30、 sheet/strip to avoid incipient melting (overheating). bIt is recommended that material in the O delivery condition shall not be formed, stretched and/or straightened in excess of approximately 3 % before solution heat treatment, in order to avoid the development of coarse grain. cDue to possible pr

31、oblems of test piece distortion after solution heat treatment and quenching by the purchaser, fracture toughness tests may be carried out on material in the T761 condition, in which case tensile tests shall be carried out in both T761 and T762 tempers. However, although T761 and T762 properties shou

32、ld be similar, it should be recognised that the latter may be affected by the purchasers processing and practices and, accordingly, T762 properties cannot be guaranteed by the manufacturer. 99 Typical use EN 3333:20056 100 Product qualification See EN 4400-2.
