AWS A5.17 suitable for mild steel and AWS A5.23 suitable for low alloy steel

The Definition of SAW Flux in AWS A5.17 Norm:

F ---- flux

7 ---- The minimum tensile strength is 70lb/mm

6 ---- The minimum tensile strength is 60lb/mm

A ---- The weldment should not be postweld heat treatment

P ---- The weldment should be postweld heat treatment (620℃ x 1h)

The letter and figures behind A or P means temperature required of impact V-notch (AKV 27joules)                 

For Example:

F7A2: A flux combines a wire to get a deposited metal. Minimum tensile strength of this deposited metal is 70lb/mm, the weldment should not be postweld heat treatment, and –29℃ should be required to get the minimum 27 joules of impact V-notch for the test piece.

 Type of Flux in above Recommended Table:

Sintered (Agglomerate):

CHF101, CHF101GX, CHF102, CHF103, CHF105, CHF113, CHF115, CHF301, CHF303 and CHF603.
