Note 1 Steel grades TH520,TS550,TH550,TH580 and TH620 are usually delivered double reduced, all other red double re reduced, all other grades are delivered single reduced. delivered single reduced. Note 2 Table represents the grades in common use. Other grades are available for specific end uses. Note 3 TS260 is a new grade introduced as an intended replacement for TS245,as it has a wider range of applications. Note 4 The deviations shown refer to measurements of individual samples. Note 5 The deviation of 50 shown in this table represents the normal range within the specified grades. For special requirements a tolerance of +/- 40 can be supplied. Note 6 The tensile testing of tin mill products is being reviewed. The above values are therefore intended as a guide based on the values currently available. Note 7 Batch annealed grades should be designated with the letter S. Continuous annealed grades should be designated with the letter H. Note 8 Informative annex I gives a list of former designations.
