Provisions on Application of Q235 Series Steel Plates

D.l The provisions on the application of Q235B and Q235C steel plates specified in the "Hot-rolled

Plates and Str中s of Carbon Structural Steels and High Strength Low Alloy Structural Steels" GB/T

3274-2007 are as follows :

a) The chemical composition (heat analysis) of steel shall meet the provisions of the "Carbon

Structural Steels" GB/T 700-2006, however, the phosphorus content and sulphur content noted in the

quality ce11ificate of steel plates shall meet the requirements ofP三0.035% and S三0 .035%.

b) The steel plates with thickness larger than or equal to 6mm shall be carried out with impact

test, and the test results shall comply with the provisions of GB/T 700. As for the Q235C steel plates

that are used at temperature less than 20.C~0.C and with thickness larger than or equal to 6mm, the

vessel fabrication organization shall conduct the additional O.C impact test on transverse specimens,

the average value of the impact power of three standard impact test specimens shall be: KV:立2刀， the

minimum impact power of one test specimen and the impact power value of subsize impact test

specimens shall comply with the corresponding provisions of GB/T 700;

c) The steel plates shall be carried out with cold bending test, and the acceptance criteria of

cold bending shall comply with the provisions of GB/T 700;

d) The design pressure ofvessel shall be less than 1.6MPa;

e) The application temperature of steel plates: shall be 20 .C~300 .C for Q235B steel plates and

shall be 0.C~300 .C for Q235C steel plates;

。 The thickness of such steel plate used for the vessel shell: shall not be larger than 16mm for

Q235B 创ld Q235C steel plates. The thickness of such steel plate used for other pressure components:

shall not be larger than 30mm for Q235B steel plates and shall not be larger than 40mm for Q235C

steel plates;

g) Shall not be used for the extremely 0 1' highly toxic medium.

D.2 The al\owable stress of steel plates shall be in accordance with those specified in D. l.

Note: The allowable stress listed for Q235B has been multiplied by the mass coefficient 0.85 . The allowable stress listed for Q235C has

been multiplied by the mass coefficient 0.90.

D.3 The negative thickness tolerance for steel plates shall comply with the corresponding provisions

of GB/T 3274.
