Chinese mill of Grade AH40
shipbuilding steel plates: Grade AH40 steel plate is not as thick as possible in thickness. Thickness means stronger price, high purchase cost, and inconvenient transportation. Therefore, it is the steel material to follow. In addition, the thickness of the Grade AH40 steel plate is linked to Ping An, so the thickness of the steel plate is not arbitrary. The demand drawings require strict planning of the steel plate data. Thirdly, in addition to the thickness specifications of the steel plate, whether it can be used for another year or not, the steel plate is used, and some steel plates with long inventory time have been used. At the end, the thickness of the steel plate also needs to be checked. It is best to check the receipt. Some bad businesses will be short of two pounds. There are special testing things to deal with, and the differences are equally rejected.
Grade AH40 steel plate characteristicsJapan JISG 4051-79 (94) size steel number, primary carbon steel. This steel is Qijing steel manufactured by electric furnace, open hearth furnace or pure oxygen converter steelmaking method. It has high wear resistance and toughness. The steel has metallographic structure and processing function. S30C has higher strength and hardenability than No. 30 steel, medium weldability, medium cold deformation, plasticity, and good turning workability. It is used in the normal normalizing form, and is used to produce bolts, nuts, levers, and small items under high stress Components. (2) Supply form strength: 152 ~ 212HBS.
