Factory price export equivalent grades of raex 500 steel to South Africa

BBN company is one of the most important manufacturers of equivalent grades of raex 500 medium and heavy steel plates for shipbuilding in China. The general strength shipbuilding steel Grades A, B, D, E and higher-strength grade AH32, AH36, DH32, DH36, EH32, EH36 hull structural steel plates produced by heavy steel (specifications: 6-32mm) have been obtained by nine classification society approval certificates Like ABS, CCS, LR, DNV, GL, RINA, and KR.

Executive Standards of our equivalent grades of raex 500, steel plate products: according to the user's requirements, the steel plate can be delivered according to the following standards: national standards, metallurgical industry standards, American ASTM, ASME standards, Japanese JIS, German DIN, British BS, European EN, international ISO standards and relevant standards of special plate. The ship plate can be certified by ABS LR DNV CCS BV KR NK GL RINA.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of equivalent grades of raex 500 nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of equivalent grades of raex 500 steel, can be used as an alloying element of low alloy steel.

equivalent grades of raex 500 product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering
