C.2 BS SP162 BS L37 Material C.2.1 Immediately before use or before refrigeration as described below, rivets to BS SP162 s

23、hall be heated uniformly at a temperature of495 5 C and quenched in water at a temperature not exceeding40 C. C.2.2 Rivets to BS SP162 commence to age harden immediately when kept at atmospheric temperature after quenching. Ageing may be delayed, however, by storing the rivets at low temperatures af

24、ter quenching, and they may be expected to remain in a condition suitable for closing for a period depending on the storage temperature as shown below: The rivets shall be closed within two hours of solution treatment if kept at atmospheric temperature or within two hours of removal from cold storag
