China sa588 grade a steel material price

The weldability of sA588 Grade A steel material is good. It means that under certain process and construction conditions, sA588 Grade A steel material can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

On March 17, the Ministry of Finance and the State Administration of Taxation jointly issued the announcement on increasing the export tax rebate rate of some products, and the relevant adjustments will be implemented from March 20. This adjustment involves 60 tariff numbers of steel products. After the adjustment, the sA588 Grade A steel material etc. steel products with the original export tax rebate rate of 10% will be fully refunded, which is great news for both steel exporters and our customers.

The characteristic of niobium in sA588 Grade A steel material etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.

sA588 Grade A steel material, S355J2WP plate is a high phosphorus corrosion resistant structural steel, and P is the chemical element phosphorus. S355J2WP steel enhances the atmospheric corrosion resistance applied at ambient temperature. In order to achieve the corrosion resistance, some specific alloy elements, such as P, Cu, Cr, Ni, Mo, etc., are added to form a protective oxide layer on the metal surface under various climatic conditions.
