ASTM A242 has 2 grades: Type 1 and Type 2, while type 1 is the most used structural steel grade. Usually CCS grade D hull shipbuilding plate it is produced to be hot rolled state, it is suitable for cutting, forming, drilling and machining, grinding.
Our company was founded in 2000, which initially committed to providing high-quality steel CCS grade D hull shipbuilding 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 CCS grade D hull shipbuilding plate steel to the international market, opening up the international steel market.
Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld CCS grade D hull shipbuilding plate steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for CCS grade D hull shipbuilding plate manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The CCS grade D hull shipbuilding plate, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.
The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
