[MW:690] Re: 688] Re: PMI TESTING OF SS 304L

DEAR Mr. RAGHURAM,

 

BUT SPARK EMISSION WHAT WE ARE ADOPTING HERE IS ARGON BASED AND MANY TIMES I FOUND PURITY OF ARGON IS NOT ENSURED. HENCE I AM RELUCANT TO GO FOR SPARK EMISSION FOR PMI OF LOW CARBON SS.

 

YOUR VIEWS PLEASE.

Why not? Infact only sprak emission method can detect C, as these are not portables instruments maneuvering at construction sites is very difficult

Both Arc met and PMI Master (see the other post by Mr Nadig, WAS is from oxford instruments, US) are gas based, where the principle of Spectro isort is quite different, it neither use Argon nor X-ray source.

 

However take care while using spark emission on lighter wall components

DEAR Mr. RAGHURAM,

 

THANKS FOR THE REPLY. JUST ADVISE ME IS IT RECOMMANDED TO USE SPARK EMISSION TECHNIQUE ON SS 304L MATERAIL FOR PMI.

 

AWAITING YOUR REPLY.

Probably spectro isort by Amtek can detect C, (thou I have not used it), you can try at www.spectro.com

 

Also Arcmet930 by Metorex can detect C

DEAR MEMBERS,

 

CAN ANYBODY TELL ME WHAT TECHNIQUE SHOULD BE USE TO PERFORM PMI OF SS304L. SINCE CARBON ANALYSIS IS VERY VERY IMPORTANT.
