SA516 Gr65 sheet is a carbon steel plate for medium and low temperature pressure vessels. It implements the ASME standard of the American Standard. It can provide a minimum thickness of 8mm and a width of 1500~4000mm. The CCS grade D hull shipbuilding plate product thickness direction (Z-direction) resistance to tearing and wet hydrogen sulfide corrosion can be added Performance (HIC+SSCC) steel. Steel used to manufacture pressure vessels for petrochemical, gas separation and gas storage and transportation equipment.

CCS grade D hull shipbuilding plate, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.

In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our CCS grade D hull shipbuilding plate quality. Till now, we keep exporting around 100 tons per month as regularly.
