A517GrP steel plate fixed rolling, A517GrS American standard high-strength plate, A517GrA correspond

A517GrP steel plate is suitable for welding boilers and other pressure vessels with quenching and tempering of high-strength alloy steel plates; The ASTM A517/A517M standard includes many grades of steel manufactured by different manufacturing plants, but all have the same mechanical properties and comprehensive properties.

A517GrP/A517GrS/A517GrA steel plate fixed rolling: Wugang Xiangyang

ASME SA517/SA517M standard includes the following materials: SA517GrA, SA517GrB, SA517GrH, SA517GrS, SA517GrP, SA517GrF, SA517GrE, SA517GrQ; The ASTM A517/A517M standard includes the following materials: A517GrA, A517GrB, A517GrH, A517GrS, A517GrP, A517GrF, A517GrE, A517GrQ. The two are completely equivalent to

Wugang Offshore Engineering Steel Variety Series

, which conforms to the A420~E690 (AQ43~EQ70) series of ABS, DWV, GL and CCS classification society specifications;

Supply size: 8~140×1500~3800×3000~12000mm

, in line with ASTM standard requirements A514GrQ, A517GrQ and Modified series;

Supply size: 8~215×1500~3500×3000~12000mmThis

type of steel has good hardenability by adding an appropriate amount of alloyed elements such as Ni, Gr, Mo and other alloyed elements.

The quality characteristics

of Wugang marine engineering steel are high purity and low impurity content, which can reach [P] ≤0.008%, [S] ≤0.002%, [N] ≤50ppm, [H] ≤2ppm, [O] ≤15ppm;

The composition fluctuation range between different heat of the same specification of the steel plate is small, the performance control of the steel plate is uniform, and the difference between the same plate is small;

The intrinsic quality of the steel plate can be according to China (JB4730; GB72790), the United States (A435, A578), Japan (JISG0801, JISG0901), Germany (SEL072), France (NFA04305) and forgings (GB/T6402) and other flaw detection standards to organize production and inspection and acceptance;

low-temperature impact toughness reserves;

Good resistance to lamellar tears;

The tolerance of the steel plate is strictly controlled, the plate shape is flat, and the surface smoothness and unevenness can be controlled below 5mm/m.
