Adopt standard: ASME SA302
Sell steel grade: SA302 Grade A ,SA302 Gr.B,SA302 Grade C, SA302 Grade D steel grade
SA302 Gr.B steel plates standard specification for pressure vessel plates in alloy steel, manganese molybdenum and manganese-molybdenum-nickel.
SA302 Gr.B steel grade is min yield strength in 310Mpa. Gangsteel also supply the Ultrasonic test in thickness in A435/A435M, A577/577M and A578/A578M to promise the perfect quality in long cooperation.
SA302 Gr.B steel plate shall be normally supplied in the as-rolled condition. Plates may be ordered normalized or stress relieved, or both. If SA302 Gr.B steel plate is above 50mm in thickness shall be normalized.
