GB/T 33963-2017Steel plates and sheets for truck carriage (English PDF)

Foreword

This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.

1 Application Scope

This Standard specifies the designation, ordering content, dimensions, shape, weight, technical requirements, test methods, inspection rules and packaging, marking and quality certification of steel plates and sheets for truck carriage.

This Standard applies to hot-rolled steel plates (including hot continuous rolling shear steel plates) and sheets (including longitudinal cutting steel sheets) of thickness 1.2 mm ~ 12.0 mm for the cold forming and wear-resistant parts of truck carriage.

6 Technical Requirements

6.4.2 The Charpy (V-notch) impact absorbed energy is calculated as the arithmetic mean value of three samples; it is allowed that a single value of one of the three samples is lower than that specified in Table 5, but not lower than 70% of the value specified.

6.4.3 For Charpy (V-notch) impact test of steel plates and sheets of thickness less than 12 mm, samples of small dimensions shall be used. The dimensions of the samples of steel plates and sheets of 8 mm < thickness < 12 mm are 10 mm × 7.5 mm × 55 mm, and the test result shall not be less than 75% of the value specified in Table 5; the dimensions of the samples of steel plates and sheets of thickness 6 mm ~ 8 mm are 10 mm × 5 mm × 55 mm, and the test result shall not be less than 50% of the value specified in Table 5; impact test is omitted for steel plates and sheets of thickness less than 6 mm.
