普碳鋼沸騰鋼板顧名思義是由普通碳素結構鋼的沸騰鋼熱軋制成的鋼板。沸騰鋼是一種脫氧不完全的鋼材，鋼液含氧量較高，當鋼水注入鋼錠模后，碳氧反應產生大量氣體，造成鋼液呈沸騰狀態而得名。

Plain carbon steel boiling plate as its name implies is made of ordinary carbon structural steel hot-rolled steel plate. Boiling steel is a kind of incomplete deoxidation of steel, high oxygen content in molten steel, when molten steel after the injection mould, carbon oxygen reaction to produce large amounts of gas, which is named after the boiling state of liquid steel.

沸騰鋼含碳量低，且由于不用硅鐵脫氧，故鋼中含硅量常＜0.07%。沸騰鋼的外層是在沸騰狀態下結晶的，所以表層純凈、致密，表面質量好，加工性能良好。

Boiling steel with low carbon content, and because there is no silicon deoxidation, so the steel containing silicon content is often less than 0.07%. The outer layer of the boiling steel is crystallized in the boiling state, so the surface is pure and compact, the surface quality is good, and the processing performance is good.

沸騰鋼沒有大的集中縮孔，用脫氧劑少，鋼材成本低。沸騰鋼心部雜質多，偏析較嚴重，力學性能不均勻，鋼中氣體含量較多，韌性低、冷脆和時效敏感性較大，焊接性能較差，故不適用于制造承受沖擊截荷，在低溫下工作的焊接結構件和其他重要結構件。

There is no large concentrated hole in the boiling steel, and the cost is low. The heart of steel boiling impurities, more serious segregation, non-uniform mechanical properties, more gas content in steel, low toughness, cold brittleness and aging sensitivity of large, poor welding performance, so it is not suitable for manufacturing under impact load, welding and other important components in low temperature.

沸騰鋼板大量用制造各種沖壓件、建筑及工程結構和一些不太重要的機器結構和零件。其材質的牌號、化學成分和力學性能符合GB700-79（88）（普通碳素結構鋼技術條件）中沸騰鋼的規定。熱軋中厚鋼板厚度為4.5-200mm。

Boiling plates are widely used in the manufacture of various stamping parts, construction and engineering structures, and some of the less important machine structures and parts. The grade, chemical composition and mechanical properties of the material are in accordance with the requirements of GB700-79 (88) (ordinary carbon structural steel). Hot rolled medium thick steel plate thickness of 4.5-200mm.
