CCSEH420 steel plate steelmaking process: the steel plate is smelted by an electric furnace or converter, and if necessary, it should be refined outside the furnace.

CCSEH420 steel plate binding size: thickness: 8-150mm, width: 1600-4000mm, length: 6000-17500mm.

CCSEH420 steel plate can be produced according to the needs of users in different countries of marine steel, such as the United States, Norway, Japan, Germany, France, etc., its classification society certification is as follows:

China CCS United States ABS Germany GL France BV Norway DNV Japan NK UK LR Italy RINA South Korea KR (Norway DNV and Germany merged into: VL, nine classification societies certification.

CCSEH420 surface quality:

CCSEH420 this standard stipulates: "There shall be no harmful defects such as bubbles, scarring, cracks, folding, inclusions and pressing into the iron oxide scale on the surface of marine steel." There should be no delamination on the marine steel end face". "The surface of marine steel is allowed to have a thin layer of iron oxide scale, rust and inconspicuous roughness, reticulation, scratches and other local defects caused by pressing into the iron oxide scale and rolling, but its depth shall not be greater than the negative deviation of the thickness of the steel, and the small thickness allowed by the steel shall be ensured. "

Cutting process: CCSEH420 steel plate factory inspection of the performance indicators meet the requirements in accordance with the cutting process, can be cut processing and drawing blanking, the general thickness of the steel plate is not more than 20mm, the preferred choice of CNC plasma cutting or CNC laser cutting, if the thickness of the steel plate is greater than 30mm, usually CNC flame cutting will be selected, you can control the cutting accuracy and time.
