Our company was founded in 2000, which initially committed to providing high-quality steel RD 40 shipbuilding marine grade steel plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export RD 40 shipbuilding marine grade steel plate steel to the international market, opening up the international steel market.
A203GrD steel plate belongs to ultra-low temperature container plate. ASTM A203 is a low-nickel alloy steel, including five grades A, B, D, E, and F. Among them, Grades D, E, and F have a nominal nickel content of 3.5%, commonly known as 3.5Ni steel. A203D/E/F steel has good impact toughness and mechanical properties in a low temperature environment, and is usually used in a low temperature environment of -70～-101℃ (the tempered state can reach -107℃).
The boiler steel pipe has excellent anti-oxidation and corrosion performance: the general steel pipe is easy to be corroded under high temperature and produces harmful substances, but the boiler steel pipe has no such worries. The high-precision material and wall thickness of the boiler steel pipe can effectively prevent the corrosion. Good tensile strength of RD 40 shipbuilding marine grade steel plate, boiler steel pipe: it can keep the original state well without affecting its quality after being heated and stretched.
The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, RD 40 shipbuilding marine grade steel plate. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.
The requirements for toughness impact energy of RD 40 shipbuilding marine grade steel plate, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.
