ratio, yield platform is not obvious, vertical and horizontal performance of small differences, excellent cold stamping performance.

Compared with thick steel plates, SA588 grade A carbon steel plate sheet, thin steel plates have many obvious advantages in steel plate processing and use. It is precisely these advantages of thin steel plates that make them more and more popular in various industries. First, compared to those thicker steel plate materials, thin steel plates are generally thinner in thickness. Thin steel plates themselves are lighter and thinner, and their weight is lighter, which is very convenient for handling during construction and transportation. It can save some storage and transportation space.

The preparation of SA588 grade A carbon steel plate sheet galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for SA588 grade A carbon steel plate sheet centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate SA588 grade A carbon steel plate sheet EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

Both parties shall confirm the SA588 grade A carbon steel plate sheet material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the SA588 grade A carbon steel plate sheet steel plant.
