CCS China Classification Society certification, CCSDH620 marine structural steel, DH620 ship plate s

CCSDH620 is China Classification Society certified marine structural steel, D is the quality grade (-20°C low temperature impact), H is the high strength steel, and 620 represents the yield strength. CCSDH620 is a marine steel plate, which is often used in the marine manufacturing industry, such as ship equipment, offshore platform construction, marine engineering, derricks, leg piles, pillars, marine equipment, port machinery, etc.,

and CCSDH620 steel plate fixed rolling # Wugang Xiangyang #

CCSDH620 can be done according to different needs 'normalizing + tempering, quenching, hot rolling, etc.

CCSDH620 can implement the certification standards of nine classification societies: China CCS, American ABS, German GL, French BV, Norwegian DNV, Japanese NK, British LR, Italian RINA, South Korean KR, (Norway DNV and Germany merged to: VL).

Chemical composition of CCSDH620 marine steel plate:

carbon C content: ≤0.18, silicon Si content: ≤0.50,

manganese Mn content: 0.90-1.60, phosphorus P content: ≤0.025

Sulfur S content: ≤0.025, Copper Cu content: ≤0.35,

Chromium Cr content: ≤0.20, Nickel Ni content: ≤0.40,

CCSDH620 has good comprehensive mechanical properties, welding properties and process properties. It is suitable for the manufacture of ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities and other structural parts in ocean-going, coastal and inland navigation areas. It belongs to the special class of steel, and there are many large cargo ships and passenger ships that are very much in need of this kind of ship plate.
