31、ts are applied to the rolling ingot and/or 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 develo
32、pment of coarse grain. cDue to possible problems 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. Howev
33、er, although T761 and T762 properties should 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 3332:2005 (E) 6 100 Product qualification See EN 4
