The mechanical properties of hot rolled steel plate are far less than that of cold working and forging, but the hull structural GL-F36 shipbuilding plate, hot rolled steel plates have better toughness and ductility. Cold rolled steel plate has a certain degree of work hardening and toughness is low, but it can achieve a better yield ratio, and can be used for cold bending spring leaf and other parts. At the same time, because the yield point of cold rolled steel plate is close to the tensile strength, the danger is not foreseen in the use process, and accidents are prone to occur when the load exceeds the allowable load.
The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, hull structural GL-F36 shipbuilding plate. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.
Global hull structural GL-F36 shipbuilding plate 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 hull structural GL-F36 shipbuilding plate crude steel production decreased to 443.03 million mt, down 1.4 percent year on year.
