1. For SPHC, SPHD, SS330, SS400, SAPH370, SAPH400, SAPH440. the values in the table for tensile samples in rolling direction and bend samples in transverse direction; for TCX420L, TCX510L, the values in the table are suitable for samples in rolling direction.

2.For SPHC, SPHD, SS330, SS400, SAPH370, SAPH400, SAPH440, tensile samples with 50mm in gauge and 25mm in width would be used; for TCX420L, TCX510L, tensile samples with L 0 =5.65 would be used.

3.The width test of bend sample should not be less than 20mm, and equal to 20mm in arbitration
