                                   Weight = kg /m

NOTE : The values shown in this table are based on weights for carbon steel. (Density7.85 g/) So, the different grades of stainless steel permit considerable variations in weight(The ferritic stainless steel may be about 5% less, and the austenitic stainless steels about 2% greater.)
