30CrNi3MoV (675) high-strength steel is a new type of high-strength steel newly developed and put into use in China. It is a steel plate for armored vehicles. 30CrNi3MoV steel is developed by V microalloying on the basis of the original Cr-Ni-Mo series low-alloy ultra-high-strength steel, and appropriately adjusting the content of other alloying elements. The milling performance of 30CrNi3MoV steel is poor.
16MnDR steel plate is suitable for low temperature pressure vessels manufacturing. Grade 16Mn- indicates that the content of manganese (Mn) in the steel plate is relatively high, about 1% -1.6%, D- indicates low temperature, R- indicates pressure vessel. (Normally, when the content of a certain chemical element in steel is high, it needs to be marked in the material, for example, 1.6% manganese is written as 16Mn; certain elements such as Cr and Mo are higher, written as Cr1, Mo1, Such as 12Cr2Mo1R.) The normal delivery status is normalized delivery (Normalized).
ASTM A285 grade A standard specification for pressure vessel plates. A514 Gr Q QT steel plate, carbon steel, low- and intermediate-tensile strength. ASTM A285 grade A plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.Supplementary Technology: HIC Test I NACE MR0175 1 215 | Z25 | 235 | S57 | S57.1| S58 | S58.1 1S3 |S4 Thickness: 6MM to 300MM.Width: 1500mm to 4050mm.
