Some product sizes may not be available under ASME SA 333 Grade 6 Carbon Steel Seamless Pipes because heavier wall thicknesses have an adverse effect on low-temperature impact properties. ASME SA 333 Grade 6 Pipes are supplied with NACE MR 0103 AND NACE MR 0175 certifications with additions of HIC testing at low temperatures. ASTM A333 Pipe Specifications A333 Grade 6 A333 Grade

(a) Drop weight testing facility to study the impact behaviour and failure modes of CFRP/foam sandwich composite at low temperature  (b) Charpy impact testing facility to study the energy absorption of composite structures . Charpy impact test was a method utilised to study the energy absorption of GFRP laminates.
instead of lowering the test temperature. Impact testing is not required in the qualification of the welding procedures for weldments in Materials/components manufactured in accordance with M-CR-630 rev. 1 may be accepted. This C11 2 A 333 Grade 6 (1994) Seamless pipes C11 2 A 671 Grade CC60, CC70 (1994) Temp. reduction in sub size specimen for Charpy impact testWe have tested an A333 Gr.6 (4" pipe-6.3 mm thickness). Laboratory used a sub size specimen (55*5*10) and tested it at -48c. test temperature of A 333 Gr.6 is -45C (3 degree Celsius cooler temperature) Unfortunately absorbed energy was low and the test was failed. We see a clause in standard (SA-333/SA-333M) which described that:US standard Charpy V-notch impact specimen test Table 6 of ASTM A333 specifies a test temperature reduction of 4°C below the specified test temperature for Grade 6 because the material thickness is nominally 7mm. The impact test specimen width is only 5mm (71% of the material thickness) and Table 6 specifies a temperature reduction of 11°C.
