The steel such as CCS FH32 naval vessels steel delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
Global CCS FH32 naval vessels steel crude steel production in March this year increased by 2.6 percent month on month and fell by six percent year on year to 147.1 million metric tons. accordina to the World Steel Association (worldsteel).In the first quarter of this year, global CCS FH32 naval vessels steel crude steel production decreased to 443.03 million mt, down 1.4 percent year on year.
We have 4 typical production lines CCS FH32 naval vessels steel, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.
In terms of ship steel, according to industry experts, steel is mainly used in the construction of ship hulls, cargo holds, piping systems (including pumps and valves) and part of ship decoration. In addition to being used to build conventional ships, steel also plays an important role in the construction of various special ships such as LNG (liquefied natural gas) ships, large oil tankers, large container ships, and chemical tankers.
