GB/T 11251 30CrMnSiA hot rolled structure steel plates mechanical properties:
1) The mechanical properties of steel plates delivered in annealed state shall be in accordance with the provisions of the table below. The Brinell hardness of 30CrMnSiA is measured only when the demand is required.
2) The steel plates delivered in normalizing state, under the condition of elongation comply with the table, the upper limit of tensile strength is allowed to be increased by 50Mpa.
3) The steel plates with thickness above 20mm, when the thickness is increased by 1mm, the elongation is allowed to lower by 0.25% (absolute value) than that of the table, but it should not exceed 2% (absolute value).
