壓力容器板用于制造蒸汽鍋爐、壓力容器及其他承壓容器結構件用的鋼板。這種鋼板由于承受一定的氣壓和水壓，以及不同溫度的使用環(huán)境，如高、中、低溫等，因此對這種鋼板要求較為嚴格。除要求一定的強度、韌性外，還要求材質(zhì)均勻，嚴格限制有害缺陷。
A steel plate used in the manufacture of steam boilers, pressure vessels, and other structural parts of pressure vessels. The steel plate is subjected to a certain air pressure and water pressure, as well as the use of different temperatures, such as high, medium, low temperature, and so on, so the steel plate is more stringent. In addition to requiring a certain strength and toughness, but also requires uniform material, strict restriction of harmful defects.

壓力容器板種類：按成分分類可分為碳素鋼板、合金鋼板兩大類；按強度分類可分為高、中、低壓鋼板；按使用環(huán)境分類可分為高、中、低溫用鋼板及耐腐蝕鋼板。
Pressure vessel plate type: according to the composition classification can be divided into carbon steel and alloy steel two categories; according to the intensity of classification can be divided into high, medium and low pressure plate; according to the use of environmental classification can be divided into high, medium and low temperature steel and corrosion resistant steel plate.
壓力容器板的厚度范圍一般為5～200mm，期間分為 若干厚度規(guī)格。各國標準都列有推薦的板材尺寸及允許偏差。鋼板的形狀：如鐮刀彎、平面度、直角度等。表面缺陷：鋼板表面缺陷主要有裂紋、結疤、碾平的氣泡、雜質(zhì)、凸泡、氣孔、壓入氧化鐵皮等。出于安全的需要，壓力容器鋼板對表面及內(nèi)部缺陷要求較為嚴格。一般不允許上述缺陷存在。
The pressure vessel plate thickness range is generally 5 ~ 200mm, during which is divided into a number of thickness specifications. National standards are listed for recommended sheet sizes and tolerances. The shape of a steel plate, such as a sickle, a plane, a right angle, etc.. Surface defects: the surface defects of steel plate mainly include cracks, scars, flat bubbles, impurities, protruding bubbles, pores, and so on. For safety needs, the pressure vessel steel plate requires strict surface and internal defects. Such defects are generally not allowed to exist.
