pre-WPS of GTAW for Mat'l stainless 310 grade

[QualityAsia]

I am preparing pre-WPS of GTAW for Mat'l stainless 310 grade(Base Metal). But Mat'l stainless 310 grade is hardly to find in my country, so I will use Mat'l stainless 304 grade instead of 310 grade. Filler metal is ER310 and impact test is not required,

Pls. kindly share exsperience and knowlendge,

Thanks & regards,

QualityAsia.

Your approach is acceptable. All you need is to qualify on P-No 8 base material under Section IX.

if the client requires chemical analysis, you will have to get some 310 plate/pipe and 310 tig rod
