a36 ship steel sheet and so on marine engineering steels are suitable for various complex working conditions and harsh natural environment, and their service life is 50% higher than that of ordinary marine steel. Therefore, marine engineering steel is required to not only have high strength and high plasticity, good welding performance and seawater corrosion resistance, but also have good toughness, so as to ensure that steel and equipment can adapt to various loads and low temperature environment.
Titanium microalloying is an element of a36 ship steel sheet strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in a36 ship steel sheet tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
In view of the characteristics of container transportation, such as high added value, low cargo damage and short time, our company takes more consideration of port collection and distribution conditions, port facilities, flight density and route coverage when choosing ports. For the convenience of customers, as well as the safety of goods.
