SA203 Gr.F steel plate

SA203 Gr.F steel is the element of nickel is 3.25% to be used in manufacturing pressure vessel and boilers steel grade. SA203 Gr.F steel plate should be heated by heating into the austenitic range, quenching in water and tempering at not less than 1100 degree for not less than 30 minutes.

The max thickness is 100mm. if you need more thickness, Gangsteel also could supply for our customers. We also could do the third party inspection in CCS, BV, ABS, LR, KR, GL, DNV, CE, and others to promise the quality for our long cooperation.

Steel plate SA203 Gr.F, compare with SA203 Grade A, SA203 Grade B, SA203 Grade D, and SA203 Grade E, the yield and tensile strength are the highest to 380Mpa and 550Mpa. That is better in weld ability to boiler steel and vessel.

Gangsteel has much experience exporting boiler plate in SA203 Gr.F to factory mill many years. Besides that, Gangsteel has a specialized person who worked at production line of steel, to arrange our customer goods to produce as early as possible. Gangsteel welcomes our customer to visit in our mill.
