What lead you to believe your current guide was stainless? It could be, ferritic and martensitic grades are magnetic if I'm not mistaken.
If there's a met lab nearby, having a hardness check and OES analysis for alloy composition could be done within a matter of a day or two at most if you're...
Depends on what the weld is designed to endure...
That said, if it's a structural weld, odds are you'll want to avoid formation of untempered martensite in the HAZ. Not sure of the exact hardness range, but I'd guess if you apply pre- or post-weld heat treat and see hardness readings at or...
Thank you both for the responses.
Swall - do you mind sharing with me what coolant you've had success with? We're currently using a coolant that we're not tremendously satisfied with (giving us poor tool life, expensive, etc.) and I wouldn't mind running trials with new coolants.

Hello all! I'm currently experiencing issues with soft spots on carburized producted due to surface masking (confirmed by metallographic examination, hardness testing, carbon analysis, etc.) - similar to that described in the referenced thread above.
Some background - the...
