The yield strength of A40, D40, E40 and F40 BV FH36 offshore structural steel plate is not less than 390N/mm^2, and the tensile strength is 510~660N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20 ° respectively. Impact toughness BV FH36 offshore structural steel plate that can be achieved at -40℃, -60℃.
A small amount of Nb is sufficient to obtain excellent comprehensive properties of BV FH36 offshore structural steel plate etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of BV FH36 offshore structural steel plate and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.
With the continuous development of foreign business, our company has achieved pleasant cooperation with a number of freight companies, including international air transport (including international express) and sea bulk cargo, we can provide the best service. In order to better develop the air transport from mainland to foreign countries, so that the goods can be transferred in Hong Kong in a timely manner.
