What is CCS grade D hull shipbuilding plate carbon content

Shipbuilding steel plate as a kind of specialized steel plate is used for shipbuilding and offshore platforms. BBN steel is able to supply various kinds of marine steel plates, steel sections and steel structures including general strength shipbuilding steel plates, CCS grade D hull shipbuilding plate,high strength shipbuilding steel plates and ultra high strength shipbuilding steel plates. The nominal yield strength of the steel plate is in the range of 235MPa to 690MPa. Its actual yield strength is superior to its nominal strength in general.

The company will also put Georgetown steelworks on "care and maintenance mode" and temporarily lay off or redeploy about 130 employees working at the steelworks and contractors while some CCS grade D hull shipbuilding plate maintenance employees will be on staff during the closure. It is stated that unemployment insurance and state-based unemployment support will be available immediately to workers affected by these changes.

The rolling pipe is made by steel plate with welding process. The rolling pipe is mainly used for conveying water, gas, air, oil and hot water or steam, etc. The rolling pipe has the following characteristics. First, it is easy to process. Welding can be done directly on the basis of steel plates, CCS grade D hull shipbuilding plate. Second, the diameter is large, and various large-diameter rolling pipes can be directly customized and processed. Third, the processing speed is fast, saving processing time. Fourth, a small amount of customization can be used for trial proofing to avoid excessive waste.

The main function of boron in CCS grade D hull shipbuilding plate and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
