Description
| The alloy is usually produced by BEF & AOD followed by electroslag remelting (ESR) / VAR if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements. 100% Ultrasonic test ASTM E2375 /SAE AMS 2154 /SEP 1923 /GB/T 4162 /EN 10228-3. Bars are usually supplied black/bright in the annealed condition. |
