Becoming as 1 kind of steel, hot rolled steel plate is rolled under high temperature, its power is not very high but enough to meet the common requirement, its plasticity and solderability are the part we frequently make use of. Throughout or prior to the steel rolling process, the materials needs to be heated. The materials have to be heated until the temperature is above recrystallization temperature for rolling. The high temperature makes steel inner recrystallization and make it more optimum however the structural performance from the steel won't change.Hot rolled steel plate is of lower hardness, simple processing and much better ductility. While cold rolled steel plate is of high hardness and higher power, processing relatively difficult, but there is barely deformation. Hot rolled steel plate's power is lower, the surface high quality isn't that great because of oxidation brought on finish. Cold rolled steel plate has higher power, high hardness and high surface finish, usually utilized as sheet metal, and additionally, it can be utilized as stamping board. Mechanical efficiency of hot rolled steel plate is not as great as cold rolled steel plate or forged steel, however it has good toughness and ductility. Cold rolled steel plate having a particular degree of processing sclerosis, tenacity is low, but can achieve great yield ratio, utilized to create spare parts this kind of like cold bending spring.
Below would be the applications of hot rolled steel plate.
Steel plate for high pressure vessel use: outfitted with good processing performance and higher crushing power, utilized in the production of higher stress gasoline pressure vessel for containing LPG, acetylene and numerous kinds of gasoline.
Weathering steel: add special elements like P, Cu, C and so on, with a good corrosion resistance and atmospheric corrosion resistance, used for container, special vehicle creating, also utilized in architectural structures of developing.
Stainless steel plate: stainless hot rolled steel plate has good corrosion resistance, primarily utilized for that food business, surgical gear, aerospace, petroleum, chemical industry, etc.
Unique steel rolling: common mechanical structural steel plate are carbon steel, alloy steel, tool steel following the warmth therapy utilized in all kinds of mechanical components production.
Car structural steel: high power steel plate which has good drawing efficiency and welding properties, used in automobile frame, wheel as well as other creating.
Original steel for cold rolling: hot rolled steel plate can used as the raw materials for that production of all sorts of cold-rolled products, including CR, GI and so forth.
Prepainted Steel: production are common structural steel and welding structural steel, primarily used for the steel construction, bridges, ships, vehicle producing.
So far as we are able to see, our nation is in a large financial development period of history, with the rapid improvement of our economic climate and the growing of national power, infrastructure is creating vigorously, and also the demand for hot rolled steel plate is substantial and many, the increasing infrastructure in China will provide potential space for the application of hot rolled steel sheet.
