Remarks:

1.For SB450 of over 25mm in thickness, the content of C may be designated to be within 0.30%, and that of Mn may be within 1.00%.

2.For tension test pieces, No.1A test piece shall be used for the steel plates of 50mm or under in thickness and No.10 test piece for that over 50mm.

However, for the steel plates over 40mm in thickness, No.10 test piece may be used.

3.The elongation of No.1A test piece cut off from the steel plate under 8mm in thickness shall be the values in the above Table reduced by 1% for

every decrease of 1mm of thickness or its fraction.

4.The elongation of No.10 test piece cut off from the steel plate over 90mm in thickness shall be the values in the above Table reduced by 0.5% for

every increase of 12.5mm of thickness or its fraction. However, the reduction shall be limited to 3%.

5.The bend test may be omitted unless otherwise specified by the purchaser.

6.When the elongation of No.1A test piece cut off from SB450M and SB480M steel plates of over 6 mm to and excluding 20 mm in thickness is more

than the value specified in the above Table subtracted by 3, the test piece shall be accepted despite the above specification. Provided that the value

of elongation in the guage length of 50 mm including the broken part is 25% or over.

7.Grade SB480M shall be normalized if exceeding 38mm in thickness.
