MECHANICAL PROPERTIES UNDER ROOM TEMP.
Heat treatment temperature and cooling: heat treatment
Tensile strength, Rm ≥ MPa: 930 ~ 1130
Yield strength, Rp0.2≥ MPa: 760
Elongation, A5 (%) ≥: 14.0
Hardness ≤ HBW: 288 ~ 331
PRODUCT DESCRIPTION
FV448 alloy is usually produced by AOD / EAF followed by electroslag refining (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.
Bars are usually supplied bright in the annealed condition.
Final heat treatment - quenched and tempered.
