XRF Testing Machine

[Brad93]

Anyone in Essex or locality got an XRF tester.

I have a mystery stainless steel part to repair and it’s very magnetic but has been exposed to wear and subsequent work hardening no doubt.

If you get stuck, we have PMI (XRF) but not local. There was always a rough rule of thumb that 304 was slightly magnetic and 316 never was, but I'm forever finding non-magnetic 304 and slightly magnetic 316...

work hardening an austentic will only make it slightly magnetic.

As I think you probably saw in the video this part is highly magnetic.

I tacked it together autogenously to get it back into the right geometry and then made a support for the tip. Tacked that with a bit of 316 and no cracking yet so fingers crossed.

Im picking up 309L tig rod tomorrow. I’m going to have to Tack some 304 strong backs across the joint before I can v Prep the other side. I did it nice and slow making sure not to cause any heat spots etc.

440c is a good guess. Loved by certain food processing companies. I make heater blocks out of it for heat sealing bags in a food packaging company

Bump, again looking for someone to carry out PMI on a bronze part.

anyone know somewhere in the south east?

have a look at a local scrap yard
FJ Church from Rainham advertise they have xrf capabilities
they might do it for a nominal fee or a donation to the brew fund

Benfleet Scrap;m, who take our metal, are going to do it for me tomorrow FOC.
