ASTM A182 F51 forging Ratio and Which ASTM examination method to reveal material flow line

ASTM A182 F51 forging Ratio and Which ASTM examination method to reveal material flow line

ASTM A182 F51 forging Ratio and Which ASTM examination method to reveal material flow line

(OP)
In general, standard minimum forging ratio is 3:1 for open-die forging method.
Forger actual performed base on ratio 5.5:1 on F51 forging of valve component(closure).
How does this forging ratio leads to the better material flow lines ?

How & what checks are performed to see whether the material flow lines conform approximately to the final shape of forging (eg.valve component-closure)?

Which ASTM standard to be used to examine material flow line of A182 F51 ?
ASTM E381 or E340 is the right standard ?)

Appreciate expert's advice.
Thank you.

RE: ASTM A182 F51 forging Ratio and Which ASTM examination method to reveal material flow line

ASTM E340 is the correct standard for a forging. ASTM E381 is for billets and other products with a cast structure.

A higher forging ratio breaks up the original cast/dendritic structure and any inclusions resulting in more benefical flow lines.
