Re: FW: [MW:13105] Type of steel as per chemical proterties

Hi Naing
What I suggest here is get the chemical composition from your bolt specification and compare the PMI result (I did before with Metorex Arc Met-930) against the chemical composition from the specification. Now you can determine is it conform or not. I was always thought that we can not claim the material fall under YYY specification. Only manufacturer has the authority to make a judgment that the material fall under - let's say A105.

Dear,

Use latest equipment optical emission spectrograph, so u can all elements even lighter than sulpher. Match results with ASME II .

use optical emission spectrgraph for PMI and compare results with ASME sec II Part A or B.

Normal PMI equipment like XRF spectrometer cannot identify C.  From my
knowledge , it must be portable spectrometer or similar which will be more
expensive than normal PMI.  If PMI is required for stainless of which carbon
content is the issue such as  347H , it is possible that the client will
require PMI result with carbon content.

Dear How you identified carbon in PMI?..........

Dear friend,

This material is something like CK30. But this kind of material is heat
treatable and you have to sure about this. It is recommended to have a
metallographic test on it for undrestanding such a heat treatment.

Dear Experts,



We did PMI test on one unknown machine bolt from crane boom rest and result
is as follow:

Can someone tell me how can we trace the steel grade base on this result.

Is there any software available?



Thanks and Rgds,
